Hi, Please let me know if my understanding is correct for regular session offer-answer when PRACK is used:
For INVITE containing SDP, and if offer answer done in the using reliable 183 response for early media, 200 OK response SDP will have an answer for the regular session, so 200 OK SDP will be answer to the offer sent in initial SDP. Similarly, if INVITE does not have SDP, and if offer-answer done using PRACK, still 200 OK will contain the regular session offer and answer will be present n the ACK message. Similarly, if UPDATE is used for offer-answer before call is connected, it will not affect the regular session offer-answer, it will be taken care by initial INVITE , final 200 OK and ACK message.
