Re: [Asterisk-Users] Nested MySQL Commands

2006-01-11 Thread Chris Albertson



 Send a 
 query over to the MySql server with only the required 
 parameters and have it do all the processing for you and 
 only returns the results.

THe above describes the whole point of a SQL DBMS Server.
WHat else could you ask one to do for you?

Back to the original question:  Can you use the result of
one query to feed another without going to the DBMS twice?
Yes, Of course SQL allows this.

In fact Data base experts
would be horrified to see any code that querries a value,
holds that value and then querries based on that value.
Doing this without holding a lock on the relevent tables is
just plain wrong and will result in bugs.  You should
_always_ write the SQL querry such that only one querry
gives you the results you need.  Manual Locks are not good, they
can be the source of very serious performance problems.

For more specific advice you would need to post the details
of what you are tring to do and a bit of the SQL you are
using.

 
 I know that is a nice feature od Microsoft Sql. But have 
 not had a chance to read up on the performance of the new 
 version of MySql...

Basically MySQL is very fast when the load is light but scales
very poorly with either higher loads or higher conplexity
querries.  It is good for flat file like problems.  The
larger DBMSes are slower initially but scale better.

Re: [Asterisk-Users] Nested MySQL Commands

2006-01-11 Thread Chris Albertson

Under Linux (and other OSes) It's not as bad as that.  Even with
128 Perl processes running there is only one copy of the Perl
interpeter in memory.  Each of the 128 running processes would
have it's own copy of only it's data segments.  With Perl
already in memory the biggest system overhead would be
process creation.

The best design is the one that minimizes the number of
process that the kernel has to create.  Notice that this is
why the Apache Perl modual is so much faster than using
Perl from a CGI script

Perl connecting to a central DBMS server is already the model
you describe: 128 light weight procees connected to one
big process which is the DBMS server.

Performance gains will come from writting the SQL so that there
is only one transaction and using indexes on the right
columns in the database.

If you really do have 128 process runing and each one needs
to access a DBMS server, I'd say you are going to need a
very powerful DBMS system but likly the call volume is not
neraly like that

   the perl script. This has many advantages. One disadvantage
 however
   is that potentially, there could be 120 simultaneous instances of
   this script running (one per call).
 
 Yes, but if you need it to scale efficiently, each of these could
 be a very lightweight process. If you used each of these to
 communicate
 via RPC or shared memory to a process with a small and configurable
 pool
 of database connections (which isn't that difficult), you can build a
 simple and scalable solution.

Re: [Asterisk-Users] mpg123 removal

2006-01-09 Thread Chris Albertson

Almost certainly a memory leak in mpg123 is not the cause of a system
crash.  First off, there is no such leak.  Second even if there were
one
the mpg123 process is not long lived.  A new one is started for each
MOH session.

If mpg123 is causing the crash then it may be due simply because of
all the extra CPU time required to transcode the music.  If there are
10 lines on hold then there woud be 10 copies of mpg123 running
on the server.  

As per the suggestion below it is smarter to transcode the music
file ONCE and save it.   sox is a pretty good transcoder.

Also, be carful what music files you use for MOH.  Rebroadcasting
copywrited music is not lega;.  If the wrong person happens to
call, be put on hold and hears your unlicensed MOH you could
get in trouble.  People who work in the entertainment industry
tend to be sensitive to this issue.  Use some crative commons
works and you will be OK.

 rm /usr/bin/mpg123 or something like that
 
 There are a few solutions to MOH:

 http://www.voip-info.org/wiki-Asterisk+mpg123+faking+it
 
 If you are using 1.2, I would use native (codec, not MP3).  There
 should 
 be an example in the sample config file in 
 /usr/src/asterisk/configs/musiconhold.conf.sample - I don't see it on
 
 the Wiki.  It should be there, somewhere.  Must be buried.  For this 
 option, you will need to have the sound files in .ul, .gsm, or
 whatever 
 codec you use mostly.  I only allow ulaw, so all of my MOH files are 
 .ul.  This way it doesn't have to transcode at all.

Re: [Asterisk-Users] Stay away from Grandstream!

Maybe a better way to say it is Know the limitations of the GS phones
and don't try and use them outside of those limits.  Don't buy ANY
phone you've not tested and used yourself for use by a client.
My GS phone has worked fine for years.  Even if it were to fail
and had to be replaced buying two is still cheaper then one of
some of the others.  The trick is to use them (or anyhting else)
only when you know it will work.  That said, the GS 100 is not the

Re: [Asterisk-Users] Festival questions

2005-07-14 Thread Chris Albertson

I was working on something like this.  There are a few
isues:

(1) First off yes you have to have access to the tesxt of the
e-mail.  Notice the word test we don't want html or
MS word atachments.

(2) Next look below nice al the silly junk like quotes are
indicated by  marks.  This has to be converted.
The the ascii art in the sig line.   OK this is not hard
just a whole bunch of Perl scripting or if you are really nuts
like me try lex/yaac to define an e-mail grammer
There is much to be done here basically we are building a
script that any reader (human or machine) would be able
to read into a telephone.  The BEST format to use a voice
markup language not plain text.  Festival can read the
markup language

(3) Finally you spimply scrip it and run it on as command
line application on _many_ test emails and listen.

(4) assuming #3 above is done integrating it into * is very
easy.  One interrresting idea would be to automaticaly
drop email into voice boxes oruswer could us a menu tree


If anyone seriouly wants to work on the above isues please CC
me directly about it.  Im my opinion most of the work is
in #2 which would be implemented outside of the * code base
as a stand alone application.

Re: [Asterisk-Users] Backup for linux/asterisk

2005-03-24 Thread Chris Albertson

The standard UNIX backup program is called dump.  Try reading the
dump manpage by typing man dump at the shell's prompt.  This program
has been in common use since maybe the late 80's

Quoted from the man page:

  Dump examines files on an ext2/3 filesystem and determines
  which files need to be backed up. These files are copied to
  the given  disk,  tape or  other storage medium for safe
  keeping

Many sysadmins will run dump nightly from a crontab entry

2005-02-24 Thread Chris Albertson


Mark,

You are getting close to doing what I was thinking of.

Let's say your repeater system works with sub-watt power
transmitter and a little 1/4 wave antenna.  You could
get about a mile of range with a shirt pocket sized HT.
OK so for that's easy.

Next you get 50 of your freinds to build systems like that.
then you connect all the asterisk boxes with AIX.

What you've have then is a cell phone system running on VHF.
If you had an LDAP server that culd be kept up to date with
what call sign is in the range of which cell you could make
worldwide call sign to call sign calls.

Also, with low power xmiter lots of people could afford ot
git into it.  

THere are more things one could do with Asterisk and radio then
one person could ever cover.  I've been wanting to start
up some kind of interest group

 On my repeater system, I use the RC210 repeater controller with the

 Users can initiate phone calls and callers can either command the

 There are many Phone patch type devices that could be paired with a

2005-02-24 Thread Chris Albertson

THat is a valid conern if there is a path from the PSTN to a
ham licenced transmitter then any unlicenced person could
get on the air.  Isues like that could be worked.  Software
even enforce any rule such as requiring operators present at
control points or PSTN disconnect before IRLP connect

You could build a system that talks to multiple services but
never allows them to be connected in real time

Re: [Asterisk-Users] Sphinx

2005-02-16 Thread Chris Albertson

In a production environment, I would not attempt to run Sphinx on
the same computer as Asterisk   A few users interacting with
Sphinx could consume all of the server's resources and then some.

Same goes for DMBS servers, One big N-way join could tie up a
CPU for tens of seconds.

RE: [Asterisk-Users] speech recognition V 2.0

2005-02-16 Thread Chris Albertson

 Sphinx and Festival are good projects. The last I worked with sphinx
 I
 was told that it would need modifications to make it more grammar
 aware,
 but that was 2 years ago and things may have improved. If not then
 Sphinx people please let me know when you will add grammars natively
 or
 refer me a grammar based engine.

Sphinx and Festival are in fact the current state of the art.
you are not likely to find anything better.

Sphinx can return a probibility network.  You can then attempt
to parse paths through the network and use the first path
(searching in probibillity order) that parses correctly.

You can use a LEX/YACC parser and do well enough.  (Get the
O'Reilly LEX/YACC book.  It's easy to use.)  I'm impressed with
YACC's performance.  I have an application with hundres of
grammar rules that runs as fast as UNIX's wc utility.

Users _can_ learn the subset of grammer.  Remember the game
zork or the other text based adventure games?  People caught
on to the limited subset of English.

Re: [Asterisk-Users] Re: load balancing 20 asterisk servers

2005-02-02 Thread Chris Albertson


DNS based load ballancing has it's place, as dose using an
application level switch.  

Say an earthquake takes out your California data center.
Shortly the DNS servers will notice and pull that center's
record.  However do to caches and all this is not fast
and users will notice.

