Abstract

A method and system for conditionally forwarding a call for use in a communication network including a switching center in communication with at least one alternative system, and a plurality of subscribers, each subscriber having at least one directory number. The method includes providing a service location register in communication with a switching center, the service location register operative to retrieve stored call termination parameters for each of the subscriber's directory numbers and call information for each incoming call to a directory number, the call termination parameters including call forwarding features. A busy or no answer condition is detected for a call to a directory number and the request is forwarded to the service location register for routing instructions. Service logic is applied to disconnect the call or route the call to at least one alternative system.
