Regarding the following comment, I am not sure of the need to send a BYE on receipt of a 481. The BYE will also elicit a 481, since the UAS has no knowledge of the dialog. Why is it a SHOULD for 481?

Request processing needs to be atomic or things get incredibly complicated.

However, certain non-2xx responses can trigger the uac to send bye. In particular, 408 and 481. This is documented in 12.2.1.2 of bis-05. -Jonathan R. -- Jonathan D.
