Abstract
In an Advanced Intelligent Telephone Network system, switching points are programmed to trigger a query to a Service Control Point ('SCP') in response to a dialed '500' number. The SCP performs a data request of an outside database storing service provider information, obtaining a service provider identification or a routing number corresponding to the dialed '500' number. The SCP then transmits a switching instruction to the service system point to route the call to the appropriate destination number.
