  • Patent number: 8194842
    Abstract: The present invention provides a method and system for implementing feature interactions between an AIN-based service and a switch-based call-forwarding service. In the present invention, the switch-based call-forwarding generates an Off-Hook Delay (OHD) trigger. In response, the SSP suspends call processing and sends the forward-to number to the SCP. Based upon the SCP's determination of whether the forward-to number is for voicemail and other criteria such as time of day, day of the week, etc, the SCP determines whether the switch-based call-forward should be permitted or inhibited.
    Type: Grant

  • Patent number: 6678515
    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.
