Hello to the list!<br><br>I'm implementing a OpenSips registrar/sbc configuration and I have a problem with presence.<br><br>In my configuration I have a OpenSips 1.6.4 as a SBC. The phones must register only in OpenSips. After the SBC, there is a pool of Asterisk. I use dynamic routing module to forward the calls to pool, using my own rules (classify by client, a prefix in the username).<br>
<br>My main problem is that Asterisk must know the state of the phones and the number of calls in each phone. the pool of Asterisk must know the state of each device and the number of concurrent calls because queue strategies.<br>
<br>I had read a lot about presence, xmpp, module pua_xmpp, asterisk pubsub and others but is a bit difficult to understand for me.<br><br>The phones are mainly Cisco SPA phones, and I must support BLF in those phones too.<br>
<br>my questions are:<br><br>Somebody knows if using XMPP I can share presence info between OpenSips and Asterisk? Is this the right way?<br>What XMPP server I need to use? I read about ejabberd, openfire, tigase, ... what XMPP server is compatible with asterisk and OpenSips?<br>
Do i need a external presence server for this or its enough with OpenSips integrated?<br>When The phone is registered in OpenSips, does OpenSips inform of this to XMPP server? I don't understand well the relationship between presence and XMPP...<br>
Maybe I don't need XMPP and only with a presence server is enough?<br><br>another off-topic question. When my users are registered in OpenSips I can not use the asterisk call-pickup (*8) somebody knows how to solve that?<br>
<br>thank you very much for your help and please excuse my bad English and beginner questions,<br><br>Carlos Oliva<br clear="all"><br>-- <br><br><br><div><div style="font-size:13.3px;font-family:Verdana,Arial,Helvetica,sans-serif">
