Hi, Section 3 of RFC 3262 mentions "The UAS MAY send a final response to the initial request before having
received PRACKs for all unacknowledged reliable provisional responses, unless the final response is 2xx and any of the unacknowledged reliable provisional responses contained a session description." In a scenario the reliable 1xx did not have SDP and we go ahead and send 2xx for Invite without waiting for Prack. What if the Prack for the relaible 1xx we receive has an offer? Invite (SDP)------> <------- 180 (no SDP) <------- 200 Ok for Invite (No SDP) Prack (SDP)------> <------ 200 OK(SDP) By sending the offer in PRACK user wanted to re-negotiate the parameters, but in this case we have already sent 2xx for invite and other side will respond with ACK and the session will be established as per SDP exchange in Invite and 1xx. How does above statement mentioned above from the RFC take care of this scenario?? Will be grateful to have some direction from you on this..
