The routing rule at Index 7 appears only if the [CRPGatewayFallback] parameter is enabled (see Configuring PSTN Fallback). This routing rule is used if the device can't find a matching destination user for IP Group 1 (User-type IP Group) in its registration database. If the [CRPGatewayFallback] parameter is disabled and no matching user is find, the device rejects the call.
