Re: [asterisk-users] Any thoughts on Asterisk 16.17.0 outputting FRACK refcount related messages

[Telium Technical Support]

I don't *think* it would purely volume related.  We have 16.17 deployments
with very large loads running without issue, and we also run 16.17 against
load simulators without issue.

 

In each case you have to traceback to find the cause of the problem.  For
example, a bad SBC which does not fully adhere to the SIP protocol could be
confusing PJSIP, causing timeouts, etc.  Our engineers spent a few days
tracing such a problem before we shipped a high volume system to a customer
earlier this year.  (I have NOT traced through your logs below, so I'm not
saying that is your problem)

 

There are some helpful posts here to help you trace, in the archives of this
list.  (In fact I see one responding to a question you asked 2 months ago).
Did that yield nothing?  (The response was dead on in terms of how to
diagnose).  If you share the result of that diagnosis you might get some
helpful answers.

Subject: [asterisk-users] Any thoughts on Asterisk 16.17.0 outputting FRACK
refcount related messages

 

We have an extremely busy/large customer.  They run fine most of the time,
but periodically asterisk will output FRACK refcount related messages.  It
doesn't seem to be related to the volume, because it's not breaking during
their peak times.

 

When this happens, the system becomes unstable and they have to restart to
get things resolved.

To give an idea of the instability, we have seen INVITE/Trying responses in
SIP messaging logs.

We tell Asterisk to answer via AMI, but Asterisk never sends the OK (even 24
seconds later it hasn't sent).

Eventually the other send CANCEL of the call.

 

 

We've now captured 4 different days where something like the following
occurs.

1) Is there a good way to tell if this may be fixed in Asterisk 16.20.0
(short of upgrading)?

2) Would this be something I should submit as an asterisk issue?
Unfortunately, site is so busy capturing the debug will be very difficult
(if not impossible) due to amount of data.

How might I do that ?

That's a bit bizarre.  I had first though that this might be a problem if you 
were to start Asterisk before mounting the share... Asterisk might have opened 
the message directory when it started, and then doing directory-relative file 
creation and moves.  But, you say that restarting Asterisk doesn't change the 
behavior.

On your system, are you using containers, or namespaces, or etc.?  You might be 
accidentally setting up an environment in which the NFS mount isn't being 
"seen" by the environment in which Asterisk is running.

It might also be worth checking if you can manually create files in the shared 
location when running as the same user-ID/group-ID as Asterisk is configured to 
use.  You might be seeing some sort of odd permissions-based problem.

Re: [asterisk-users] recording not working to NFS

[Telium Technical Support]

If Asterisk is writing files into the local directory that is the mount
point for a remote NFS connection, then this is not an asterisk problem.
It's a local config/network issue.

No application should be able to write to the local disk dir used as a mount
point .  So if that is what's happening, your NFS mount is not active.  Are
you using automount?

You need to dig deeper into NFS mount...it's not working the way you think
it is.

Restarting Asterisk with the mount on does not fix it.
Asterisk simply ignores the mount and writes to the local drive.
But the mount is fine, I can create a dir and it appears on the other side,
so NFS is fine.
Any idea?

Re: [asterisk-users] recording not working to NFS

[Telium Technical Support]

If unmounting makes your files appear on the NFS mount, then there may be some 
caching going on, or files not being closed (by Asterisk).  Unmounting will 
force files to close and could make them appear.

Try restarting Asterisk (with NFS still mounted).  Do the files then appear?

Hi all,

 

I've got an old server (Asterisk 13.28.0) that I'm trying to configure to
store voicemail in a mysql database. 

 

I have sip realtime working via odbc and it's been working well for years.

 

However, when I recompile Asterisk in order to store voicemail in the
database, I have problems. (That is the ONLY thing I change.)

 

The server seems to run for a while and voicemail seems to work. Then, the
server loses ALL of it's sip registrations. I have a script that I can run
to reload the registrations, but the server eventually loses them again.

 

Any ideas as to where I should start looking?

 

Thanks in advance,

Re: [asterisk-users] STIR/SHAKEN

[Telium Technical Support]

If you operate a small PBX for a business your approach is fine.

 

If you operate a large PBX, or just have lots of high toll rate calls, the 
price difference between carriers can add up to a lot money every day.  These 
operators will route their calls to whomever offers the best rate for that 
route.  

 

And that’s the problem being solved.  STIR/SHAKEN makes it tough for spoofers, 
but also tough for businesses doing LCR.  Sadly, the easier it becomes to 
implement STIR/SHAKEN (telling the next hop along the route to trust your 
identity), the easier it will be for spoofers to do the same.  I suspect it 
won’t be long until unscrupulous service providers undermine STIR/SHAKEN

I reallt don’t understand why people simply use the same operator to terminate 
your calls, which also provide DIDs for you.

