IMHO, kids are the ones likely to use the more advanced features... ie,
conferences, and anything else likely to tie up multiple in/outbound
calls at the same time...

You might consider permitting them to throw their own mp3's onto the
server for their personal MoH 

 I thought that having some common area phones share a single extension 
 (wired into a single ATA FXS port) might ease the transition, but I'm 
 also afraid it might be confusing (you can just pick up from these 
 extensions, but you have to transfer or park to/from these extensions. 
 Huh?).

Program one of the speed-dial keys to transfer the call to a meetme with
MoH. Then tell them that to put the call on hold, just press this
button. Then label the next closest speed dial as Pickup which simply
dials the meetme room. Of course, if you have multiple 'lines' you might
need some 'custom' dialplan magic to ensure a hold will always add you
to a new empty meetme, while an unhold will take you to the oldest
meetme which hasn't been 'un-holded' yet :)

Otherwise, you might as well teach them about parking Still, a
button for Hold which does a #700, and then they just walk to any
other phone and dial 701 (or whatever) should get you most of the way
there. Just remember to set a short-ish parking timeout which will
call-back the phone .

 The huge selling point, which I'm hoping will overcome any initial 
 resistance, is the idea that one person will no longer tie up the whole 
 phone system for the house when they make/take a call.  And deploying 
 one of my free DIDs to give my 16-year-old his own phone number that 
 rings only in his bedroom is the real ace up my sleeve!

Yep, neat + his own direct VM etc...

 Sure, Asterisk will come with a lot of other neat features, but frankly 
 most of them have more geek appeal (though I have high hopes for my 
 favorite feature -- announced caller id over the stereo/tivo while we're 
 making dinner -- to revolutionize the way we deal with (or at least who 
 answers ;-) ) phone calls at that hour), and in some cases I think may 
 face similar that's not the way it's supposed to work objections.  For 
 example, while they will acknowledge that voicemail is cool, I suspect 
 they'll miss the simplicity of walking into the kitchen, seeing if the 
 answering machine is blinking, and just pressing the button.

Use phones that have a VM indicator then program a speed dial for
your VM extension.

 I'm excited AND anxious about starting a real beta test with them! 
 Maybe that's why I'm already 3 weeks behind my original schedule. ;-)

Well, looks like you are close, I think the biggest one to test
thoroughly is the echo. That is probably the hardest one to ask
people to live with...

Adam

Re: [Asterisk-Users] sharing a line w/multiple extensions

2005-12-15 Thread Rich Adamson
  I'd like to configure Asterisk so an incoming call from one POTS line 
  is shared amongst multiple extensions - both SIP and analog.  i.e.  
  If one SIP phone answers the call, another SIP or analog extension 
  phone can pick up and join the conversation.  How do I configure 
  this?  Is it all in extensions.conf?
 
  Asterisk is not a key system. It does not behave this way.
 
  What do you mean by 'another SIP phone can pick up (...) the 
  conversation'? Exactly what would the SIP phone user do to accomplish 
  that?
 
 Think residential installation where someone picks up the phone in one 
 room but someone in another room wants to join the conversation.  
 Ideally, I'd like to have Line 1 on every phone (SIP or analog) behave 
 this way.  Another poster pointed out a good potential approach using 
 meetme.  When an incoming call comes in, it dials all SIP + analog 
 phones.  When someone picks up (don't know how I can detect this), it 
 could transfer both parties to a meetme room.  When additional 
 extensions pickup, they go to the meetme room.  When everyone hangs up, 
 the call ends.  Can this be done?

There might be a way for you to address your objective depending upon
exactly what you're trying to do.

The previous responses to your question _assume_ that each room in
your case has a pbx extension (regardless of whether its a sip or analog
phone). If their assumption is correct, then the responses are correct.

However, if you want to use your existing analog phones and you group
them together, several analog phones can share a single extension
and those phones in the group can pick up and join the conversation
whenever they want. Think in terms of using something like a Sipura
sip adapter (or the equivalent from other vendors), and connecting all
analog phones within your defined group to the rj11 analog jack of
the adapter.

For example, I have four analog pstn lines and multiple iax connections to
various itsp's and clients. One of the analog pstn lines is a house line
and connects directly to * via a TDM04b card. When an incoming call occurs
on that line, it rings multiple sip phone/adapters. One of those happens
to be a Sipura spa3000 that has most of the analog house phones attached.
Anyone one of those phones can answer the call, others can join in, etc.

The approach can work if you can define specific groups of interest
such as kids vs adults, sales vs support, home vs business, etc.
Combine that approach with carefull selection of analog phones (those
with some form of line in use LED), and you end up with an approach
that sort of looks like a poor-man's key system behind a pbx. Pay attention
to the features within the sip adapter (eg, Sipura) and you're likely to
find additional options that might address your needs.

All depends upon exactly what it is that you're trying to engineer.

One system I found that works well in a home environment is using a
two-line, multi-handset cordless phone system. Run 2 analog ports to the
base station, and this handles most home needs. Two users can make or
receive calls, join existing calls, etc rather easily. The dial plan is
set so that either line makes outgoing calls over a VoIP service, line
2, or whatever, so that the main incoming line is always available to
receive calls. 

