Hi Attila, One way could be to verify for magic cookie ( z9hG4bK ) in bottom most via header. If there is no magic cookie, then it is a 2543 compatible UE.

An RFC 2543 re-INVITE could have just a From tag, just like an RFC3261 INVITE. So, how to distinguish between an RFC2543 re-INVITE and an RFC3261 INVITE?
