I didn't go into the JS-level mechanisms used. I guess I might be missing something, but how, using ACCEPT, RTC can generate a single offer, get two answers back, and create two media streams? Creating a second media stream does not mean that this is a last answer for this stream (corresponds to new SIP dialog created by provisional response) and accepting a stream does not mean it cannot be cloned (corresponds to new SIP dialog created by new final response). So essentially we need four operations: create offer, create media stream based on an answer, update existing stream based on a new answer for the same dialog, and finalize the media stream. Or alternatively we can achieve the same with create offer and stream together, process answer, accept (finalize the stream) and clone the stream. Either way we need four methods and we achieve the same functionality.

I did not realize we are requiring DTLS/SRTP in RTC. I don't think I've seen a single implementation of this in the wild, and I do not see any harm in supporting SRTP and (with user confirmation) of plain RTP. _____________ Roman Shpount