What the switch does is route at the protocol level between
local machines.  You can take a machine off line and no one
will notice.  Works great until the big quake a backhoe
takes out a fiber cable ro there is a fire flood or who
knows what.

protocol level switches have to know about the protocol.
You can buy them that work with HTTP, HTTPS and the common ones
but I wonder aboit SIP?  Getting the RPT to the right * server
would be hard beetrer to have a proxy tell the user which *
server to go to and nothave to route RTP.

 Are you shure of that? I'm aware that the load criteria is trickier,

 If you use DDNS (dynamic DNS) using Bind 9. You have to run a health
 monitor (like a tcp
 or ping monitor) in one server (like the dns one) if one server dies,
 a script removes
 it's A record automagically from the pool, and even with a script
 that monitors the load
 you can dynamically add and remove the entry of each individual
 server in the DNS server.
 And you would not need to care if the load balancer sends the SIP
 stream to one server
 and the RTP stream to an other or in the case of outgoing connections
 or whatever
 extrange situation.
 
 Use nsupdate utility for doing DDNS, it's really simple and
 incredibly powerfull. Also
 because all the requests are digitally signed, you will likely don't
 have security
 problems.
 
 
 
  You may want to consider a simpler aproach, why don't you balance
 the load via DNS?
  If you put in a zone file various A records for the same machine,
 but with different
  IP's, BIND will catch the trick and send a different IP (from the
 pool yo defined) each
  time a DNS request arrives. That's a simple way of doing that, it
 will definively work
  for termination, but you may have to think more who to cope with
 origiation (outgoing

 Indeed, I'm thinking of using 2 CompactFlash ATA disks. One fully

 need 
 to change/save the config). No worries about unclean shutdown.
 
 The second disk I will use for voicemail, and I can swap it every
 year 
 before it wears down.

Better than that, mirror the disk.  Then when one drive fails
Linux will automatically use the other disk.  You can go one step
more and define a third disk as a hot spare then after Linux
detects the drive failure and switches to the surviving twin
it will also bring up the hot spare and begin building a replacement
for the dead twin.  You can then swap out the dead drive with no
need to power down the server and declare the new drive as the
new hot spare  I would mirror the read-only patition also

It you truely want 5 nines you have to set things up so that you
can do normal maintanance (swapping out drives, power supplies and

 It's probably possible to do it with another distro too but astlinux
 is 
 already pretty much finished :) And the cost of 512 Mb or 1 GB ATA
 flash 
 is not much more than a McDonalds meal anyways (1GB is about USD 100
 now)
 
 For voicemail I could also use a microdrive but I'm not sure what
 will 
 happen if it breaks and * tries to read/write from it. If that would
 bring 
 the box down it's no solution.

RE: [Asterisk-Users] UPS for Asterisk

2005-01-24 Thread Chris Albertson


The usual setup for a computer is hosting a critical functions is
to use a server that has two (or more) power supplies with an
A/C power cord comming from each.  You then connect each cord
to it's own UPS.  I typical small PC server would have two
internal power suppies and two UPSes.

With this kind of setup even the cruddy UPS describbed below would
be just an annoyance and the system would not go down.

 The second one lasted two or three years, then suddenly started

Re: [Asterisk-Users] Asterisk Interface to propriotary system and GPL

2004-12-22 Thread Chris Albertson


If everything on the Aterisk side of the socket is GPL'd
I think you are OK.

Look at the example of a Linux system running Netscape
browing the web when there is a Microsoft HTTP server.
Then we have a GPL's system conected to a closed
comercial system over a socket (port 80).

The grey area is when you link GPL's code to non GPL
I think the case of a socket interface is pretty clear.




--- Shahed [EMAIL PROTECTED] wrote:

 Hi All,
 
 I am wondering if I will be breaking the GPL,
 if I write for example, a channel driver or
 make some modifications to the astrisk source code,
 to interface at RUN TIME, through sockets, with
 a proprietary system.
 
 Eg.
 
 1. I write chan_xxx + modify asterisk source
 (make changes + new code publicly  available)
 
 2. chan_xxx supports hardware by XXX Corp.
 
 3, XXX Corps interface  is proprietary.
 
 4. I write a layer over XXX Corps API, that uses sockets,
 with the ONLY intent to BYPASS the GPL restrictions
 (If what I think about them are correct)
 
 5. Asterisk now interfaces at runtime with XXX,
 but no library linking.
 
 6. I sell the system, make all modifications available
  under GPL, but don't purchase any sort of license
  from Digium.
 
 I looked at http://www.netrino.com/Articles/LinuxLaw/
 and some ML posts, and it seems that perhaps I may be
 somewhat correct ?
 
 
 Please don't ask we why I would want to do this,
 because this is a hypothetical situation.
 I just want to clarify this, for maybe, future use.
 
 Thanks

Hey guys, Look at this example www.scubaboard.com It has nothing
to do with Asterisk but is an example of a _very_ high volume
meaasge board that _works_.  It runs on free software, has low
admin overhead.  It allows moderators on a per subject level and
optional authentication.  I have used this system both as a user and I
have installed and tested the software on my system.  It is easy
from both points of view.  Built in search, and even
e-mail subscriptions to threads.  Not much more to ask for.

This list is actually becomming usless do to it's success.  I
doubt I would notice a reply to this posting unless you CC me
off line and remove the  [Asterisk-Users] lable so it doe not
get piled in with 400 other messages.  

I suggest that people here actually try out scubaboard even if
you have no interrest in diving.  Check out the photos, for sale
ads, technical topics, regional/geographic forums and how it all
is kept straight and the search feature actually works to find
old threads.  And did I mentione-mail subscriptions to threads

 So
 unless you are running NNTP on a port like 80 or 443, it probably
 will
 be blocked. Even then a good admin would have a proxy in place to

   Better question is why do you feel there needs to be a change?
  
  You've missed some best of breed options.
  
  A newsgroup by itself may or may not be useful.  However, either
 way, 
  USENET (which isn't entirely limited to NNTP, incidentally) has a
 bunch of
  powerful clients that are designed from the ground up for
 participating in
  large threaded discussions.  This is a major failing of many mail
 clients.
  I find it easier to follow large discussions with the text-based
 trn 
  newsreader than with any graphical mail client I've seen to date -
 bar 
  none - and trn is old technology.  Just the thread tree view itself
 is so
  useful, not to mention one-key cruising through the tree nodes.
 
 Who said mail needs to be graphical? I know a great many people still
 using mutt for their mail and it probably will resemble trn close
 enough
 for your taste. Of course there are plenty of graphical email readers
 that support threaded views. I happen to use evolution with threads
 turned on and enjoy it.
 
 Your right, threaded trees are great. I love it when there is enough
 people using correct enough software to help keep the information
 correct. Of course we get to the same problem here that not all
 software
 mail or nntp actually puts the in-reply-to or references headers in
 to
 make the tree view work.
 
  Many sites gateway various mailing lists into local hierarchies,
 for the
  explicit purpose of solving some of the problems that NNTP doesn't
 solve,
  because the medium was designed to deal with the functional
 equivalent of
  mailing list traffic from day one.
 
 Gateway mailing lists to local hierarchies to solve problems that
 hierarchies doesn't solve? Sounds like broken hacks to me. Maybe in
 your
 rush through that sentence your meaning didn't get fully expressed.
 
 As for the design, like many older technologies, NNTP was designed
 before the unrulely behavior of spammers. While I know there are some
 private nntp servers that enable authentication to protect
 themselves,
 it isn't the norm.  
 
  You can avoid some of the problems of public newsgroups by making
 it a one-
  way gateway, with moderator pointing back at the original list,
 therefore
  subject to all the normal list posting controls.
 
 And a limit on what a moderator will be able to handle unless it is a
 program, and then it wouldn't take a moment to get past it. Not that
 email is any more secure.
 
  Setting up a one-way gateway isn't too difficult.  Is there
 interest?  I
  can certainly start one.  We already do all the FreeBSD lists and a
 bunch
  of other stuff here.
 
 I belive there has already been one with URL posted in this thread.

 Im 
 concerned.
 I simply can not use a system that sounds like people talking are in
 a 
 tunnel. At this point, this is the only point of failure that kills
 the 
 whole idea of using this as a real switch.
 
 Now, as far as echo cancellation, Ive looked as some of the docs,
 like the 
 motorola paper,
 http://e-www.motorola.com/files/dsp/doc/white_paper/PTECANWP.pdf and
 some 
 purely theoretical stuff, but their math is beyond me.
   Unless someone has developed a whizz-bang improvement over the
 stuff I 
 read, the point of transiting from a two wire to a 4 wire model will
 always 
 cause echo, period, done, abandon the idea, lets go do something
 else. The 
 limiting factor I see, is our software echo handling doesn't have the
 
 computational horsepower attached (no cpu, or stealing cpu cycles
 from main 
 cpu) to be effective. Does this mean another piece of expensive
 hardware? 
 Dedicated proprietary chips like the Moto? I'm thinking so.
 
