In a UAS 500 means "UAS internal error", so it's never a proper response. 488 is the correct choice. A response is defined at transaction level, so an INVITE and re-INVITE are the same when coming to generate a response. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