 

Then you don’t need to touch this at all, your carrier will do all the 
STIR/SHAKEN handling for you, you are just a PBX customer.

And then the operator then simply limits your account to only present your DID 
as outgoing number.

 

Seems to be a unneccesary complicated solution just to have your numbers at 
company 1 and have your call termination at company 2.

So fricking unneccessary.

 

What I know there is requirements of number portability, so as long as company 
2 can handle DIDs (ergo ”own” DIDs) you should be able to move your DIDs from 
company 1 to company 2 – then company 2 owns your DIDs.

Hi Jeff.  What exactly do you mean by the 'inbound piece'?  I've spent quite a 
lot of time with the folks at TILTX understanding the framework; but I am not 
exactly sure what you mean by the 'inbound piece.

 

Greg/Doug, like many folks here, we use LCR.  So, the terminating carrier is 
not necessarily the one that issued us the telephone numbers.  So, they will 
not sign it or simply cannot sign it.  Remember that a very limited number of 
companies can actually sign the calls; the rest have to buy it from these 
'Service Providers'.  

 

And there is another situation - the company you purchase your numbers from and 
the company you place your calls through may be different and both may not be 
able to sign your calls.  Again, a very limited number of service providers 
that can actually sign your calls.  So what do you do in that scenario?  You 
have to find a Service Provider that can:

 

1.  Verify you own that telephone number(s).

2.  Sign your calls.

3.  Provide you with the technical means to do so.

 

So, that's that...  I hope this makes sense.  

 

Alex

Re: [asterisk-users] Failed to authenticate device message

[Telium Technical Support]

You didn’t post the Asterisk version, but if this is an OLD asterisk version 
then the source IP may be missing from messages/logs.

 

If you have low traffic in general then using something like Wireshark may help 
you examine any suspicious SIP packet on the PBX.  For higher volumes it’s like 
drinking from a fire hydrant, so not suitable.

 

If this is a small PBX, have a look at the SecAst product 
(https://teium.io/secast).  It’s free for small installations.  It’s an 
Asterisk security product that monitors network traffic at a the adapter level 
so it can sniff the source.  It also talks to Asterisk through the AMI so it 
can get more details of the connection/session that way.  If this is for a 
larger PBX then you would have to move the discussion to the biz list for more 
info on SecAst.  (Or email me off list)

Re: [asterisk-users] Voice broken during calls (again...)

[Telium Technical Support]

Still lots of detail missing, butlikely causes include:
1.  Egress latency (does your router/firewall support QoS, are you leaving 
headroom )
2. Ingress latency - does your ITSP support it
3. Router/firewall latency - can it keep up with the traffic and packet size.  
Do you have way too many iptables rules in your Debian box?

Between ping and traceroute you can probably get some basic stats.  Some speed 
test websites even report latency, other sites will should tracert/ping from 
outside in to you.

How about putting a phone on the DSL/cable modem directly and calling 
out...same problem?

That's a very good idea...
Could you suggest me how can I check it?
The Gateway is a Linux with Debian 9.

Really difficult to believe... If I call another VoIP-phone in my network 
(using the "internal number") the quality is excellent.

If I call my wife using the "external number", the quality is very bad...

I don't know if there was a prior email with more details, but

Latency is as important as speed.  Have you checked latency between your device 
and pop?  What about QoS at your location, and does your ITSP support/respect 
QoS?

Could problem be inside your network?  Have you tested/optimized internal?

Subject: [asterisk-users] Voice broken during calls (again...)

Hi list!

So, now I have a business contract and a technician was here to check the DSL...
Nothing found, except that for 50Mbps I need now vectoring. Really nice... A 
couple of years ago I could get 50Mbps without vectoring.
Of course, Deutsche Telekom said nothing about this change...

Well, I got it working, and now I have 48Mbps down and 10Mbps up.
I _REALLY CAN'T_ believe, that this is not enough...

The problem with many little disruptions during calls is always here.

I tried changing the codecs and changing some settings in the SIP configuration 
of the peers.
No changes...

On the Gateway (Banana PI), where the Asterisk server also runs, the load is 
about 0.50 during calls and it has a Gbps LAN.
I can't believe, the problem is here...

@all german users using Telekom: how did you configured your Asterisk?
@all: thank you for all your suggestion, I really don't know anymore what I can 
do...

Thanks

Wow! I've been *-ing for about 6 years and had literally no idea about that! 

 

I can see a way I could put it to a different use, but it seems to be a bit of 
a sledgehammer to crack the walnut of "how many current callers" compared to 
one line of (albeit hacky) dialplan. 

