        <!-- CALL vs CALL_PRIVILEGED vs CALL_EMERGENCY
             We have three different intents through which a call can be initiated each with its
             own behavior.
             1) CALL - Expected from any third party app with CALL_PHONE permission. Through this
             intent, an app can call any number except emergency numbers.
             2) CALL_PRIVILEGED - Expected from the dialer app and requires CALL_PRIVILEGED
             permission, which is only held by the system dialer and the emergency dialer at the
             time of this writing. Through this intent, an app can call any number including
             emergency numbers.
             3) CALL_EMERGENCY - Expected from the emergency dialer app and requires CALL_PRIVILEGED
             permission. Through this intent, an app can call *only* emergency numbers. -->
