Hi, an easy scenario: - A calls C through a B2BUA and the call is established with direct audio between A and C.
- A sends an in-dialog OPTIONS but B2BUA replies nothing (ignores the request) due to a bad implementation or SIP stack. - After ~32 seconds A decides that the dialog is dead and terminates the call (stops sending RTP). In this case A doesn't require to send a BYE as an in-dialog request has not been answered by B2BUA so the dialog is clearly broken. Well A could generate a BYE with a very high CSeq (at least greater than the failed OPTIONS) and send it to B2BUA but it's, for sure, not required at all. My question is: could somebody please point me to the exact point in RFC 3261 in which this is explained? I need it to document a failure in a SIP device. I have no doubt about that the above is 100% correct (A is not required to send such BYE), but I have to document it and cannot find the exact specification in RFC 3261. Any reference in RFC 3261 please? Thanks a lot. -- Iñaki Baz Castillo <[email protected]> _______________________________________________ Sip-implementors mailing list [email protected] https://lists.cs.columbia.edu/cucslists/listinfo/sip-implementors
