Hi folks,
If a UAC sends a CANCEL request to the UAS, is the UAS under any
obligation for the order in which it sends it's responses? i.e.:-
It must send the 200 OK for the CANCEL before it sends the 487 for the
INVITE request.
or
It must send the 487 to the INVITE before it sends the 200 OK for the
CANCEL request.
Having a look at section 9 of RFC 3261, it makes no mention of this
which I assume implies that either situation should be dealt is acceptable.
Thanks in advance for any help supplied.
Regards,
Steve
