Re: [SR-Users] [OT] IETF SIMPLE WG will destroy MSRP with the new draft-ietf-simple-msrp-sessmatch-11

2011/5/26 Iñaki Baz Castillo <ibc(a)aliax.net>et>: And also, IM real conferences are already defined using MSRP and a focus conference MSRP server (I've seen it working pretty well: - An UAC sends an INVITE with SDP containing MSRP offer to a server (the destination is a conference SIP AoR). - The conference server replies 200 OK and includes a ;focus parameter in the Contact. The IM session between the UAC and the server is already established. - As the 200 Contact contains ;focus parameter, the UAC can subscribe to the server (Event: conference) and receives a NOTIFY with the participants, and receives more NOTIFY's each time a participant is writting or talking (you can render it in your UA screen) => RFC 4575 (valid for voice/video conferences and IM-MSRP conferences). - New participants (or leaving participants) are notified in next NOTIFY's from the server. - This is cool. I wonder how all of this could be accomplished with MESSAGE request without producing N news specifications. Or don't we want IM conference? do we assume that our SIP client will use XMPP for advanced IM features? Not me. Regards. -- Iñaki Baz Castillo <ibc(a)aliax.net>