 SO, This is it, critical point of failure...cant go on, at least I
 cant use 
 it. Yes, * does a lot of other stuff just fine, but this is the
 immovable 
 object, at least for me.. This is something it must do and do well or
 its 
 over.
 Ive been holding my breath, hoping something pops up, but it hasn't.

   or DTMF tones stopped working.

   I only get echo when dialing over the PSTN. Using Nufone to dial
 a PSTN

   Most of the telco's have technicians with the equipment

RE: [Asterisk-Users] Network Sniffing Calls for recording

2004-06-07 Thread Chris Albertson

Many people use ethereal to capture network packets.  I've used
it to debug SIP sessions.  

www.ethereal.com/ 

In theory one could re-contruct a phone converstion from logged
packets but it might take some effort and you'd need to be
pretty smart to find the packets from a call from Joe early
last week in the morning some time.

RE: [Asterisk-Users] Asterisk on Compact PCI platform

It can from an NFS mounted image just fine.  You don't

One other on-line resource:  http://zapatatelephony.org/

The _original_ driver was for BSD.  The folks at Digium
appearently ported it to Linux and likely improved it over
time.  But the old BSD driver is still there.

The zapata cards were a kind of open source hardware

Getting the old BSD driver to build would be a good first
step.

Re: [Asterisk-Users] RE: Shorewall and asterisk on Mandrake

2004-03-08 Thread Chris Albertson

I have your same setup: Asterisk running on a box that
also runs SAhorwall.  I can register to both WD and ICH.

One thing I suggest is first getting Asterisk to work
without shorewall.

Next install the firewall but leave it wide open, close it
down incrementally.  Also turn on logging of every dropped/rejected
packet and check the log file.  If shorewall is getting in the way
you will see the rejects to/from FWD or ICH in the log.

Ask me off-line and I can send some config files but be warned
they are more open then need be.  

--- Patrick Lidstone (Personal E-mail) [EMAIL PROTECTED] wrote:
 
  I am struggling getting asterisk to work on my firewall box.
  
  The Linux box is a firewall running Mandrake 9.2 and 
  shorewall for security and NAT. Asterisk is compiled and 
  running on the firewall box with a modified sample 
  configuration. I am connecting to it using a Sipura on the 
  local LAN. This works fine and I can phone between extensions 
  (2201 and 2202) and access the voicemail menu via extension '8'.
  
  Now, I cannot get asterisk to register the two SIP providers I want
 to
  use: FWD and ICH. The log reports that it did not register - 
  consequently I cant dial '6-612' to get the FWD date-speech. 
  
  I've configured everything according to the manual and 
  several example config files as referenced on voxilla. The 
  error message I get is a timeout on sip-registration and some 
  rtp timeouts. I assume its a shorewall issue.
  
  
  How do I need to configure Shorewall? (I have the following
 shorewall
  domains: net, masq, fw, loc used in the rules.conf) Does 
  someone have a sample shorewall config?
  
  How can I easily tell that asterisk registered properly with 
  the SIP provider?
  
  Could someone post some a current working sample configs for 
  FWD and ICH which indicate the use of the various fields 
  better than the existing
  samples:
  * For FWD I have 123456 (the number), AUTO_123456 (the user 
  ID), password.
  * For ICH I have 1234567890 (the number without 1) 
  11234567890 (the number with 1), 98765432 (the user id), password.
 
 Voxilla doesn't mean anything to me, but I went through a similar
 learning curve a while back. The key to successful registrations
 behind
 nat (for me) are the following entries in sip.conf. My asterisk box
 sits
 on a natted network 192.168.0.x with address 192.168.0.5
 
 ;
 ; SIP Configuration for Asterisk
 ;
 [general]
 port=5060 ; rtp port to bind to
 localnet=192.168.0.0  ; address space for local (natted)
 network
 localmask=255.255.255.0   ; netmask for local (natted) network
 externip=a.b.c.d  ; a.b.c.d is public ip address
 of your router
 outside_addr=a.b.c.d  ; as above
 bindaddr=192.168.0.5  ; where 192.168.0.5 is the IP address of
 your * box behind NAT
 nat=yes
 
 With these config changes, and asterisk restarted, you should be able
 to
 register ok (as reflected by sip show registry from command line.
 This
 is the crucial first step.
 
 In addition, for a bi-directional voice path you will typically
 require
 port forwarding of UDP traffic in the media port range specified in
 rtp.conf to the natted ip address of your asterisk box (192.168.0.5
 in
 this example). A typical rtp.conf file might look like this:
 
 [general]
 rtpstart=50600
 rtpend=50609
 
 You should also configure your firewall to pass UDP traffic
 bi-directionally on port 5060.
 
 It is worth persevering - asterisk does work behind a natted firewall
 with the likes of FWD just fine.

No,  It's not a 60Hz hum.  Yes, 60Hz is getting into the line
but the existing filters are removing the 60hz.  What he hears

a combination of various multiples for 60hz.  

I'd bet that the tiny speaker inside a telephone handset can not
even reproduce a 60Hz tome.  Yes you can hear a hum but it's
the overtomes of 60 that you hear.  Many people can not even hear
down to 60Hz, some can but not everyone.  

If you were to design a filter wouldn't it be nice to know some
thing about the noise?  Is there a big peak at 360?  how broad is
that paek 5hz or 20hz?  I would expect the power spectrum of a
hum to have multiple peaks.

Get a spectrum analizer.  

Software will do it.  Record the humming connetion to a file
and then run it through software that plots a power spectrum.
THere is plent of good open source software.  Even some audio
file ditors have this feature.  You should be able to see the
hum as periodic peaks at the multiles of 60hz.  You can't even
begin to talk about how to fix this without such a plot.

 My first thought was an RC filter, too. But I'd suggest that 500 Hz
 is too
 high a cutoff, because a note like a middle C is 256 Hz. I don't
 think
 it's uncommon for a voice (especially a male voice) to be in that
 range
 frequently. Although (in English, at least) vowels generally have a
 low
 frequency and sharp consonants (like a t) have a high frequency. It's
 the
 consonants which do the most for understanding a word, so maybe
 having
 those low frequencies attenuated wouldn't be so bad after all.
 
 But as somebody else pointed out, a first-order RC filter probably
 wouldn't attenuate quickly enough. By the time you get into a
 multi-order
 filter, it's probably best to be doing it in software (since the
 signal is
 going to be digitized anyway).

Re: [Asterisk-Users] Budgetone phones from FWD

2004-02-18 Thread Chris Albertson


It says good things about them that they've not charged you yet.

I ordered a blue phone and had to wait.  they kept offering me
a black phone now but I said I'd wait as I didn't have time
to test the phone and part of the test was to see if the blue
was a good color.  I finally accepted thier offer for a
black phone and only then did my CC get charged.  FWD was
very respponive to e-mail.  The order arrive two days after
I sent mail saying OK send the black one  I noticed they
removed blue option from the order form.

You might complain about the quality of the GS phone but not
FWD's service.  But they DO seem to have a problem getting
these phones.  It appears GS just can't build them fast
enough to keep up with demand.

Re: [Asterisk-Users] Howto apply a patch, diff file

2004-02-17 Thread Chris Albertson

You use the patch command.

You can read the patch man page by typing man patch
there are many options like for example to
Save a copy of the original.

It is also good to read the patch file before you apply it
to get a feel for what will be changed.  A patch
file is simply a set of editor commands to be applied.

Have you seen festivox?  It's a tool for building voices

The key to making festival sound natural is to get the
timming and entonation right.  The astrisk app uses festivels 
demo test to speech application which is just that a
quick dirty demo. 

Have you seen the markup language on the CMU site?

Sable can do MUCH better then the simple tts application.

RE: [Asterisk-Users] Dialing 800 numbers with VOIP

2004-02-10 Thread Chris Albertson

I think the please try your call again later part of
the recording is to be taken seriously.

I've tried 800 numbers and failed but I tried re-dial several
times and it worked after a few attempts.  I have no idea how
my call is routed but I'd not be supprized if NuFone, Iconnect
FWD and the like don't just have a small number of POTS analog
lines for the outbound toll free calls and you simply have to
be lucky to call when one of those is available.  It may not be
exactly that but I'll bet there is n of something and you are
the n+1 caller.

What you can do is put backups in the dial plan so if, say FWD
fails you go for the next service in line.


--- Tim Petlock [EMAIL PROTECTED] wrote:
 Hm.  After seeing all the people who say it works, I thought - maybe
 I
 forgot to dial 9 in front of the number and that's why the call
 failed.
 
 So I looked up the Wells Fargo toll free number again and tried it.
 Failed.  SIT tones and We're sorry, your call did not go through. 
 Will
 you please try your call again later?  The recording has nothing at
 the
 end that might give some clue who was generating it either.
 
 Okay, I thought, maybe it's a regional number and that's why.  
 