 

That's making me sound ungrateful. I don't mean to be!

ARA as in Asterisk RealTime Architecture

https://wiki.asterisk.org/wiki/display/AST/Realtime+Database+Configuration
https://www.voip-info.org/asterisk-realtime/

As I recall (back from 2015), you tell Asterisk which 'configuration file' 
you want to read from MySQL like this:

# /etc/asterisk/extconfig.conf

[settings]
 musiconhold.conf= mysql,vchat,static
;   musiconhold.conf= mysql,vchat,musiconhold

I have no idea if this will help, but here are the tables as I defined them 
back in 2015.

 create  table   if not exists   static
 (
   idint(11) not null auto_increment

[asterisk-users] Send message to AMI from dialplan

[Telium Technical Support]

Is it possible to simply send a message to appear as an AMI message/event,
from the dialplan?  For example

 

exten =>123,1,ami(myEvent, param1, param2)

 

and in the AMI a message appears like:

 

Event: myEvent

Privilege: call,all

Channel: PJSIP/misspiggy-0001

Uniqueid: 1368479157.3

ChannelState: 3

ChannelStateDesc: Up

CallerIDNum: 657-5309

CallerIDName: Miss Piggy

ConnectedLineName:

ConnectedLineNum:

AccountCode: Pork

Priority: 1

Exten: 123

Context: inbound

Parameter1: param1

Parameter2: param2

 

 

I'm thinking about ways that I can send messages from the dialplan to my own
application which listens to AMI events.

 

Thanks

Re: [asterisk-users] CLI color prompt

[Telium Technical Support]

That means that Asterisk is not echoing the escape character (27) to your 
terminal.

Try different escape formats (octal, slash prefix, etc)

Re: [asterisk-users] CLI color prompt

Have you tried adding ANSI color escape codes?

There's lots of documentation for BASH prompt color using escape codes.  Give 
those a try.

(I haven't tried it, but would make sense)

Hello,

how can I change the color of the asterisk prompt to red ?

I read in the wiki that I can use %Cn[;n]

https://wiki.asterisk.org/wiki/display/AST/Asterisk+CLI+Configuration

But what does this mean ?
There is no example how to actually use it.
where do I put it?
What syntax is that anyway?
How do I specify red ?

I currently have this in my environment:

export ASTERISK_PROMPT="[%H]: "

which changes the prompt to hostname

Ho can I make this prompt red ?


thanks,

Re: [asterisk-users] Troubleshooting load issues

[Telium Technical Support]

I assumed the spikes were within the Asterisk process.   If the spikes last 
long enough use htop and iotop to see if the spikes are outside of your process.

 

If outside the Asterisk process then there are lots of generic troubleshooting 
guides.  If within the Asterisk process (and no transcoding) then turn verbose 
way up and watch for clues on CLI when a spike occurs.

Hi,

 

I have an Asterisk box which has an IVR that plays random gsm files. The box 
has SSD's and two CPU E5-2695 v2 cpus with 64GB ram. The Asterisk CPU usage 
along with the load seems to jump around. With about 500 callers it hovers 
between 250-400% CPU (so 2.5 to 4 cores) which seems reasonable. Every so often 
the load average spikes. The idle never drops below 85%. When the load average 
spikes I see a lot of kworker threads and the CPU usage tends to (not not 
always) go up as well. How would I go about seeing what in Asterisk is causing 
the spike? The box is locked down and only takes calls from an OpenSiPS box. 
There is nothing else running on the box.

 

TIA.

 

Dovid

Re: [asterisk-users] Lightweight ODBC DB

[Telium Technical Support]

IF you use the HAAst or PBXSync solution, you can include/exclude at the table 
and database levels.  You can also use SQLite if the data is suitable (and 
these products can sync SQLite too).

 

If you want a non-commercial solution, MySQL’s log rolling may be most suitable.

Re: [asterisk-users] Lightweight ODBC DB

[Telium Technical Support]

Have you looked at PBXSync (or HAAst) from Telium?  (https://telium.io)

 

These products will sync MySQL, SQLite, plus files, directories, etc. 
intelligently.  (Differentials only) between PBX’s, reload configurations on 
the fly, etc.  No need roll logs or recover from a base in case they get too 
far out of sync.

 

HAAst will also prevent synchronizing if a node is in poor health (to avoiding 
sync’ing in corrupted data).

 

I’m not sure what you are building but this might help.  Aside from this, avoid 
block based synchronization of databases (eg: DRBD) for the obvious reasons.

 

There are Master-Master sync tools out there, but if you are trying to wrap 
some intelligence around that then you are basically building your own sync 
product.

