From: Stefan Sayer <[EMAIL PROTECTED]> The offerer may change the stream, but the answerer?
Uh, yes. I answered a different question than was asked. In regard to how the answer may be different from the offer, the rules are in section 6.1 of RFC 3264. In many cases, the answerer may add media formats. E.g., For streams marked as sendrecv in the answer, the "m=" line MUST contain at least one codec the answerer is willing to both send and receive, from amongst those listed in the offer. The stream MAY indicate additional media formats, not listed in the corresponding stream in the offer, that the answerer is willing to send or receive (of course, it will not be able to send them at this time, since it was not listed in the offer). In any case, if one is trying to debug SDP, one should have read RFC 3264 carefully. From: Stefan Sayer <[EMAIL PROTECTED]> And then, if you change any part of the SDP, you must update (increase) the session version, which in both SDPs of the two 200s is 1294106766. Interestingly, though the offers are identical, the answers are different (and so should have different versions).
