Hello, I need advice on SIP RFC's or drafts relevant to implementation of 3 way conf calls using distributed mixing. The idea is �that each partcipant send his media stream to all other participants using multicast or multi-unicast. �And each participant does audio mixing locally.
All SIP RFCs and drafts seems to suggest centralised mixing by conference focus which redistribute the mixed stream to other participants... I can imagine how the distributed mixing can be done using multicast (for example using re-Invites to parties with multicast address in the SDP), �but how to do it in case of multi-unicast? Suppose that endpoint A is in session with B and now B want to bring C into conference. So B send an INVITE to C and establish a 2 way call... Now B has to direct C to establish a call to A and inform somehow A and C that the newly established call is actually a part of a conference, so that A and C will be a) able to mix incoming streams and b) send data from local source to two different destinations. Any pointers or advices? Thanks Vadim _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