There is no additional caching built into Asterisk itself for it. The sqlite 
library calls are directly used and their results provided.

[asterisk-users] Reload dialplan from AMI

[Telium Technical Support]

I see there is a modulereload function available from the AMI, but none of
the listed modules (on the wiki) seem to reload the dialplan.  Is there a
way to reload the dialplan through this function?  Or do I have to use the
'command' action?

Re: [asterisk-users] Asterisk - can't hear other side. Or other side does not hear us

[Telium Technical Support]

This is usually a symptom of something on the call path mishandling the session 
setup.  Check routers/firewall/SIP proxy, etc.  Likely a firmware bug is 
causing it to use the wrong IP address and passing that to the other end.

 

Even if you disabled these devices, REMOVE them from the call path (or replace) 
for testing.  Add them back one at a time to confirm source of problem.

Subject: [asterisk-users] Asterisk - can't hear other side. Or other side does

Hello,

 

This is not technical post, just looking for suggestions on what to check.

I have asterisk for long time, no updates, just maintain OS updates.

 

I use SPA504G phones

 

Very rarely and randomly when we pickup a phone - other side does not hear us. 
Call them back and all works.

 

Now I have couple people I'm talking to and it seems like very call like this. 
Someone can't hear someone.

 

Don't know where to start to troubleshoot and what to look for.

 

Thanks!

Re: [asterisk-users] Pass through registration / proxy

[Telium Technical Support]

OK - I'll have to rethink how to solve this problem.  Maybe I made some
assumptions...here's what I'm trying to accomplish:

I've been given a legacy PBX with SIP capabilities.  I need to have SIP
phones connect to Asterisk (for other features, part of the next step) which
passes the calls through to the legacy PBX.  And conversely, calls to that
extension number on the legacy PBX have to ring the SIP phone connected to
Asterisk.

Maybe proxy is the wrong word I chose.  Asterisk is something like a peer to
the legacy PBX.  I thought about setting up individual SIP accounts on the
Asterisk box to connect to the legacy PBX, or maybe a SIP trunk to the
legacy PBX (assuming it can route calls through the SIP trunk to a peer to
reach a phone).  The legacy PBX is a Nortel in case that matters.

I'm supposed to figure this out and present options but having trouble
figuring out if Asterisk would be a peer, or pretend to be many sip agents
registering on the legacy Sip pbx, etc.  I think I'm stuck at the conceptual
level.  (Still a beginner in training - but having fun learning Asterisk)

You can, but maybe you should use a sip proxy (like kamailio) for this task
instead of a back to back user agent like asterisk.

You can listen to events triggered on registration to asterisk and with
realtime intergration add the register to the PBX (or manipulate sip.conf).
This still might be easier to implement compared to (for
example) kamailio if you are new to that.

Re: [asterisk-users] Blacklist failed attempts

[Telium Technical Support]

If this is a home system, try the free edition of SecAst (www.telium.ca/?secast 
 ).  If allows you to set thresholds for the 
number of attempts, and specify the period in which they occur.  The Free 
edition of SecAst is a drop-in replacement for fail2ban (but with a lot more

Hi. I would like to protect my system from failed attempts. I would like to ask 
if there is a way to do a blacklist for certain amount of time consecutive 
attempts from the same IP. For example if we have an IP that gets a wrong 
passwd an it had tried more than 3 times the last 5 minutes, blacklist it for 
an hour. I have tried to implement it through fail2ban, but it doe snot seem to 
work for my asterisk implementation.

Is there any other way?

Re: [asterisk-users] Detecting DoS attacks via SIP

[Telium Technical Support]

If this is a home system, try the free edition of SecAst (www.telium.ca/?secast 
<http://www.telium.ca/?secast> ).  It uses the AMI for detecting simple failed 
events , but can do more than fail2ban.  More importantly it can block at the 
network edge by talking to you firewall (don’t let the script kiddies onto you 
LAN).

 

If decide to try geofencing using just IP rules than you will really slow your 
system (as the number of rules and exceptions is massive in order to be 
useful).  There are some open source IP to location services (SaaS) which are 
free if it’s not for commercial use.

I appreciate the discussion on the question I asked.

I currently listen for failed registration attempts via AMI and automatically 
block the offending IP address at the firewall.  I was hoping to find another 
AMI event that would be the magic bullet I need, but it doesn't sound like 
that's going to happen.

I understand that fail2ban is probably not what I want and probably wouldn't 
detect the attacks I'm seeing.

It turns out that not all of the attacks are from the "friendly scanner," but 
enough of them are that it's a good start.

