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.
Johnny