 Nope, for further testing I looked up toll free numbers that for sure
 would be nationally dialable.  They fail exactly the same way.
 
 Perhaps it's something in my Nufone account setup?  I don't know. 
 The
 SIP and IAX debug messages on my console don't look appreciably
 different from those where calls complete so I know the call is
 getting
 there.
 
 It's impossible for any recording to be generated on my * box because
 my
 sound driver has yet to work, it's not coming from there.
 
 I'm certainly not out to bash Nufone - I live in Uruguay and have a
 64k
 internet connection.  Vonage barely works because the codec they've
 chosen and the speed I've bought don't match up.  (I imagine that it
 would work better if I had a 128k connection - but 64k is USD$42 per
 month and the providers prices increase exactly proportional to the
 speed you want.)  There was about a 1.5 second delay in the other
 party
 hearing what I was saying and only one person could talk at a time.
 Using a different Cisco ATA to connect to * and then GSM over IAX to
 Nufone sounds night and day different.  No delay, minimal distortion,
 two-way conversation - this is good stuff.

RE: [Asterisk-Users] NIC card failure [was: System freeze]

2004-02-10 Thread Chris Albertson

VOIP is a very low data rate compared to the bandwidth of
a switched 100BaseT network.  Lets say you are using 100BaseT
to trunk 100 simultainous calls at 64Kbps (How many of us really 
would ever do that?) 100 calls would be 6,400,000 bps.  Well
over what a T1 could handle but is only 6.4% of 100Mbps. or
maybe 25% of the usable bandwidth of a switched 100BaseT
segment. (Ethernet does not work well when loaded over 30% of
it's nominal bandwidth.)

Think of it another way 100BaseT is 100Mbps.  If 100 calls
are on the line each call gets 1000Kbps  So VOIP in an office
enviroment does not even come close to pushing the limits of
Ethernet.

Things like NFS and HTTP cascing with SQUID are much harder
on a network and may push you to things like using gigabit
ethernet but voice is a comparitively low data rate.

How to select a NIC to use under Linux?  Read the drivers.

Pick the NIC with the best driver.  Even a quick scan over the
comments will let you see how much of the NIC's hardware is
being put to use.  Are the bytes being read one at a time with
programmed IO?  With DMA?  Is there a hardware ring buffer being
used?
How about packet filtering on the card?  Take a look, the Reltek
is not a bad choise.

RE: [Asterisk-Users] Dialing 800 numbers with VOIP

2004-02-10 Thread Chris Albertson

I second the last comment below.  I  sent $5.00 via pay pal
to NuFone and was up and runing very quickly.

My problem is billing.  What you do is send e-mail asking 
How much is left in the account? and then if it is low
you send more.  For test purposes this is not bad but I
can't imagine setting up an end user with Asteisk and them
explaining to them that for the rest of their life they will
have to send account frequent ballance inquerries to NuFone.

I could be wrong and maybe I'll get billed when my $5.00 runs
out.  I started with such a low amount just to see what happens
when it runs out.  Will there be an outage of service?  Is
that how I will know I'm at zero ballance?  Maybe I'll get some
e-mail or a voice message saying You're low, pay up.
I guess I'll find out.  But without a good billing system it
can't be used in a small office that employs no phone geeks who
will track ballances.

About thier rates.  Not bad.  You need to ask and you'll get a
spreadsheet with the per minute rates.  They beat Iconnect by
a slim margin. BUT they talk IAX2 which is a big plus.

Why is this not on the web and automated?  My guess is either a lack of
devlopment resources at NuFone or he's more interested in supporting
high volume customers who don't need a web site but more likely both.

 There are no fees.  Think of it as a calling card.  You put $10 into

Re: [Asterisk-Users] The Smallest Asterisk Server Ever?

2004-02-03 Thread Chris Albertson

I read a report of Asterisk running on a Microsoft X-Box.
That's kind of a stunt as you could buy a decent PC for
the price of a Linux-capable XBox.  Id's still like to
see Asterisk run on very low-end hardware

The Snom IP phone runs Linux inside?  I assume as Linux
is GPL'd Snom will supply the source code?  It would be
fun to install an Asterisk server in a phone.

because my name started with A which put me at the top of
the white pages listing and as I'm always on line I get
to be the top of a lot of lists.  But Adamson would be
above Albertson unless Adamson is unlisted

Now, I'm noticing that I have both Sue Albertson and
Chris Albertson listed and it is Sue who gets 3x as
many of these calls.  

Now I'm curious why some people _don't_ get these calls

I'm in the FWD white pages.  Are you people who don't get
these calls unlisted?  If so that would explain it.

Does your system send incomming FWD calls to voice mail.
If not them you'd only notice a junk call if you hear it
ring.

Would you tell us something about the before and after setups?
What was it that you did.

Some of us who run mailmain list servers might want to know.

Re: [Asterisk-Users] asterisk with big number of extentions.

2004-01-29 Thread Chris Albertson

Aside from the search time, which appearently grows linearly
with the number of extensions, you have to worry about
volitility in the list of 25K extensions.  Lets say that
every two years on average one of your uses changes.  I think
that means you will needs to make three changes a day.
So you will be editing extension.conf and doing a reload
a few times a day, every day. With 25,000 users will there
_ever_ be a time when no one is using the system so you can do
a reload?

You will need some why to modify the dail plan without taking
the system off-line.or you will greatly upset a lot of users.

And while you are in there, it should not be hard to improve the
search time better than O(M=N) at least for non-wildcarded extensions
A simple binary search will
get you to order of log2(n) which is a big deal with N  25K

  No problem, as long as none of them make any calls. 
 
 The number of extensions is relevant. I am not
 sure the level at which begins to matter, but the
 comment reproduced below from pbx.c gives some
 idea that eventually it may be an issue worth
 considering. It may be that at 25k extensions 
 the O(N+M) search starts to become noticeable.

Re: [Asterisk-Users] asterisk with big number of extentions.

2004-01-29 Thread Chris Albertson

 What are you talking about?  You can already reload the dialplan
 without affecting existing calls.

Thanks,  Now that I know it can be done, I'm sure I can
figure out how.  I just figured that a re-load zapping a
media stream going through Asterisk is just normal and to
be expected.  Din't even think about it being either a bug or
operator error.  

But for my use this is not important as at most I'd be running
a small office with ~10 lines were people go home at night.
But with 25,000 active users ...when convenient would be a long,
long time.

Re: [Asterisk-Users] Re: Grandstream 100 sidetone

2004-01-28 Thread Chris Albertson

Stephen I think hit it on the mark.  I could not figure
out how sidetone could be heard as an echo and how it
could be loud.  On my GS phone the sidetome is very low
but with zero delay.

The best way to test the side tome is to talk to the
voicemail or record application running on a local
Asterisk server.  Record does not send audio back
so anything you e hear is real sidetone.  I find
it to be decent quality but to low in volume.

 If I'm not mistaken, what you are calling sidetone (the copy of your

Re: [Asterisk-Users] Zapateller

2004-01-28 Thread Chris Albertson

I have a few (more specific) questions about 'Zapateller':

1) How would you test this??  Would I need a predictive
dialer machine like the telemarketers use.  OK, I could
just wait and see if it seems to cut down the unwanted calls
but that's not really a test.  


2) I don't understand how I would choose to use the
answer option or not.  under what conditions would
answer by better then not using the option?   I asume
if I used answer the tones would play in caller's ear
and be _very_ anoying to them.  Why would I want to do that?
There must be some reason are why would the option exist?

[Asterisk-Users] Junk calls from FWD numbers

2004-01-28 Thread Chris Albertson

My Asterisk server registers two FWD numbers.
On average I get about one call a day from someone calling
from an FWD number and leaving a pointless, under 10 second
message.  It's easy to see who these people are if I look
in my CDR file I can see thier name and number.  They seem to
be new FWD users, likely who've just downloaded FWD's Xten
softphone and then dial some random FWD user (me) to try it
out. I wonder if these same people when they first got a
POTS phone installed in thier home got out the white pages
and dialed randomly asking anyone who'd answer Hi does this
work? can you hear me?

Question:  Does everyone with an FWD number get these junk
calls or am I the only lucky one?

Re: [Asterisk-Users] Has Nufone gone belly-up

2004-01-25 Thread Chris Albertson
I think discussions about which VOIP service providers are best
or not best is a reasonable topic for an asterisk user's
list.  After all, selecting a provider is a big deal 

Rants about some company just make the rant-er look bad and
should be avoided.

Back to NuFone.  I've just started testing thier service.  So far
so good.  The sound quality and pricing is very much like Iconnect
but NuFone will accept IAX2, a big plus.

But my e-mails are ignored.  Actually sending e-mails was part of
the test of this vendor.  I'm testing to see if they answer e-mail.
So far, not good.  Maybe NuPhone needs to loosen up their spam
filters or at least scan the spam folder every few days.

