<br>
I've been aware of Kamailio, and on this list, for several years, but so far I <br>
have not implemented Kamailio for any purpose.<br>
<br>
I wonder if it could be a suitable tool for the following scenario.<br>
<br>
I currently use Asterisk to register as a client, with username and password, <br>
to other SIP PBXs in order to receive calls. As far as the other PBX is <br>
concerned, Asterisk looks like a SIP telephone on a particular extension.<br>
<br>
However, Asterisk's SIP client capabilities are limited to handling phone <br>
calls only, and it specifically cannot receive presence information about the <br>
state of other extensions from the remote PBX.<br>
<br>
So, could Kamailio be used in the path between Asterisk and the remote PBX so <br>
that the registration on the PBX comes from Kamailio (with any incoming calls <br>
being passed to Asterisk), but with Kamailio also receiving presence <br>
information from the remote PBX and making this available to some script or <br>
application (which I would expect to have to write)?<br>
<br>
The main point is that I don't want to have two things registering to the <br>
remote PBX, one for calls and one for presence, so I'm looking for a way to <br>
register with something which understands presence, and can also pass calls on <br>
to Asterisk.<br>
<br>
Can anyone suggest whether Kamailio could do this, and if so, point me at some <br>
resources to help me get started; or alternatively suggest ideas on some other <br>
tool which might be more appropriate than Kamailio?<br>
<br>
<br>
Thanks for any ideas,<br>
<br>
<br>
Antony.<br>
