Whenever the X-lite sends a CANCEL to a Cisco gateway after having received a 183 Session Progress, the gateway sends back a 481 Call Leg/Transaction Does Not Exist. This way, the call is not being canceled as the called phone will keep ringing. If no 183 Session Progress is received, the call is normally canceled.
