Hi,
> RFC 3261 sec. 13.2.1 says that a UAC MUST treat the first session > description it receives in a reliable non-failure message as the answer, > and MUST ignore any session descriptions in subsequent responses to the > initial INVITE. Does it mean that if 183 has SDP in response to Invite's > offer, it should be treated as answer and SDP in 200 OK be ignored? Yes, assuming that the 183 was sent reliably (using PRACK), AND that the 200 is received within the same dialog as the 183 (the INVITE may have been forked to multiple servers).
