Yes, under the current model it would. It's not a necessary scenario to have the same Session-ID, IMO, but it's covered that way.

Will they ever have the same Session-Id? As currently defined no, it would not. I talked to some people about that at the IETF meeting, and they thought that was the right thing to do, as do I; but we couldn't define a textual explanation of what properties made that right. > Also, how are dialog event packages supposed to work?

As an optional XML element update to them, which only gets used for matching if the call-id element did not match. -hadriel _______________________________________________ Sip mailing list https://www.ietf.org/mailman/listinfo/sip This list is for NEW development of the core SIP Protocol Use [EMAIL PROTECTED] for questions on current sip Use [EMAIL PROTECTED] for new developments on the application of sip
