-     * Initiate emergency voice call, with zero or more emergency service category(s), zero or
-     * more emergency Uniform Resource Names (URN), and routing information for handling the call.
-     * Android uses this request to make its emergency call instead of using @1.0::IRadio.dial
-     * if the 'address' in the 'dialInfo' field is identified as an emergency number by Android.
-     *
-     * In multi-sim scenario, if the emergency number is from a specific subscription, this radio
-     * request can still be sent out on the other subscription as long as routing is set to
-     * @1.4::EmergencyNumberRouting#EMERGENCY. This radio request will not be sent on an inactive
-     * (PIN/PUK locked) subscription unless both subscriptions are PIN/PUK locked. In this case,
-     * the request will be sent on the primary subscription.
-     *
-     * Some countries or carriers require some emergency numbers that must be handled with normal
-     * call routing if possible or emergency routing. 1) if the 'routing' field is specified as
-     * @1.4::EmergencyNumberRouting#NORMAL, the implementation must try the full radio service to
-     * use normal call routing to handle the call; if service cannot support normal routing, the
-     * implementation must use emergency routing to handle the call. 2) if 'routing' is specified
-     * as @1.4::EmergencyNumberRouting#EMERGENCY, the implementation must use emergency routing to
-     * handle the call. 3) if 'routing' is specified as @1.4::EmergencyNumberRouting#UNKNOWN,
-     * Android does not know how to handle the call.
-     *
-     * If the dialed emergency number does not have a specified emergency service category, the
-     * 'categories' field is set to @1.4::EmergencyServiceCategory#UNSPECIFIED; if the dialed
-     * emergency number does not have specified emergency Uniform Resource Names, the 'urns' field
-     * is set to an empty list. If the underlying technology used to request emergency services
-     * does not support the emergency service category or emergency uniform resource names, the
-     * field 'categories' or 'urns' may be ignored.
-     *
-     * In the scenarios that the 'address' in the 'dialInfo' field has other functions besides the
-     * emergency number function, if the 'hasKnownUserIntentEmergency' field is true, the user's
-     * intent for this dial request is emergency call, and the modem must treat this as an actual
-     * emergency dial; if the 'hasKnownUserIntentEmergency' field is false, Android does not know
-     * user's intent for this call.
-     *
-     * If 'isTesting' is true, this request is for testing purpose, and must not be sent to a real
-     * emergency service; otherwise it's for a real emergency call request.
