Hello, i have a question about the following scenario. Suppose an unicast session is established between A and B, and there is at least one B2BUA on the signaling path.
Suppose also B is sending RTCP Goodbye any time it wants to modify the session (e.g. before sending a re-INVITE with a new codec). Now think about the following re-INVITE sequence from B to A (session is established in G.729). 1) re-INVITE from B to A with G.711 only 2) re-INVITE from B to A for T.38 --> A sends 488, session reverts back to the state prior to the Offer, for which an RTCP Goodbye has been sent 3) re-INVITE from B to A with G.711 only (exactly the same SDP as step 1) --> B2BUA directly answers 200 OK including the already negotiated SDP from A side, so A doesn't receive the latest re-INVITE --> since RTCP Goodbye was sent, there is no active stream and A won't receive RTP packets sent by B Has this been addresses somehow? Is it allowed to send an Offer with an unchanged SDP for a session for which an RTCP BYE has already been sent? Thanks.
