UA1 should follow RFC 3264 section 8 (it is also discussed within RFC 6337 section 5.2.5). The SDP can be the same as sent within the failed reINVITE and cause a session modification. You also may be interested in RFC 6337 since it discusses re-INVITE failures. _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
