As per my understanding, it comes because of A-party cancellation of call ... 487 is the true cause code in SIP where as 100 (when we observe as cause code) means while trying message it got cancelled by A-Party...where as if we get 180 (ringing message) then it means A-Party (calling party) cancelled the call during ringing.
