A mobile switching center comprising:

• a communication interface that communicates with a wireless device;
• a voice circuit coupled to the communication interface that controls voice communication with the wireless device;
• and
• an interworking circuit coupled to the communication interface that controls at least one of data and facsimile communication with the wireless device;
• a public switched telephone network (PSTN) interface that couples the mobile switching center to a PSTN;
• and
• a service code circuit that converts a service code received from the wireless device to a pilot number;
• wherein the communication interface is configured to communicate the pilot number and a destination number over the PSTN to a destination wireless communication network to provide a service code designation to the destination wireless communication network.
