I wonder why re-INVITEs are treated different (if indeed they are). I
believe this could cause other problems, as section 12.2.2 of the RFC
states: "Requests sent within a dialog, as any other requests, are atomic.
If a particular request is accepted by the UAS, all the state changes
associated with it are performed. If the request is rejected, none of the
state changes are performed."
In my case, my application is a B2BUA. I've noticed this problem in a
scenario in which the call is established and the receiving end generates a
re-INVITE. The originating end answers with the 480, which is ACKed, and
then nothing happens. The end that generated the re-INVITE chooses not to
disconnect the call and the conversation should still be going on. What
happens next is that after some time, the original caller chooses to hang
up, and sends a BYE. nua correctly answers the BYE, but when my application
tries to hang up the second leg (the one that received the re-INVITE),
nothing happens and the receiving end wastes resources until the person
decides to hang up too because of the lack of audio.

I'd appreciate that very much as I believe this is a fairly serious problem
in our scenario.
Thanks a lot.