So, I really like the idea of the IP geo location firewall rules coupled with 
the "friendly scanner" filter, as provided by a few of you guys.  It was 
mentioned that this is a broad hammer, but I'm kinda looking for a broad 
hammer! ;^)

Looks like I need to do some research, but I think I have what I need.

Thanks again,

Mike Diehl.

So, how are other people handling this?  Is there an AMI event I want watch

Any ideas?

Hello!

I'm still trying to get a working t.38 configuration w/ pjsip.

I'm now able to send t.38 faxes to my own extension:


hylafax -> t38modem -> extension -> extension -> t38modem -> hylafax.


The fax is sent by t38modem. The receiving part of t38modem accepts the
call, sends ReInvite for t.38 and things are working as expected.



Now, let's do the nearly same thing, but use an ISP:

hylafax -> t38modem -> extension -> trunk -> ISP -> trunk -> extension ->
t39modem(2) -> hylafax


Same procedure: the receiving t38modem(2) sends ReInvite for t.38 - but this
time, the extension / asterisk just ignores it. After the 5. retry to switch
to T.38, asterisk tells:

res_pjsip_t38.c:207 t38_automatic_reject: Automatically rejecting T.38
request on channel 'PJSIP/91-0007'

=> Why does asterisk reject the switch / ReInvite to T.38 this time? It
never even tried to send it to the ISP!


Thanks for any hint!

Michael

Re: [asterisk-users] iaxModem pickup problem

[Telium Technical Support]

The file astdb.sqlite is a SQLite 3 file (all tables and indices rolled into
one file).  While Asterisk is running the astdb file is always open for r/w.
FreePBX regularly updates rows ("keys") in this database, so writes are
often in progress.

In the event of a power failure the file will not be properly closed, or
worse be left in an invalid state.  Once Asterisk starts it is may refuse to
read some astdb rows, or potentially the whole file.

Asterisk natively does not need the astdb file but FreePBX makes extensive
use of it.  In particular, FreePBX dialplans check device/user information
in the astdb for call handling.  So a missing/corrupt user/device will cause
the dialplan to fail.  (That's why I suggested to you watch the dialplan
from the Asterisk CLI when a fax comes in).

This design (FreePBX) makes Asterisk much more fragile than it has to be.
It's a good idea to keep a backup astdb on the PBX in case of corruption.

No, I did not try to restore from backups; and yes I have daily backups to
recover from if that is necessary.  However, I have since corrected the
damaged rows in astdb.sqlite and the fax service is now working again.

If someone could explain what likely happens to damage astdb.sqlite when the
system is suddenly powered off I would appreciate it.

It depends a bit on your version of FreePBX, but here's a link to show you
how:

http://telium.ca/pages/forums/viewtopic.php?f=7&t=19

Hopefully option 1 works for you (quick and easy).  If not, you'll have to
try option 2.  Ignore option 3 since that's only for users of High
Availability for Asterisk (HAAst).

(I assume that if you had a full backup you would have already tried to
restore it)

Our company started building Asterisk based PBX in 2002 and Multi Tenant PBX in 
2005 - we do this as our core business and are still finding areas for 
improvement :). As your experience with VoIP is minimal I would side with your

Hi,

I have a voicemail broadcast AGI that has been running fine for years - it
collects extensions and then EXECs the Voicemail app, like this:

EXEC Voicemail \"%s\"

(%s is the extension list like AAA&BBB&CCC etc)

This works fine, but after leaving the message and pressing "#", I just get
"Thank you" and a hangup.  I would like to have the option to review,
re-record, or cancel.  It isn't clear how to enable this option via EXEC.  I
tried:

EXEC Voicemail \"%s,review=yes\"

but there is no effect at all.

Any clues?

Thanks,

Re: [asterisk-users] Having problem getting Asterisk to work on CentOS 7

[Telium Technical Support]

Dan - you probably installed the init script (look in /etc/init.d for an
'asterisk' file).  Asterisk includes the older init style scripts which are
*compatible* with systemd but you don't have as much control compared to
creating an Asterisk systemd file.  (SystemD service files replace InitD
scripts).  So that might be part of the solution, but first.

 

If disabling Selinux allows Asterisk to run as you expect then you can
create an selinux policy exception for Asterisk - BUT, ignore that for now.
Just keep SElinux disabled (edit /etc/sysconfig/selinux and set to disabled)
and come back to that later.

 

So in preparation to diagnose further:

1.  Disable asterisk service (systemctl disable asterisk)

2.  Disable selinux (as described above)

3.  Reboot.

 

Next, try to start asterisk with 'systemctl start asterisk'.  Does it work
as expected?  If no, what user have you logged in with?

If not root, su to root and try again.  Did it asterisk service start
properly?

If yes, you should create a systemd service file and use the 'user=root'
parameter (and remove the initd service script).

