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.
