Ah, OK.
Since in my case I think the goal is to terminate the call, then I think this answers the question. I could see how the original question was somewhat ambiguous though. Thanks for the pointer..

So, just to be more explicit: the case is where the following happens
A ---> B (INVITE) A <--- B (TRYING) A <--- B (RINGING) A <--- B (OK) A ---> B (ACK) A <--> B (RTP) A ---> B (re-INVITE) A <--- B (TRYING) A ---> B (???) Cancel, or Bye?
If you want to terminate the entire call, then I think you can send a BYE. If you want to terminate the reinvite and thus reinstate the call as it was before the reinvite, then you must send a CANCEL.
AFAIK, you can send a BYE within the dialog any time after the initial ACK has been sent.

Hi David,
If you want to do a re-invite for the case where You did not get the final response (2xx) but only provisional response
than you should send "CANCEL" .

Hi All,
What is the correct thing to do on a re-INVITE. If we want to terminate the call but we have not yet received the final 2xx response for the re-INVITE, do we send a BYE or a CANCEL?
I am thinking BYE (since the re-INVITE is within a dialog), but am not sure.