Does Asterisk start properly now every time?  If yes re-enable to your
systemd Asterisk service to start with the system.

 

I don't see any attachment (probably stripped by the list manager) but that
shouldn't matter - if your Asterisk service is not running as root that
would explain a range of strange behaviours.

Subject: Re: [asterisk-users] Having problem getting Asterisk to work on
CentOS 7

 

Thanks Jason.

 

I will try to explain what I'm seeing for this issue.

 

I did a fresh install of CentOS 7 Minimal into a VM with VMWare Workstation.
Followed the Asterisk from Source instructions using pjproject 2.6 and
asterisk 13.14.0 for the configure, install, .   At the end of the asterisk
portion, I ran the make config which I understand installs the
Initialization scripts.

 

After this, when I restart my CentOS 7 Minimal, I was seeing the
safe_asterisk process, but asterisk would not start.  I could run it from
the command line and it would run.

 

It was suggested that it's an selinux problem.  They had me try 'setenforce
0'.  After this, asterisk process starts running.

As I understand it, there was mention of using systemd instead of using
safe_asterisk.

Other e-mails indicated I should look at the audit.log, so I included that
information.  This audit.log mentioned astdb.sqlite3, so I wasn't sure if
that's the problem.

 

I also just tried a restart and ran 'systemctl start asterisk'.  This did
not start the asterisk process.

 

Through the various recommendations, I've become confused on what the
correct path would be.  I have had zero problems with Debian and Asterisk
for many years.  Making the change to CentOS.  Followed the instructions
from asterisk.org, but for some reason I hit a problem with this on my
CentOS VM.  

 
<https://wiki.asterisk.org/wiki/display/AST/Installing+Asterisk+From+Source>
https://wiki.asterisk.org/wiki/display/AST/Installing+Asterisk+From+Source

 

Simply looking for guidance on what the correct approach to solve this
problem is.

 

Have a great day!

The history of the question is lost (in the mail thread) so I'll jump in
based on what I could see in my recent mail and the subject line:

-The ASTDB should have no impact on Asterisk service start (which I
assume is the problem given the subject line)

-If you disabled SElinux then that's not the problem in starting
asterisk

 

>From another posting it appears that you can start Asterisk from the binary,
and from safe_asterisk.  If that's correct, then are you able to start/stop
Asterisk from the service file?  With CentOS7 that would be:

 

systemctl start asterisk

 

Is your asterisk service file present?  (You can create one easily based on
samples on the internet).  If you have an asterisk service file but startup
fails post the relevant portion of your syslog (journalctl).

 

If your question has changed (you mentioned 'the first problem') then ignore

Re: [asterisk-users] fail2ban Asterisk 13.13.1

[Telium Technical Support]

If this is a small site, I recommend you download the free version of SecAst
(www.telium.ca  ) and replace fail2ban.  SecAst does
NOT use the log file, or regexes, to match etc.instead it talks to Asterisk
through the AMI to extract security information.  Messing with regexes is a
losing battle, and the lag in reading logs can allow an attacker 100+
registration attempts before fail2ban even does anything (assuming the IP is
exposed in the Asterisk log).

 

If this is a large install then post in the commercial list for more
information.

It's possible that you need to increase the value of 'findtime' to
something greater than 300 secs. You also may want to set "timestamp = yes"
in asterisk.conf so each line in the CLI will be time stamped. Time stamping
it will be the definitive determination on whether or not the 'findtime' is
the culprit.

[asterisk-users] Replacing PBX during a call in progress

[Telium Technical Support]

This was asked many years ago but I thought I would check to see if things
have changed.  Is it possible to take over a call in progress - using a
replacement Asterisk server?  

 

In other words, if 2 user agents are connected through an Asterisk PBX, and
I tracked the call ID, IP of each UA (and anything else needed), could I
remove the PBX and put a new one in its place (at the same IP address) and
resume the call?  Somehow keeping the call up on the UA's and telling
Asterisk to just resume a call given specified parameters (so the UA's
wouldn't notice the change)?

Re: [asterisk-users] Issue command to force SIP client to re-register

[Telium Technical Support]

Thanks - I actually found the SIP notify command before, but the options
seem to force checking for new config (in which case reboot), or cold/warm
restart.

 

I was hoping to just force a re-register, not reboot.  (Which in this
particular case is a long interval which I cannot change, so need to force
re-register on demand).

[asterisk-users] Issue command to force SIP client to re-register

[Telium Technical Support]

Is there a way to force a SIP client to re-register using a SIP command (or
an AMI command)?

 

If not, is there some other standard way to do so - or would I have to
post/get to a web GUI of the phone (unique to each model) to force a reset,
etc.

