Hi, I have a SIP question about Figure 5 "INVITE client transaction" in RFC3216 http://www.ietf.org/rfc/rfc3261.txt. It looks to me when the transaction is at "Proceeding" state (i.e.: after client receiving the 1xx response), the only way to move the transaction to next state is to receive final response (200-699). Then what happen if final response is lost, would the client transaction be stuck in this state forever and never terminated? By looking at the text description in section 17.1.1.2, I could not find any clear statement say Timer B should continue at this state or not. How it works if there's no timer? If someone can help me, much appreciated.
Thanks, Yong _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
