Hi, I have a question on determination of a retransmitted request. According to rfc2543-bis-02, Section 11.5, Item 2, a request received is a retransmitted request if Call-ID, From, To and CSeq values exactly match. According to rfc2543-bis-03, Section 15.5, Item 3, a request received is a retransmitted request if Call-ID, From, To, CSeq, Request-URI, and branch-ID in the topmost Via exactly match. I'd like to understand reasons as to why we needed to add two additional fields to identify a retransmitted request. I think it may be related to the support of redirect capability or forking proxy, but i am not sure. This probably has been discussed many times before; but i haven't followed much and i'd appreciate any help anyone can provide. Thanks, YoungSun _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