The home office has a Polycom 601 with it's own lines and dial plan
logic, plus the fact that the polycom user is much more likely to
know how to answer, transfer, park, etc.

Wife proofing a * system is non-trivial and takes careful planning.

  Probably, but it would take some very creative dialplan programming 
  and an external application to transfer the parties into a meetme 
  room. You will not get 'pickup' behavior on the SIP phones regardless, 
  they will have to press a speed dial button which would attempt to 
  join the meetme.
 
  In other words: you can get there, but it will _not_ behave like a key 
  system, and people will expect it to, so they will be frustrated when 
  it doesn't. We've been down this road many times before, and many 
  Asterisk installations have been taken out because the installers 
  thought they could achieve key system behavior (or retrain the users) 
  but failed. If you want to try, feel free... I'm only telling you what 
  has happened before :-)

 Thanks.  That's very helpful because being new to Asterisk, I don't know 
 the history of what people have attempted to use Asterisk for.  It's 
 unfortunate that there's no way to do it because it sounds like others 
 are looking for this same functionality.  I wonder what it would take to 
 implement this in Asterisk natively.  Does Digium take feature 
 requests?  Certainly, this would have appeal for residential systems.

Just a couple of comments on the subject of key systems verses pbx's

The traditional pbx (from years ago) implemented exactly what Kevin
mentioned above. Just about every company that deployed a pbx back then 
also had several key systems attached to their pbx. The key systems were
typically limited to executives and their assistants (secretaries
back then) primarily due to the additional cost of the older key systems.

The traditional pbx vendors (back then) would always use the same words
that Kevin used, emphasizing the differences between key systems and
pbx's. However, many of the pbx manufacturers finally realized they
were loosing revenue due to those limitations, and began implementing
key-system-type functions in their pbx's. They were not trying to address
the key system market, but rather make their pbx products more valuable
from a user's perspective. Those that are influencing or controlling the 
direction of asterisk haven't learned that lesson as yet, partially because 
of the lack of functionality in the sip phones themselves and partially 
because asterisk is being developed through the open source community 
(limited development resources and no published long term plan).

Those individuals that have worked towards developing the sip rfc standards
have recognized some of the key system vs pbx needs, and have added to
the sip standards. However, it takes a while for the sip phone manufacturers
(and voip pbx manufacturers) to implement those standards, and in some 
cases, the manufacturers purposefully leave out certain functions in their 
sip products to protect their investments in proprietary products.

It certainly is not difficult to visualize how voip switching products
(such as asterisk or any of the commercial products) could be oriented
towards being a switch and address the needs of key systems, pbx's,
and central office switching in the same basic product. All of the same 
functions are required in each case. Asterisk will get there, it will just
take a little longer since there isn't any published long term plan to
influence the short term development. (No offense intended to any asterisk
individual or group; just the nature of most open source development.)

I can also assure you that several large companies (most of those company
names likely wouldn't be recognized by many of the readers here) are 
watching the asterisk development closely, and likely are in fear of various 
open source products negatively impacting their core business. They will
adjust their product development (and plans) in an effort to remain one
(or more) steps ahead from a marketing  sales perspective.

Thanks for the history on PBX and key systems.  History has a way of 
repeating itself.  I think Asterisk will have to implement features of a 
key system in the near future.  Just judging from the reaction from 
friends and family who are fascinated by my Asterisk installation, there 
is huge demand for this kind of system.  Digium is just losing out on sales.


Is there an open source key system?  What other alternative systems are

Rich, Kevin

I just stubbled into one of these projects. I am making it work for
the client but constantly running into walls. Client is very cool
about the work and loved the history of the Key
System from Rich.

Current issues and solutions:

Busy boxes = SNOM 360s with Sidecars
Static Parking(orbit or 60) = Seperate MeetMe rooms (MOH if single user)
Paging = Extra SIP line on the phones set to auto answer, ugly chanisavial check
No Voicemail = a, bounce to Oper
Queues = Hard Code procedural so that I can hint the phones right.
answer at any phone = button hack for the blinking button.

Maybe I should submit this job to Digium for the contest :-)

Re: [Asterisk-Users] sharing a line w/multiple extensions

2005-12-15 Thread Robert La Ferla
Is there a way for another extension to join a call in progress?  i.e.  
If I can't share the line with all extensions, it would be nice to have 
a single button (dial sequence) that allows any extension to join the 
call.  How can this be configured?

Probably through some creative use of meetme.  But IMO once you start
using hacks like that, you should probably either look at alternatives
or adapt to a different way of doing things.  It's also possible that
there is a solution that would work well for you, but as always it
depends on the details.  You might post your exact setup, hardware,
number of phones, what type of environment they are used in, etc.. 
For example as someone else mentioned in a home environment you can do
something similiar to what  you want using the sipura SPA-3000.  It's
possible, depending on the details, that a similar solution might
exist in your case.  I kind of doubt it, but it can't hurt to try.

