Hi Colin, A couple of comments/questions on RTP/DCCP (excuse me if I'm asking questions I asked before, but if I did, I'm still unclear on the answers): Section 4.1 has a todo about supplying more direction on the implementation of congestion control in an RTP app -- what do you have in mind here? Section 4.3 Multiplexing Data and Control -- do we need to create a rule for RTP that says RTP payload types must not conflict with RTCP packet types? Or are we relying on the user of a particular profile to know if overlap exists and therefore open two connections? Section 4.4, RTP Sessions and DCCP Connections -- I'm a little unclear on the meaning of "RTP session", in particular the relationship of session to synchronization source. Is this meant to allow, for example, two PSTN gateways multiplexing media for several calls over the same DCCP connection? Tom P.
