Per RFC 3261, 15 Termination a Session: The caller's UA MAY send a BYE for either confirmed or early dialogs, and the callee's UA MAY send a BYE on confirmed dialogs, but MUST NOT send a BYE on early dialogs.
How could a caller's UA send a BYE for early dialogs? The caller's dialog is transmitted to confirmed state only after receiving a 2xx for INVITE. If the caller's UA wants to terminate the session before the final response, a CANCEL should be sent out instead of a BYE. Then in which case will the caller's UA send a BYE for early dialogs?
