OPTIONS is not very useful, I've checked that lots of UA's always reply 200 OK to an in-dialog OPTIONS even if that dialog doesn't exist. SessionTimers use re-INVITE/UPDATE, and in case of using re-INVITE it's safe since any current UA replies 200 if the dialog exists and 481 if not. -- Iñaki Baz Castillo _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
