It is not exactly a SIP Proxy's job, but rather a IM Server's (Messaging Server) Job. The Proxy Server should help in establishing the IM Conference. It is a procedure defined in OMA IM Conference package. The initiating UA will send an INVITE with a special xml payload Content Type "application/resource-lists+xml" in addition to the SDP. The Proxy/IM-Server up on receiving this INVITE will proxy the INVITE to all registered UA found in the resource-lists xml that was received in INVITE. All the UAs who are referred will then send INVITE and join in the IM Conference that was created by the originating IM UA. The media is done using MSRP and MSRP relay independent of the Proxy Server. The Proxy/IM-Server only help in establishing the SIP IM-Conference. No media will be handled by the proxy as in case of any other conf/session. ALl the IM/Proxy server that supports IM -COnf will have a predefined Ad-Hock IM COnf URI like "<a href="mailto:IMConf@opensips.com">IMConf@opensips.com</a>". All IM COnf will gets established by sending INV to this special URI.<br>
<br>AG Projects public opensips server does support this feature. Wondering if opensips already have this ? or in future roadmap ?<br><br>Thanks in Advace.<br><br><div class="gmail_quote">On Mon, Nov 2, 2009 at 2:10 PM, Iñaki Baz Castillo <span dir="ltr"><<a href="mailto:ibc@aliax.net">ibc@aliax.net</a>></span> wrote:<br>
