All, I am looking for the SIP standard/draft that defines how an ad-hoc conference should be initiated where the focus is not one of the original users as follows:
1) Alice is talking to Bob in a standard P2P call (RTP flowing in both directions between Alice and Bob) 2) Alice invites Charlie to join Alice and Bob in the call. (not sure how this is done) 3) After Charlie answers his phone and the media channels have been set up between Charlie and the conferencing server (which is a separate application not connected to either Alice or Bob), both Alice and Bob's call are somehow transferred to the correct conferencing resource on the conference server where Charlie will be waiting for them. In the process of Alice's and Bob's transfer the initial media channels should stay connected as long as possible before the actual transfer so that Alice and Bob will not detect any unnatural break in the audio. Thanks, Simon _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
