|  | * intent on to the {@link SipCallOptionHandler}, which will | 
|  | * ultimately start the call using the CallController.placeCall() API. |

|  | * 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. |
