The UA should remember that it wants to cancel this call, and if a non-100 1xx response arrives, then it should send a CANCEL for the INVITE. If a 2xx response arrives, it should send a BYE for that dialog. Failure responses do not require any further processing, of course. The UA should indicate to the user that the call has been abandoned and allow the user to initiate another call.
