Hi, I think mostly UA shall send CANCEL after receiving 180 Ringing. If it sends CANCEL, RFC 3261 Chapter 9.2 reads like...
>>>>>>>>>>>>>>>>>> RFC 3261 Chapter 9.2 >>>>>>>>>> " The CANCEL method requests that the TU at the server side cancel a pending transaction. The TU determines the transaction to be cancelled by taking the CANCEL request, and then assuming that the request method is anything but CANCEL or ACK and applying the transaction matching procedures of Section 17.2.3. The matching transaction is the one to be cancelled" >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Regds, Somesh S.
