Yes, I aunderstand that (the different "To tag" in a 200(CANCEL) from a stateful proxy and from a UAS). By my question is: Why "To tag" is needed in that 200 OK? CANCEL matches a transaction, not a dialog. -- Iñaki Baz Castillo [EMAIL PROTECTED] _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
