Unfortunately, BYE doesn't quite work. The called UA can't send BYE until the dialog is established (after the UA has sent a final response) (per section 15, para. 1), and after a 4xx response has been sent, a dialog doesn't exist, so the UA can't send a BYE after that. The UA can get "prompt release signaling" by accepting the call and then sending an immediate BYE, but the 2xx will tend to terminate other forks.
