No, I did not. So, what's unclear about it? You can either have an option to use several codecs within one RTP stream (by accepting more than on payload type in the SDP answer), or establish *two independent* RTP streams with different codecs in each of those streams. What I am talking about is exchange as follows: Alice to Bob: SDP offer: m=audio XXXXX RTP/AVP 18 8 0 Bob to Alice: SDP answer: m=audio YYYYY RTP/AVP 0 18 Regards, -- Maksym Sobolyev Sippy Software, Inc.
