Hi,
 
I have a question. Suppose the situation that two users (A, B) are connected.
Then user A sends re-INVITE to user B, but before it receives a response it decides to hang-up.
My question is: can user A send BYE just after the re-INVITE or it should wait for a response on the re-INVITE (and send ACK before)?
 
My understanding is that according to draft (bis09) it is possible to send INVITE and BYE, since BYE is a regular transaction and as that it can be send while INVITE is in progress. Is that right? If so, how would user B behave in this situation?
 
Regards,  Jirka
