Dear Paul: Thanks for you explanation. And I want to know more specifically on this topic.
In your summarizing, it says "an offer always contains what the offerer *wants*", but what if the offer's "wants" is ambiguous? B receives "sendonly" and responses "recvonly" passively, and B doesn't indicate further behavior (hold or resume). In fact, B wants nothing, B is just held there. If B needs to play the role of offerer in 200 OK response followed re-invite from A with empty sdp, should B treat that as a new SDP negotiation and return the full capabilities? BR, thanks very much.
