Hi, I'd like to clarify some facts concerning INVITE transactions which contain an early media response e.g.
INV--> <--183 <--200 ACK--> Is it permissable/possible for the 200 OK to negotiate different SDP than the SDP negotiated in the 183? That is, is:- INVITE ... m=audio 6980 RTP/AVP 18 8 4 0 183 ... m=audio 4780 RTP/AVP 18 8 200 ... m=audio 4790 RTP/AVP 4 0 ACK a valid exchange?