  I am not here to tarnish Nufone name but I have no option but to

RE: [Asterisk-Users] Standalone FXO device

2004-01-22 Thread Chris Albertson

  I connect with the Clipcomm device, my DSL gets down and it gets up
  only when I switch remove the line from the device. I dunno what
 kind
  of problem it is.

With DSL one line shares voice and data.

_Every_ device plugged into your phone line except your DSL
modem needs an in-line filter.  The filter prevents the non-modem
from either changing the line impedance or putting high frequency
noise on the line, either of which will kill the DSL signal.

So if you plug an FXO device into the same line that also carries
DSL and don't use a filter the FXO device could very well kill
your DSL connection.  But it all depends, some times you can
skip the filters.  I did but then I plugged in one more analog
phone and broke DSL.  I installed a few in-line filters and now the
DSL works better.

If you did place a filter between the clipcom device and the rj11
wall jack then something else is going on

Have you ever set up mailman on a Linux system?  9,000,000
would be a real trick setup not something you'd do with a
standard PC.  You have a rack full of mail servers, raid disks
and the works.  Lets do some math:

 There are 60*60*24 seconds in a day 9E6 per messages/day
 means a little over 100 messages per second sustained 24x7.
 I really doubt it.

I think nine milion is a technicl term just like sh*t load

RE: [Asterisk-Users] Digium X100P for $43

2004-01-21 Thread Chris Albertson

Pirated??  I don't think Digium makes the X100P cards.  They are
common cards sold under several brand names Digium being just
one of the names.  The selling price varies dramatically depending
on the re-seller and which brand name is on the outside of the
box.  What Digium does is bundle in one hour of
consulting with each card, that's why the high price.  You are
paying mostly for theconsulting time.  

 You would have to be nuts to use a pirated card. For saving a trivial
 amount of money? Stupid idea.

You _can_ copyright the artwork on a card.  (The artwork defines
path of the printed conductive traces.)  If you own the
copyright, well, you own it.  But does Digium own the copyright?

In the case of the X100P they don't.  The X100P is re-branded
comodity hardware. Of cource they all have the same FCCID number.

If they are zapata designs then the design is in the public
domain and _anyone_ may do as they please with it.

One interesting quote from the zapata web site:

These cards are currently available from Linux Support Services in
Alabama. They are now in full production, and the cards are readily
available. For information on pricing and availability, please contact
Mark Spencer ([EMAIL PROTECTED]). For those wishing to
fabricate their own cards, the gerber photoplot files may be downloaded
here.

The designers of this hardware seem to have worked in the spirit
of the open source movement and purposefully made thier CAD files
public.  I think it's great that we have an Open Source software
system that can run on open source hardware.

Actually while it says public domain on the web site.  The PDF
files containing the design say GPL.

RE: [Asterisk-Users] ADSI phone vs. IP phone

2004-01-19 Thread Chris Albertson

One other option, although I hate to suggest it but will admit to
having done it a few times...

Ethernet uses only two twisted pair.  Cat-5 wire has four pair
inside.  You can crimp two RJ45 terminals on one lenght of CAT5
wire.  It works and remains CAT5 if you keep the pairs twisted
all the way into the terminals.  OK, yes it's unclean and ugly
but the uglyness is inside the wall in back of a cover plate
and the user sees two RJ45s where there was one before.

That said, last time I got to wire a new office we pulled double
the number of Cat5 as required but only terminated it as required.
in either rj45 or 11.

You might concider using wireless for the phones.  Ether a wireless
LAN or just wireless analog phones.  Ether way no wires.  As I
remember the average cost to pull a wire ad terminate both ends
is about $100.  cheaper than a wirelass adaptor.

  Why wouldn't you just use your existing Ethernet

  number of IP phones that have builtin switch/hub that allows 
  the PC to

 Probably because it's well known that these setups are prone to

 one/both.  It also breaks switch envirenments where spanning-tree

Re: [Asterisk-Users] SER Asterisk

2004-01-16 Thread Chris Albertson

Yes, you can keep non-authorized SIP callers from accessing the
PSTN by setting up the .conf file correctly as below
but you can also
run a fire wall on the box that Asterisk runs on.  Firewall off
SIP ports except for if they come from your SER server.

This will work even if Asterisk is broken or misconfigured.
Security sould always be applied in multiple layers:  use both
a belt and suspenders

I like the shorewall firewall script.  configuration is
conceptually easy it uses the cisco-like idea of zones.

Software RAID vs. Hardward RAID???

There IS no Hardward RAID it's all software the difference is
only where the software lives, in ROM on the controler card in
the RAID box or in a Linux driver.

If you go top of the line and buy a Netapp network attached storage
box.  It thin it is just BSD running on Intel hardware but all
closed up so it looks like a turn key system.

Same with Sun.  Thier hardware RAID has a SPARC CPU in the raid box.

For Asterisk all you would need is a simple disk mirror at most.

Re: [Asterisk-Users] ultra-cheap asterisk box

2004-01-15 Thread Chris Albertson


I'm looking to do about the same thing, build very low cost
systems.  (I'm looking at putting Asterisk at some
non-profit organizations.)   but one thing you can't make
a compromise on is reliabilty.  It has to work and keep working
for years to come.  I was able to keep the price of a new PC
to about $300 ad still use an ASUS mainboard and an AMD XP2600+
The trick is to add absolutly nothing not needed.  No floppy,
no CDROM so you can run off a 200W P/S.  Next I'll experiment
with a notebook sized IDE disk drives and to see if _underclocking_
the CPU reduces it's power comsumption enough that we can save
one fan.

Ideally Asterisk will be ported one day to Linux/ARM or some
other very low cost platform.  for VOIP you do not need the
PCI slots.  In theory Asterisk could run on a Lynksys router
box with re-flashed EEPROM.  After all Lynksys' latest wireless
router runs Linux inside

Low cost to me means low total cost of ownership  To get this
I don't think buying the lowest priced parts is the way to go.
I want quality mainboard, and a quality power supply and, this
is importernt:  A low internal case temperature.  for this reason
I'll spend the extra $50 to go with Antec cases and ASUS mainboards
over the generic ones.

What I'm finding is that the PCs are so cheap that the cost of
electric power to run them is now a large part of the cost.
(assume 0.20/kwh times 200W times 365 days = $350.  So you
pay for the PC again every year in electric power to run it.
Worse.  In an office with airconditioning _all_ of that PC's
200W goes to heat and your A/C unit will use about 220W of
power to remove that 200W of heat.)
and at a small office they will not have a server room so noise
from the fan is an issue.

 For fxp0, the internal interface although the nic can do full-duplex
 it

Why do you think it is running simplex.  I read the above and see
where it says (100baseTX full-duplex)

I don't think 10BaseT can run full duplex.  I could be wrong but
I don't think so.

But why does it matter?  A single VOIP connection will not even
use 1% of a simplex 10BaseT.  Simplex 100BaseT should be able
to handle dozens and dozens of calls



 Same for xl0, the external interface. It is running 10BaseT but again
 it 
 is simplex.
 
 Does that affect my voip performance? Is it true that every step of
 the 
 way the network has to be full-duplex?

If the former, that's odd.  But you should expect the later.
Linux is designed such that it will always try to put almost
all of your memory to good use.  It will use extra RAM as
a disk cache.  So if you were to cut the amount of RAM in
your system in half you'd have only slightly less free RAM
as Linux would use a smaller disk cache

Now if you say the Asterisk process in the idle state is
450MB then something is wrong

 Referring to my previous post about degradation of voice quality when
 
 having more than 2 connection.
 
 The actual route is:
 
 pc xlite - local asterisk box - iaxtel - local asterisk
 
 I have tried out a different situation:
 
 pc xlite - local asterisk box - iaxtel
 
 and the second connection
 pc xlite - local asterisk box - iaxtel - local asterisk
 
 The same degradation happens as soon as the second connection is
 connected.
 
 I am suspecting the ADSL connection. The internet part is ADSL with
 512k 
 down and 128k UP. The nic is a 3c905c 100baseTX and connected to a
 NEC 
 ADSL modem.
 
 # ifconfig xl0 
 
 xl0: flags=8843UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST mtu 1500
   
  address: 00:01:02:78:11:e8
  media: Ethernet autoselect (10baseT)
  status: active
  inet 203.219.167.126 netmask 0xfffc broadcast
 203.219.167.127
  inet6 fe80::201:2ff:fe78:11e8%xl0 prefixlen 64 scopeid 0x2
 
 But ifconfig seems to suggest that it is running in simplex mode.
 
 Is the degradation a result of the ADSL connection?

The fact that you 10BaseT is simplex will not matter as 10Mbps
is 20X faster than even the ADSL's downlink speed of 512kbps

You bottle neck is the 128kbps uplink speed.  You'd think that
is a lot but you can't got say codec X uses Y bits per seciond,
so two calls are 2Y bps and keep adding calls untill your
128bps is full.  It don't work that way.