Re: [Asterisk-Users] sharing a line w/multiple extensions

2005-12-15 Thread Jean-Michel Hiver


I'm particularly worried about acceptance of this shared line (or 
lack thereof) aspect of the system.  My wife will get the idea of 
extensions, transfers, parking, etc. because she uses a PBX at work, 
though I worry that the habits of how the phone is supposed to work 
at home may die hard with her.  And the kids are a whole 'nuther story.


If you're using VoIP, then you don't have to worry about the shared 
line issue. Outgoing calls will work all the time (well, assuming your 
VoIP provider works which is a big IF I guess). You can keep your 
landline for 911 calls.



The huge selling point, which I'm hoping will overcome any initial 
resistance, is the idea that one person will no longer tie up the 
whole phone system for the house when they make/take a call.  And 
deploying one of my free DIDs to give my 16-year-old his own phone 
number that rings only in his bedroom is the real ace up my sleeve!


Sure thing :)

Sure, Asterisk will come with a lot of other neat features, but 
frankly most of them have more geek appeal (though I have high hopes 
for my favorite feature -- announced caller id over the stereo/tivo 
while we're making dinner -- to revolutionize the way we deal with (or 
at least who answers ;-) ) phone calls at that hour), and in some 
cases I think may face similar that's not the way it's supposed to 
work objections.  For example, while they will acknowledge that 
voicemail is cool, I suspect they'll miss the simplicity of walking 
into the kitchen, seeing if the answering machine is blinking, and 
just pressing the button.


You could use the voicemail to email feature. It's as nice as it gets. 
Who doesn't check their emails like 20 times a day nowadays? :)


Cheers,
Jean-Michel.

Let me revise this a little:

I'd like to configure Asterisk so an incoming call from one POTS line is 
shared amongst multiple extensions - both SIP and analog.  i.e.  If one 
SIP phone answers the call, another SIP or analog extension phone can 
pick up and join the conversation.  How do I configure this?  Is it all 
in extensions.conf?

I have that but once one extension picks up, others can't join in.  
Well, at least when I tried it with mixed SIP and Zap, it didn't work.  
Maybe all SIP does but I need it to work for all phones SIP and analog 
(via Zap).

Have you try first blind transfer to a meetme meeting room. Then multiple

Asterisk is not a key system. It does not behave this way.

What do you mean by 'another SIP phone can pick up (...) the 
conversation'? Exactly what would the SIP phone user do to accomplish that?

Think residential installation where someone picks up the phone in one 
room but someone in another room wants to join the conversation.  
Ideally, I'd like to have Line 1 on every phone (SIP or analog) behave 
this way.  Another poster pointed out a good potential approach using 
meetme.  When an incoming call comes in, it dials all SIP + analog 
phones.  When someone picks up (don't know how I can detect this), it 
could transfer both parties to a meetme room.  When additional 
extensions pickup, they go to the meetme room.  When everyone hangs up, 
the call ends.  Can this be done?

Probably, but it would take some very creative dialplan programming and 
an external application to transfer the parties into a meetme room. You 
will not get 'pickup' behavior on the SIP phones regardless, they will 
have to press a speed dial button which would attempt to join the meetme.


In other words: you can get there, but it will _not_ behave like a key 
system, and people will expect it to, so they will be frustrated when it 
doesn't. We've been down this road many times before, and many Asterisk 
installations have been taken out because the installers thought they 
could achieve key system behavior (or retrain the users) but failed. If 
you want to try, feel free... I'm only telling you what has happened 
before :-)

the history of what people have attempted to use Asterisk for.  It's 
unfortunate that there's no way to do it because it sounds like others

Re: [Asterisk-Users] sharing a line w/multiple extensions

2005-12-14 Thread Adrian Carter

Just as an aside... some Sip ATA's come with both Hotline  Warmline
settings with configurable timeouts. Do any software ones offer similar
functionality? Regardless, it could achieve almost that outcome using
Wamline (to auto-enter the meetme-finding-extension that interfaces with
external program to find actual meetme for the conversation to join and
then transfer the call into) and suitably short timeouts. It would have
the corresponding effect of allowing people to 'optionally' join the
call by just picking up and waiting 5 seconds.. or alternatively,
dialling a differnet number and launching a seperate call.

I could picture it working 'almost' like the author wants through the
use of cordless phones/hardphones plugged into an ATA that supports
wamline configured with the below said 'messy in the middle
dealing-with-meetme' program

Our list of feature requests is a mile long, but yes, we take them. 
Money makes them happen sooner, sometimes :-)


Implementation of this in a proper way will require true 'shared line' 
functionality in Asterisk, which is a non-trivial thing to add. On top 
of that, there is no money in 'residential' Asterisk systems, because 
cheap key systems can do the job for less than the SIP phones alone 
would cost, let alone a box to run Asterisk on and TDM interface 
hardware. It has a high 'geek factor', but regular people would just get 
frustrated by it (in my opinion, of course). That means the people who 
really desperately want this behavior also have no resources to make it 
happen... so we are at a stand-still.
