Hi, I was wondering about a specific SIP scenario of the following type: Two SIP endpoints send invite messages to each other at the same time during the same SIP session (same Call-Leg).
(a) (b) Invite Invite --------> <---------- While this scenario is unlikely to happen, it becomes more probable if you consider that One of the (re)invites could be a result of session-expiration refresh. My question is what is the "right" way to handle this sort of situation? Remember that the two invites could completely differ in coders & SDP. Moreover, a 4xx response from one side could result with disconnection of the session, certainly an unwanted feature. In general I've never seen SIP call flaws involving two interactions at a time. I'd appreciate any suggestions or enlightening comets on the issue. Best regards, Udi Apsel. _______________________________________________ Sip-implementors mailing list [EMAIL PROTECTED] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
