Sounds okay; however the CANCEL is typically still needed to cancel the INVITE 
(when appropriate) since the BYE received on early dialog isn't adequate to 
communicate/trigger cancellation of INVITE.

The lack of CANCEL can trigger useless forking by proxy/b2bua upon receiving 
INVITE 487 (or other failure response because BYE) when the caller no longer 
cares about INVITE.
