Yes, but that's exactly the point. According to RFC3261, a proxy not supporting RFC 3326 could ignore the "Reason" header in an incoming CANCEL and not include it the CANCEL it generates for the pending branches. And it would be 100% valid since CANCEL is hop-by-hop. This is why RFC 3326 states a new behaviour for "Reason" header in CANCEL request (I assume). -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
