ABSTRACT:
A system and method that enables callers to dial a subscription code instead of a telephone number to reach a subscriber of the subscription code. The system includes a lookup table that associates the subscription code with the subscriber's telephone number. The system also uses a routing device that is in communication with the lookup table. The routing device is adapted to receive calls that were initiated by callers using the subscription code. When a call originated by a caller using the subscription code is received by the routing device, the routing device reviews the lookup table to retrieve the telephone number that is associated with the subscription code. The telephone number is then used by the routing device to terminate the call to the telephone number.