[asterisk-users] AMI version in Asterisk 14

[Telium Technical Support]

I noticed that Asterisk 14 has changed the output format for some commands
(eg: "Output: ").  However, the AMI reports version 2.8.0 which is the same
as Asterisk 13

 

Is that considered a bug?  Since the AMI output format has changed,
shouldn't the AMI version be incremented?  (Makes is hard for developers to
maintain compatability)

Re: [asterisk-users] RS485 Audio device

Forget RS485 at that distance (your throughput will be too low).  I would 
suggest you pull a fiber and just create an LAN connection on the end.

Hi All,

 

The reason for the question was simply that the customer desired some solution

called an "AOR" or Area of refuge - I think it was. Basically a call button, 
microphone and speaker to hear back

with the kicker being "a long distance" the solution has to run.  RS485 is like 
4000 feet.

 

There are solutions our there apparently that are not built on asterisk - so I 
was just trying to find

a solution that potentially worked with asterisk. 

 

Thanks!

Re: [asterisk-users] RS485 Audio device

[Telium Technical Support]

This one caught my interest too...more out of curiosity!  Keep in mind that
RS485 max speed drops to 100kbps after a relatively short distance.  And,
100kbps is RAW speed.  If you encapsulated your audio stream in that you'd
lose another 10%.

So why are you doing this?  If you are running a 100m cable (4 wire +
shield) why not just pull at cat5/6 cable instead?  Or just send analog
audio over 2 of the wires with the shield to keep out hum.   If there is a
need to use rs485 you could stream your audio over that connection - but I'm
curious why first.

We did some work for broadcast (radio station) doing AoIP and converting
some analog feeds but this seems unusual.

Ok, I'll bite.  How does one do audio over RS485?

I've never worked with RS485, but from some brief googling it looks
like it's a fancy version of RS232.  I'm not sure where you'd get
(analog) audio from on RS232.

Re: [asterisk-users] IAX UNREACHABLE : Ignoring bindport/bindaddr on reload

[Telium Technical Support]

This shows that asterisk's IAX is already bound to all adapters - so that's 
good.  Symptomatically does your IAX stop working?  Or do you just see a 
warning?

[asterisk-users] How does Ast use IP vs FQDN for SIP header fields

[Telium Technical Support]

We are working with an ISP that needs Asterisk to place a FQDN name in the
SIP 'FROM' and 'INVITE' fields - where Asterisk is currently using an IP
address.  A SIP trace shows the following from my Asterisk box:

 

INVITE sip:62351155@1.1.1.1 SIP/2.0

Via: SIP/2.0/UDP 2.2.2.2:5060;branch=z9hG4bK49f1d30e

From: "MYNAM" ;tag=as3d9596b0

 

We tried adding hosts file entries mapping these IP's to hostname's but
Asterisk didn't use them.  Can someone suggest how to do this?

Re: [asterisk-users] asterisk admin interface

[Telium Technical Support]

You don't mention a configuration generator (like Elastix/FreePBX) so I'll
assume you are using a plain old vanilla Asterisk installation.  In which
case all user/endpoint information is kept in config (ini) files, and no
user/endpoint manipulation is done through the CLI or AMI.

In this case a very simple solution is to modify the Asterisk config files
to add/remove users, then tell Asterisk to reload from the CLI/AMI.  And
that's it!

Re: [asterisk-users] AMI: check if the user has a Mailbox

[Telium Technical Support]

I don't think the directory check method is reliable; a user can have a
mailbox but if no messages have been left then the directory structure may
not exist.  Through the AMI you can show peer/user information and I believe
it shows you the mailbox associated with user/peer.

I don't think you are going to be able to get that information using the
AMI. You should be able to figure it out though by looking at the voicemail
directory structure in /var/spool/asterisk/voicemail// or
in your database if you're using real time. It's probably just as easy to
write a script that will look for the proper directory as it is to write a

I found the AMI-Command MailboxStatus, but it does not return what I need,

Could someone suggest me a way to get this information?

Re: [asterisk-users] Failed to authenticate device 100

[Telium Technical Support]

The details of the source IP are available in the asterisk security log (if you 
have that enabled) – but that particular attack hides its address from the 
messages file.

 

It’s essential that you secure your PBX; there are options ranging from free to 
commercial.  Have a look at:

 

http://www.voip-info.org/wiki/view/Asterisk+security

 

It’s easy to get a $20,000 phone bill, so take securing your PBX seriously.

Re: [asterisk-users] Which router/firewall would you use for a virtual-PBX Asterisk installation?