Think in terms of _probibilities_.  Say your uplink is one
quarter full.  What does that mean?  It means it is running at
128kbps 25% of the time and zero 75% of the time.  So if
an audio packet is placed on that line there is a 25%
chance it will be delayed in an outbound queue.  It is
those delays that you hear.  Actually the amount of
delay is a distribution and what you hear are the tails of
the curve.  (i.e. there is a 25% change of a delay then
there is a 12% change that two packets back to back will
be delayed, 6% of three and so on.)
With one audio stream there is no competition
for the uplink.  Adjusting the packet size can have an
effect.  Very long packets are not good

Re: [Asterisk-Users] hardware requirements of asterisk

2004-01-14 Thread Chris Albertson

He sais sound cards so I assume he is using softphones
or possably the console phone.  But then he sais two
users making call  Does this mean four phones?  if so
and you are using sound cards how is this done?

Details please.

  I have been playing with 2 Asterisk boxes for testing purposes, it

 with

  For making cals and testing out recorded message for 1 connection
 it was 
working quite well. However, when I stressed it a bit with 2
 users 
  making calls, we started to here voice degradation and cracking
 noises. 
  However, top shows cpu is 94% idle. I am suspecting the network.
 However 
  it is 100M switch and I have not had any clue. I suppose it should
 at 
  least be able to handle 10 calls similtaneously for even a small
 office. 
  So what is the recommended spec for 5 users or 10 users?
 
 Without any other factual detail, best guess is half vs full duplex
 problem
 on one or more of the devices (phones, PC, etc).
 
 Assuming you're using sip phones for testing (and we really don't
 even know
 that for sure) and depending upon exactly what parameters you've
 applied
 for each sip phone definition within asterisk, calls between phones
 are set 
 up by asterisk. Asterisk then instructs the two phones to communicate
 between 
 themselves, and bows out of the audio session. So, if you really are
 using
 two sip phones, then you have a networking problem between those two
 devices and not with asterisk.
 
 For anyone to offer suggestions, you really need to provide more
 facts.

Re: [Asterisk-Users] Re: failover (was Re: voicepulse)

2004-01-14 Thread Chris Albertson

I'm having the same concerns.  What we REALLY need is the
ability to test the exact nature of the problem.  OK We could
use SER to front end SIP calls but Asterisk should report
the problem and allow the dial plan to test it.  It's a
needed missing feature in *

What about AGI?  I don't know much about AGI yet but it may help
solve this problem.

--- Matt Lawson [EMAIL PROTECTED] wrote:
  But this is not to say _you_ can't built a reliable VOIP based

  extensions.conf to fail over if one service fails to
  connect to dial via the next one and finally if both fail
  use pstn. your users will see a system the just works.
 
 Now there's an idea.  
 
 I'm playing with this now, but there's at least 1 case I'm having 
 trouble recognizing:
 
 The call connects but then drops due to unauthorized.  It then only
 
 goes to the h extension and I don't get a chance to try again.  Is 
 there anyway to detect this?
 
 
 I have to cover all of the following cases:
 
 
 1.  VOIP IP address is not reachable.  Goes to extension n+101 (seems
 to 
 work as expected)
 
 2. VOIP service answers but refuses with call with unauthorized. 
 It 
 just goes to the h extension  Is there any watch to catch this 
 failure?  Perhaps put a timer on it and say if the call was less than
 5 
 seconds or something try the next one?
 
 Yes I am using a correct username and password and getting this today
 
 (not from Voicepulse, from another provider).  But there's also a 
 moderate chance that during our systems' setup a name or password
 could 
 be misspelled so I need to cover this case.

If your providers requires a pre-paid account the the account
bvallance runs out then I gues you'd get unauthorized.
So this could be a real case that will happen

 
 3.  VOIP service connects but reports all busy.  Well this one is
 hard 
 to test.  But I can make the Zap channel busy.  It goes to extension 
 n+101 as expected, so I'll have to assume that a busy VOIP service
 does 
 the same thing.

I get this from the stwo VOIP providers I use about 20%
of the time.  I guess they have only so  much gateway
hardware.  Normally a quick re-dail does it.
 
 I was trying to determine if the t or h extension would be useful
 
 for these but I think not.  The timeout has to be set long enough for
 
 someone to actually answer (20-60 sec or whatever).  The h is
 always 
 visited at the end of the call, whether it was sucessful or not.
 
 Any other cases, or suggestions how to handle case #2?

Re: [Asterisk-Users] How do we updated to the new .7.1 version.

2004-01-14 Thread Chris Albertson

Step #1.

Go to your local landfill or dumpster and aquire another PC.
Any old junker will do.  Install Linux on it.  This will be
your test machine.  (Seriously, you'll want at least a 200Mhz
Pentium class box with about 128MB RAM and a 5GB drive.)

Use the test machine to try out stuff.  A mistake on the test
box will cause no harm. Never do development or test on a
production server.

Step #2

Assuming you've set up thre test system.  Build the new 7.0
code just like you did the 5.0 code.  the make install will
overwrite the old stuff with the new stuff.  If you have
any problems post a _specific_ question to this list.

Re: [Asterisk-Users] Best Linux Distribution

2004-01-13 Thread Chris Albertson

I have to agree with the below but only if it is an answer
to the limited question of Which is best to use for my
Astrisk server.  For a server you are using such a small
percentage of the Linux distribution that they are effectivly
all the same. 

A server will not make us of any of the graphical interface or
Desk top software.  Most * servers run with no keyboard or
CRT plugged in.

BUT, If you are running an Asterisk server you will likley
also have a Linux box for development, testing and general
e-mail and web serfing.  For this purpose it does matter, a
little.  They all will do the job but differ in terms of the
details of exactly what software is included and how the menu
system on the desk top is set up.  Still none is better but
they are differntent enough that people can have strong
prefference.  

The differences between distributions are minor.  I doubt
an inexperianced user
could tell this Solaris 9 box I'm writing this on from a Linux
system.  Both run gnome and look the same on the surface.
But Linux and Solaris are far more different then any two Linuxes.

That said, pick a desktop system you like.  You can get a free
download of any of them or low priced CDs at cheapbytes.com
and try them out.  Then use the same distribution for your
server.
 
 They're all just Linux. There is no best. This question is asked so
 
 frequently it almost looks like a troll to me. :)
 
 I've therefore updated the FAQ on the wiki:
   - http://www.voip-info.org/tiki-index.php?page=Asterisk+FAQ
 
 Which Linux distribution should I choose for Asterisk?
 --
 There is no best distribution. There are no fundamental differences
 in 
 functionality or behaviour between Linux distributions like there are
 
 between versions of Windows. Pick whichever one you feel most 
 comfortable with.

Re: [Asterisk-Users] Asterisk 0.7.0

2004-01-13 Thread Chris Albertson

I think the exchange below shows us that before 0.8.0 comes
out, maybe there should be a 0.8.0-beta then after no problems are
reported in a few week period a 0.8.0-release candidate and 
ten 0.8.0 itself.

It's hard to call a realease stable until a number of people outside
the developer's lab have used it for a while.

The other idea is that everyone just knows that x.y.0 == beta
and they all wait for a .1 or .2 realease.

[Asterisk-Users] How does the PSTN termination indurty realy work?

2004-01-13 Thread Chris Albertson


Does anyone here understand how these VOIP/PSTN gateway companies
work?  There seem to be a number of small outfits that offer about
the same service.  I'm thinking that a company that is really just
one person and a web site can't possibly own and operate gateway
equipent in 100 contries world wide.  I figure there must be some
large outfit who _does_ have physical equipment installed in 
hundreds of locations that leases time to re-sellers like
Nufone, Iconect, Voice Pulse, Addaline, xvoip and the others

If this is realy how the industry works, then does it matter which
retailer you pick?  Matter in terms of audio quality and reliabilty,
this is.  I know each will have it's own customer support and
pricing.


 This on the heels of switch-1.nufone.net being missing out of DNS.
 
 We have customers that expect their VOIP to work.  Is there anybody
 that's reliable?

 anybody else

A company should be able to even stay on the air if there is a

[Asterisk-Users] VOIP-PSTN service recomendation?

2004-01-12 Thread Chris Albertson

I'm looking for a service that will accept VOIP calls and
send them to the PSTN.  Or, I should say _another_ service
that will do this.  I don't need the other direction

Currently I'm using IconnectHere and it works, but I get
complaints of poor audio quality from the other end.  But
it sounds OK on my side.

I like Iconnect's price model: very low/no monthly fee with
a samll per minute charge.  I'm in US 310 area code and call
to US, Japan and Canada.

Who are Iconnect's competitors?  Anyone want to recommend
a service?

Anyone who does not like the fact that all code must be
disclaimed, sent through Digum to CVS and that GPL'd
code can't go in can fix that problem.  All you need to
do is copy the current CVS and use that to start your
own project.  You can call it Asterisk Prime or Star
and make up your own rules within the limits of the GPL.

