> Question is "Is It OK/Valid to have a message body in BYE or not?"
It is valid (although if received Accept header, you might want to check it before including the body). RFC 3261 table 2 shows Content-Type with a * for BYE. Additionally, 3GPP TS 24.647 mentions sending "application/vnd.etsi.aoc+xml" body within a BYE. _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