[Telium Technical Support]

If you are focused on routing, we've used 4 Cisco SG300-28p in router mode -
economical way to handle vlans etc for ~100 POE phone sets,  (with GB
interconnects).  At the edge Cisco ASA-55xx work well, and we've done a few
deployments with Mikrotik routers that are quite inexpensive and performed
impresively for their cost.

>From a security standpoint, consider what happened last summer when hackers
found an exploit in the FreePBX web interface.  They rewrote the PBX
dialplan, disabled CDR's, and made unlimited calls to premium rate numbers.
This was a real wakeup call for FreePBX users who though Fail2Ban was a
security system, or CDR's could be used to catch compromised accounts.
Digium warns everyone that fail2ban is not a security system:
http://forums.asterisk.org/viewtopic.php?p=159984

If you don't want a security system on your PBX, see if your ITSP will limit
your account to $X/day, restrict routes, etc.  

There are also some great Astricon videos online where they invite speakers
to talk about security.  You'll see that fail2ban + A2Billing doesn't keep
out anyone except the script kiddies.

Oh, don't worry about us going cheap on security. We use A2Billing 
(along with some Fail2Ban configuration for bad logins) to limit the 
number and cost of calls that can go out through a compromised SIP 
account, so that when, not *if*,  a customer's SIP account gets 
compromised, the attacker gets cut off at the knees before they can even 
get out the door. We've even added bogus connection charges on 
international calls that get removed before we bill our customers, to 
speed up the process and reduce our losses even further. Our customers 
are even happy that these billing limits are in place.

No, this is all about playing nice with our load balancing software and 
protecting databases and backend servers that have no business being 
available to the public. But mostly it's about the load balancer 
(IPTables on said servers can take care of "visible to the public). I 
just want to make sure that the router we use will play nice with 
Asterisk, since we've already seen network hardware that looks good on 
paper, but fails miserably in practice. In fact, we see it so often with 
individual customers' crap routers causing voice quality issues, that by 
default we don't trust simple math.

So here I am, asking everyone what router they use, and whether you're 
happy with the results when there's 100 simultaneous SIP calls in 
progress. I want to know what happens when the rubber hits the road.

Re: [asterisk-users] Which router/firewall would you use for a virtual-PBX Asterisk installation?

[Telium Technical Support]

Well router and firewall are very different...it depends on what you are
trying to accomplish.

If you are trying to secure an Asterisk-based call center, get a real
security product.  Look here for details:
http://www.voip-info.org/wiki/view/Asterisk+security

This covers firewall, Asterisk lock-down, and Asterisk specific security.
The average break-in/fraud cost is $25,000 per day.  (watch the Astricon
videos for more details).  So going cheap on security isn't a smart move for
a commercial installation.

If you just want a router/switch, figure out the simultaneous call capacity
x codec demands in bps, and there is your backplane switching speed
requirements.  Even with 100 simultaneous calls at g711, a lower end Cisco
(3xx) router/switch will have no problem.

security hardened and exposed to the internet for them to connect to 
remotely with SIP and IAX. It's certainly not the sort of affair where 
we're running it as a PBX just within the building. As a result, we see 
network traffic coming through eth0 between 512 Kbps and about 3.0 Mbps, 
depending on the time of day.

We haven't so far been using a hardware firewall/router on our server 
network, but it's becoming increasingly clear that we need to. We have 
enough experience to know that Asterisk is pretty sensitive when it 
comes to network hardware in our situation - we've had to replace one 
otherwise perfectly good 100 Mbps network switch because it simply 
wasn't able to keep up with the amount of streaming audio we put through 
it, and it badly affected voice quality. We have other traffic flowing 
through our server network too, including a significant amount of e-mail 
and web traffic, although that's not quite as sensitive to the quality 
of our network hardware.

If you've got these large requirements for Asterisk, I'd love to hear 
what you use for a router, and whether that router has met your needs. 
It would also be nice to hear about what kinds of routers to avoid that 
you may have tried in the past and found lacking.

Re: [asterisk-users] Asterisk HA with heartbeat and systemd

[Telium Technical Support]

If you’re still in the planning stage, there’s a lot more to think about.  Your 
Asterisk failure detection will be very simplistic (is the process dead).  
Synchronization of data – without risking synchronization of corrupt data to a 
peer.  Prevent a deteriorating/failing peer corruption from corrupted the other 
peer (i.e. now shared resources).  Awareness of upstream (e.g.: route/network) 
failures making the peer unavailable – and how to detect that.  Etc. etc.

 

Here’s a good checklist of things to consider in your design:

If you are building a small/home office HA then the free version of commercial 
tools may be the way to go.  If have a $0 budget but for a larger installation, 
use the design guide above to help figure out which compromises to make.  
(Heartbeat / Linux HA is better than nothing).