So there, if you want the rules changed _you_ can change
them.  But I'll bet you don't want the rules changed so badly
that you would go to that much trouble.  I and I assume

[Asterisk-Users] IConnect audio quality

2004-01-09 Thread Chris Albertson


Hello,

I've subscribbed to IConnect.  I use it eclusively for outbound
calling.  I like the rates they charge but people I call complain about
the audio quality.  They say it sounds like I'm using a cheap mic. or
they
complain about echo.  The sound is very clean at my end.  I'm using
a Bundgtone phone with meadi routed through Asterisk to IConnect.
It's not the BT100 phone as the Audio is OK in cases where I don't
use Iconnect.

Question:
  What service (other than Iconnecthere) should I consider  moving
  to?  Here is what I want:

  * Acceptable audio quality 
  * Take outbound calls from Asterisk to PSTN
  * I do NOT need a did. (no need for incomming calls)
  * I prefer pay as you go with little/no fixed monthly fee
  * They need to provide call termination to PSTN in the USA,
Canada and Japan
  * Price maters but is secondary after the above

[Asterisk-Users] Re: [Asterisk-Dev] benevolent dictatorship, or inclusive developper community?

2004-01-06 Thread Chris Albertson

What hapens in other Open Source projects is that someone
gets _really_ frustrated and also happens to have some free time
so he copies the current code into his own CVS system and runs
with it.  If he does a good job user follow.

I imagine that if someone were to take the current code, apply
all the patches there are out there, test it with a beta program
and then documet the features no one would bother using Digium's
CVS system any more - they'd go for the stable tar file.

Most people I think feel it is easier to put up with the current
situation then to step forward the take on the job of doing it
right.  It would take a lot of time.

I can envision someone wanting to run a company that did mostly
Asterisk consulting wanting to take on this job.  being the place
everyone goes to get the slick-packaged Asterisk code would get
them a reputation and a leg up on the other Asterisk consulting
companies.  But as above, It would take a lot of time.

Re: [Asterisk-Users] sendmail problems

2003-12-23 Thread Chris Albertson


You say The server crashes  I assume you mean that Asterisk
core dumps and sendmail continues to run just fine.  If you
can send mail out of the box sendmail is confgured well
enough and I doubt the problem is there.

If you can get Asterisk to dump then what you need to do is
use a debugger to get a backtrace.  This will tell to the
line (as i line of coe) that caused the crash.  The thing to
remember to that if a program crashed it is due to t bug..
There _should_ be no way for a user through misconfiguration
to cause a core dump.  What you are looking for is a little
bit od C cde that doesn't handle some condition well.  If yu
use gdb and the bt commad you can find the line 
Asterisk was executing when it crashed.

I'd not suspect sendmail

Re: [Asterisk-Users] PBX Functionality How-to

2003-12-23 Thread Chris Albertson

One thing Centrex is that Asterisk is not is a turn key
system.  With Asterisk you have to either build the PBX your
self or pay someone to build yu one.  With Centrex you
simply write a check.

THat said, you can build  anything you want so of cource the
feature list can match.

The best way to learn what it can do is to build a small PBX
with just a couple extensions.  Try to build in all the
funtionality you need in your larger system.  

If you get into trouble you may want to ask __specific__ questions
like I want to make XXX work, I triedd XXX and YYY but I still
have this problem it it?   You may have to post 50 questions
like that one at a time.  But you will get answers.  Asterisk has
a learning curve.  expect it to take a few weeks of study

But the bottom line is that Asterisk will do quite a bit more
than Centrex.  I don't think Centrex does VOIP at all

Re: [Asterisk-Users] Auto Starting Asterisk

2003-12-23 Thread Chris Albertson


Look in the directory /etc/init.d (/etc/rc.d/init.d on
some systems)

You put a script in there called asterisk.  There is a
sample called asterisk.init in the source.  copy it to
/etc/init.d/asterisk

You may want to study the other files in /etc/init.d to see
how they work. 

Next read the chkconfig man page  and  see way you'd want to
type chkconfig --add asterisk; chkconfig asterisl on

Finally to start asterisk you can type ./asterisk start
You may also want to re-boot the computer to verify that
asterisk does start automatically

Re: [Asterisk-Users] Asterisk SIP Packet Time (20ms)

2003-12-23 Thread Chris Albertson

The reason you use UDP over TCP for realtime meadia is that
TCP's ability to reliably deliver every packet in order actually
sounds worse.  Reason being is that with a UDP system a dropped
packet sounds like just a dropout but if you used TCP the audio
stream would be held up and delayed in a queue while that lost
packet was being retransmitted.  In stead of a dropout the audio
would sound as if someone kept hitts a pause button on a tape
recorder.  A dropout sounds better then a delay of potentialy 
several seconds

Almost all realtime meadia systems (telephony, video, possition
reporting and so on) maintain some kind of a buffer on the recieving
end.  But you trad the buffer lenght for delay.  Using UDP allows
the application to do the buffering where as TCP putting this buffing
functin in the operaing systems network code.

I think this is a problem on the Asterisk side.  I'm seeing
the same problem using a Grandstream Budgetone 100.  And the GS
does have setting for both in-band and RFC2833.

My guess is asterisk is accepting the DTMF tone __both__ ways
It is reading the RFC28833 stuff _and_ hearing the audio tones
as well.

 Changing the DTMF mode would indeed seem to be the logical
 solution.  However, it appears that SJphone does not support that

There are no issues.  There is no reason to have a K/B or

global warming.  You may also want to pull any CDROM or

Seriusly, you should be using ssh from a remote machine to

RE: [Asterisk-Users] fedora core 1 install problem - CAN SOMEONE ELSE HELP HIM

2003-12-18 Thread Chris Albertson

Reinstaling the OS is not going to do anything ut get you
right back to where yu are now. 

Look at the last command the the Makefile tried to run.
Did it choke while running bison?  If so run the bison
command by hand.  What happens?   You need to cd to
the directory where Makewas at when it tried to run bison
first.  

You might also try typing which bison just to verify that
bison is installed and in your path.

In general when a Makefie fails you try to get the failed
command to run by hand and then you fix up the Makefile to
do whenever you neede to do by hand.

Re: [Asterisk-Users] SIPURA Breaches Contract

2003-12-12 Thread Chris Albertson


Does this kind of stuff really belong here?  Heck for all
we know you guys did something dumb to make them mad at you
and they had good reason for their actions.  

 Who knows, why should we care??

Someone here said you guys charged him _prior_ to
shipping an item.  If anyone charged me in advance
of shipment I'd blacklist them forever.

Again who knows what's up but the bottom line is one
sided rants and self defeating.  No one cares who's right
no one was any why to know either so arguemts are
pointless.

 Hi list, 
 
 Well I really didn't want to see things get to this point,
 but Sherman at Sipura along with their President Jan F.
 leave me no other choice.
 
 SIPURA has been provided a letter from our attorney for
 Breach of Contract and damages.  They have yet to respond.
 
 A quick background.
 
 1. Sherman (SIPURA's Director of Marketing), stated that
 we would do a join press release for the Oct VoIP conference
 in Long Beach.  The day the release was suppose to go out,
 he decided not to do it. We had agreed to pay of half of the
 cost to get the release out.
 
 2. SIPURA and Chagres negotiated a contract, where Chagres was
 to provide logistical support for sample sales of the SPA-2000.
 This contract was executed by SIPURA's President Jan F.
 
 One day after the contract was mutually executed, Sherman from
 Sipura, stated that instead of having us do the logistical support
 they would handle this within the company.
 
 The following day, I was advised by several ASTERISK list members
 that SIPURA had a company listed on their website doing order
 processing.  They asked if this was the new company we where
 forming to handle the VoIP hardware.  Upon review of both SIPURA's
 site and the other company it was clear that SIPURA had sourced
 this service to another firm, AFTER IT EXECUTED A LEGAL AND BINDING
 contract with us.  Chagres spent considerable time and money 
 putting into place the requirements outlined in the contract.  Those
 efforts are now lost money
 
 3. In conversations with SIPURA's President Jan F. he committed to
 having product available for us to pickup in Hong Kong on 1-Nov-03.
 When we contacted Sherman on 4-Nov to confirm pickup, Sherman would
 not commit to the order, pickup or anything else.  All he wanted was
 for us to pay them the money for the equipment and then we can
 talk.
 SIPURA's President Jan F. has not returned any further phone calls.
 
 4.  Sherman had agreed to provide us with leads for 50 some odd
 different
 companies that where looking for SPA-2000 product.  When we asked him
 again for those leads, he refused to provide them.
 
 
 In general, I beleive that the actions of SIPURA and its managment
 team have been less than honorable, they have damaged Chagres and
 have hurt our customers.   
 
 Sipura has a simple and clear path to resolve this matter.  Honor
 the contract they signed with us.
 
