Oh, certainly - there's a whole load I didn't mention in my description :)

I'm using Asterisk to place and receive calls through the external PBX systems 
- it's registered as a SIP client, and essentially behaves as a soft phone as 
far as the external PBXs are concerned.

Alongside placing and receiving calls, though, I need the presence and 
voicemail information, therefore I'm looking for a reasonable way to combine 
that with Asterisk which handles the calls themselves perfectly fine.

And, before anyone suggests it, no, I can't simply replace Asterisk with an 
actual softphone application, because there's a very complicated dialplan 
behind all this, including directing calls up SIP trunks quite separately from 
the SIP registrations to the PBXs.


Thanks,


Antony.

Hm, thanks for the clarification, this confirms what I suspected.

Can anyone suggest an alternative application I could sensibly use alongside
Asterisk in a production environment to achieve this (I'm specifically looking
for a way to maintain presence information for a Busy Lamp Field, and to get
notifications about Voicemail events).

something which can subscribe to a few tens of SIP accounts (across several
servers) and get the event notifications for those accounts, over a period of
days and weeks, and pass them to my display application in almost any
reasonable form).


Any ideas out there?



It sounds to me like you just need a reasonable SIP softphone that can 
register with multiple SIP accounts (they all do) and show presence for 
the extension registered (I think most want you to pay for this feature 
versus the freebie client).


Why run asterisk?

Am I missing something?

Hm, thanks for the clarification, this confirms what I suspected.

Can anyone suggest an alternative application I could sensibly use alongside 
Asterisk in a production environment to achieve this (I'm specifically looking 
for a way to maintain presence information for a Busy Lamp Field, and to get 
notifications about Voicemail events).

I'm aware of both SIPp https://github.com/SIPp/sipp and SipSak 
https://github.com/nils-ohlmeier/sipsak, however these are (to me at least) 
testing scenario tools designed for "short term" use to place and receive 
calls, rather than maintaining long-term subscriptions to SIP accounts, 
waiting for notifications of events, so I'm somewhat wary about considering 
them for use in a production environment (by which I mean I'm looking for 
something which can subscribe to a few tens of SIP accounts (across several 
servers) and get the event notifications for those accounts, over a period of 
days and weeks, and pass them to my display application in almost any 
reasonable form).


Any ideas out there?


Thanks,


Antony.

There is no functionality present to have Asterisk SUBSCRIBE to upstream
servers, receive updates, and locally use them.

[asterisk-users] Asterisk registrations - state?

2020-12-08 Thread Antony Stone 
Hi.

I'm using Asterisk 16.2.1 with some registrations (ie: my Asterisk server is 
registering to other PBXs as though it were a telephone).

Is there any way I can get presence / state information from those PBXs in the 
same way that a registered telephone can?

In other words, can I send a Subscribe request to the PBX so that I get Notify 
announcements about other extensions and whether they're idle / busy / ringing 
/ etc., the same as BLF indicators on a SIP phone can do?

I've looked at 
https://wiki.asterisk.org/wiki/display/AST/Querying+and+Manipulating+State but 
this appears to be only for the state of clients registered to my Asterisk 
instance, not for the state of clients registered to the same remote PBX as 
Asterisk itself is registering to.


Thanks,


Antony.
