+ * OutgoingCallBroadcaster receives CALL and CALL_PRIVILEGED Intents, and broadcasts the
+ * ACTION_NEW_OUTGOING_CALL intent. ACTION_NEW_OUTGOING_CALL is an ordered broadcast intent which
+ * contains the phone number being dialed. Applications can use this intent to (1) see which numbers
+ * are being dialed, (2) redirect a call (change the number being dialed), or (3) prevent a call
+ * from being placed.
+ *
  * After the other applications have had a chance to see the
  * ACTION_NEW_OUTGOING_CALL intent, it finally reaches the
  * {@link OutgoingCallReceiver}, which passes the (possibly modified)
  * intent on to the {@link SipCallOptionHandler}, which will
  * ultimately start the call using the CallController.placeCall() API.
  *
- * Emergency calls and calls where no number is present (like for a CDMA
- * "empty flash" or a nonexistent voicemail number) are exempt from being
- * broadcast.
+ * Calls where no number is present (like for a CDMA "empty flash" or a nonexistent voicemail
+ * number) are exempt from being broadcast.
+ * Calls to emergency numbers are still broadcast for informative purposes. The call is placed
+ * prior to sending ACTION_NEW_OUTGOING_CALL and cannot be redirected nor prevented.
