Thanks.

TelephonyManager telephonyManager;
PhoneStateListener listener;
telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);

listener = new PhoneStateListener() {
        @Override
        public void onCallStateChanged(int state, String incomingNumber) {

        switch (state) {
        case TelephonyManager.CALL_STATE_IDLE:
            Toast.makeText(SudokuGameActivity.this, "IDLE", Toast.LENGTH_SHORT).show();
          break;
        case TelephonyManager.CALL_STATE_OFFHOOK:
         Toast.makeText(SudokuGameActivity.this, "OFF Hook", Toast.LENGTH_SHORT).show();
          break;
        case TelephonyManager.CALL_STATE_RINGING:
            Toast.makeText(SudokuGameActivity.this, "Ringing", Toast.LENGTH_SHORT).show();
            mpauseButton.performClick();
          break;
          }

        }
       };

Have you written the following line :

 telephonyManager.listen(listener,PhoneStateListener.LISTEN_CALL_STATE);
