It is likely best to ask the vendor of the B2BUA since we can only make assumptions concerning the configurable parameter. Years ago some were recommending to send both CANCEL and BYE (as a way to handle some CANCEL and INVITE 2xx race conditions). The mentioned configuration parameter might be related to that (unless CANCEL is not also being sent). _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
