Gurus, If party-A in a call wants to put the other party(B) on hold, it should reinvite that party with a sendonly media stream offer. Party-B answers with a recvonly media stream - the media is now one-way from A to B. Typically, according to RFC3264 section 8.4, party-A should locally mute.
However, the question arises when dealing with e.g. music on hold and call-progress tones. In the situation described above, party-B would be responsible for generating a call-progress tone locally. But if party-A would not mute, but instead send media (music on hold or whatever) party-B should not generate call-progress tones. Is there a general way for party-B to decide to either generate call-progress-tones or to play the media? Thanks, Martin. _______________________________________________ Sip-implementors mailing list [email protected] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