 SIPURA has also further breached their agreement with us by removing
 us from their Partners page.
 
 
 I remain hopeful that SIPURA ownership and management will see 
 the honorable course of action and live to the terms of the
 contract we executed.  Should they decide to continue to ignore
 us and our attorney's attemts to communicate we will take legal
 action in court.
 
 
 Sipura has a GREAT product, its sad to see that their management
 team is willing to breach contracts.
 
 
 To our customers that have pending orders.  We have attempted to
 source inventory from another location and have not been able
 to do that.  There for we will be issueing complete refunds for
 all SPA-2000 purchases.  
 
 
 While we have been difficult to reach in November, I remain
 strong in the belief that we will do the right thing by our
 customers, and that our ability to service further (starting
 today) orders has vastly improved.
 
 Cheers
 John Brown

Re: [Asterisk-Users] Sendmail not on localhost

2003-12-10 Thread Chris Albertson


You would have to look at the code in the VM app.
and see if the hostname for the mail server is configurable.
Likely it is simply hard coded to localhost which would
send the mail to port 25 on the * sever.   In theory
the VM application _could_ use a remote mail server but it
would have to be written that way.  

I'd prefer to run a local sendmail.  Ths means you have a local
queue and the mail gets handed off quikly even if your
other server is down or slow.

Re: [Asterisk-Users] next stable release?

2003-12-10 Thread Chris Albertson

I think the word here is that stable release is a
do it yourself project.  You need to set up a test
environment where you can check out new CVS updates,
apply patches you want and see that it all works.

Only then would you but the code on a productin system.

 Also many of latest cvs additions are bug fixes,
 nothing really new, apart of cdr_odbc.

Re: [Asterisk-Users] Computing horsepower needed

2003-12-10 Thread Chris Albertson

I've set up a test enviroment and beed trying to answer that
question.   

I think if you are carfull NOT to do dumb things like
running X11 and a browser and so on on the server you can use
a pretty low power system.  Just do not plug in a CRT, mouse
or keyboard.  Use telnet or ssh.  The requirements to run
a graphic interfaceare are greater then to run a low-end asterisk
server.  Asterisk seemed to run well on am old 400Mhz Pentium
but I'm using an ADM2600+ with 128MB ram and am not taxing the
system much at all.  I think a 1Ghz Pantium would be well
more then required.

OK that said.  BIG remaining question.  I've got some echo
problems with the FXO card.  Fixing this might take a lot of
CPU power to do the required DSP.  I don't know yet.  But
it works with two calls open at about 2% of the CPU utilization.
ond the ADM 2600+
Pushing 8K sample/sec data aound is a very lightload
audo at 8K is a very low data rate.

My goal is to reduce the heat and electic power.  I may try
_under_ clocking the 2600+ and see if that makes it run cool
enough that I can remove a fan.

We assume this kind of experimentation is happing in a lab
enviroment.  Failure there is not a problem it's a data point.

In a test system I can take out half the RAM, slow the CPU clock
or run the CPU without  the cooling fan and just measure what
happens.  Yes, stupid do do those things in a system people
are depending on.

  There is a _good_ reason to ask too.  I've been experimenting
  I buy new

  120W of power if you can use a one that uses 45W and
  lets you get rid of one of the fans.  Same with disk drives.
  More RAM might let you use a low noise/low heat drive rather then
  that 7200RM noise maker.  I'd like to be able to install a
  notebook sized drive on the * server.
 
 No, actually that's a terrible reason to ask.  If you are unfamiliar
 with * 
 you have no business trying to optimize your system.  This is typical
 early 
 optimization that plagues any design or deployment.
 
 Just learning * is NOT the place to try and cut corners and save some
 coin.  
 Get it working, get familiar with it and THEN see where your specific
 needs 
 are and optimize for them.  
 
 Early optimization is a problem everywhere, not just in programming.

Re: [Asterisk-Users] Multiple Asterisk servers sharing/propagating registry ?

2003-12-09 Thread Chris Albertson

It would be a major change to the code but I think what you'd
want to do is have the Asterisk server store _all_ of it's information
in something like a database, The dail plan, SIP registrations,
everything would have to go there.  Once you've done that any
number of Asterisk servers could share the same database and there
are methods of running mirrored databases already.

When I worked at a dot.com we had a design requirement that I
should be able to go into the server room and pull any of the AC
power cords and the users should not be able to know.  About the
_only_ way to do this is with load balancing.  Fail over does
not work so transparently.

With SIP or other VOIP phones there is a chance of doing a kind of
load ballance but with an analog phone wired to a channle bank, if
the CB smokes

Good News: as far as I can tell Asterisk already does keep much
of it's data in a Barcley style DB does it not?  If so Asterisk
is 3/4 the way there.

But I think the market for this is someone with 5000 extensions
who needs five nines of reliability and Asterisk has other
things to do before it can be used for such a system. mainly
getting dail plan info out of those .conf files.

 The setup I imagine would be something like :

 - each SIP client would register with sip.isp.com (thus ending on a
random asterisk servers)
 - but after that, all the servers would be aware of the
registration. Thus any asterisk server would know how to route a
call to SIP/some registered user
 
 Same thing for IAX peers.
 
 Of course, setting up various IAX links between each server is no
 problem (with registration cascading, for instance).
 
 Registration cascading is not possible (I think) but could it be
 solved 
 with a shared dial route:
 
 Instead of DIAL(IAX/sip.isp.com) could you not 
 DIAL(IAX/sip1.isp.comIAX/sip2.isp.comIAX/sip3.isp.com) to reach a
 similar

 one, then the second one if it fails, and the third if that fails.

Re: [Asterisk-Users] FXO cards - low cost systems

2003-12-09 Thread Chris Albertson

Comments on this are welcome.  Here is my opinion...


I just went through this.  Your office size is not economical.
Actually smaller or larger would be better.  Getting a channel bank
and then using only 8 ports is a waste.  OK if you have 24 extensions
but 3x to expensive if you only use 8 ports.

I'm working on a 3x8 system for a not-for-profet  I'm doing the
work for free and they value every cent as they live off donated
money.  (You don't want to tell donors that 100 of their $20.00
checks went into a new PBX and did nothig to save sick homeless kids
or whatever.)

Here is what I told them:  Go VOIP.  You can get decent IP phones
like BT100, or whatever for $65 to $100 each.  Buy eight of these.

Next get a VOIP service provider to provide you with a PSTN DID
(A phone number) VoicePulse will do this for about $8.00/month
pluss outgoing per minute cost. So you get as many incomming lines
as you need and you have zero hardware interface at your site.
(other then your DSL line.)

Keep one or two analog POTS lines and use one or two FXO cards
either Digium other.  You want POTs for free local calls and
for 911 calls and for if the VIOP service fails or if the DSL
line is down.  But one POTS line for the whole office is enough

So now your Asterisk server is just one re-cycled PC with one
FXO card installed, nothing else.  Pretty dard cheap.

If using a re-cycled computer as the server _do_ keep
spares on site. You don't want a broken power supply fan to crash
your phone system for a day.  I'm suggesting a full-up hot spare
Asterisk server system be kept on-site.


--- Michael Rowley [EMAIL PROTECTED] wrote:
 Hey,
 
 Here is a quesion for you.  I am still battling with the phone system
 
 for my new buisiness.
 
 6 incoming lines, 1 fax, DSL.  8 phones max, will provably start with
 5 
 to save money.
 
 I was thinking of using Asterisk, but having difficulty finding 
 appropriate buisiness phones.  The Mitel 5055 is the best one I have 
 found, but the price seems to be about 400$ per phone.  $2K, plus a 
 500$ server, then how to get the 6 B1(pots) lines into it.
 
 I had thought of using a channel bank, but what a pain in the ass
 that 
 is becoming.  For one, they are expensive, and I then have to buy the
 
 T1 card for the phone server.  I though, why not go with an FXO card.
  
 I wish there was an X400P card with 4 ports on it, but, que sera.  I 
 can get them for 100$ apiece, or $50 for the knock offs on ebay, but 
 that means 6 pci slots.  Not easy, I could use one of the pci
 extender 
 boxes, but now I am worried about conflicts.  Or dialogic analog 4 or
 
 12 port cards for about 1500 to 1800$.  :(  This is getting
 expensive.  
 Part of the idea was to save some money.  The other part was to use 
 open software as much as possible, and support the FOSS community
 where 
 ever possible.
 
 Here comes the question, wait for it :)
 
 Has anyone had success with the dialogic 4 port cards, running 2 of 
 them in a server with * in a buisiness environment as stated above.
 
 I am begining to think that I may be better off just going with a 
 proprietary system and cough up the 6K and get it over with.   There 
 are a couple of solutions that will share the cat5 cable, that's 
 something.
 
 Any ideas?  Suggestions?  Does anyone know of a solution provider out
 
 there who will be able to set this up for me for the 6K the phone 
 system is going to cost me anyway?
