Abstract
A telecommunications system determines a routing preference of a telecommunications service provider for a telephone call from a calling party to a called party. A switch in the telecommunications system includes a signal generator that generates a signal in response to receiving the telephone call. The signal includes a service variable and a telecommunications service provider identifier. The service variable indicates a subscription-type for a telephone number associated with the calling party or the called party. The signal is used to determine the routing preference at a service control point in the telecommunications system. The service control point receives the signal from the switch and determines the routing preference. The routing preference is forwarded to the switch. The switch receives the routing preference and routes the telephone call according to the routing preference.
