Hi All, Section 13.2.2.4 of rfc 3261 says that " If the offer in the 2xx response is not acceptable, the UAC core MUST generate a valid answer in the ACK and then send a BYE immediately"
I have some question on this behavior: 1) If the offer being presented in 2xx (200 OK) for INVITE is not acceptable by UAC, what would be the valid answer in that ACK? Remember this not re-INVITE which will have prior SDP. 2) if same offer is not acceptable by UAC, it means there is no media streams. Why send valid answer in ACK when offer is not acceptable ? Again sending BYE immediately means terminating the session? If you are sure to terminate the session soon, why to send answer in ACK? Shouldn't UAS consider that ACK has never been received and UAS send BYE rather than UAC? I know the questions are multifolds rather twisted a lot, please try to anwer my queries. -- Nabam Serbang _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
