I have a question on the same lines. Lets say INVITE and 183 had an offer and answer. Is it possible for 200 response to have a new offer? For example 183 has SDP of a Media server (different IP)which plays an announcement. Then user answers with 200 OK, can this be a new SDP -offer?

I considered that scenario but for some reason assumed that the call would normally be "answered" by some kind of media server to provide that service. Now I think about it, your way makes more sense.
