A communications system includes a switch that is coupled to a telephone network and is configured to determine presence of a dialing prefix of a call. The system also includes a gateway that is coupled to the data network and configured to communicate with the switch. The switch selectively routes the call based upon the presence of the dialing prefix to the gateway.
