Abstract
System and method for deriving call routing information utilizing a network control data base system and voice recognition for matching spoken word sound patterns to routing numbers needed to set up calls. Public access is provided to a common database via a common access number or code. Terminating parties sponsor the call and originating parties need not be pre-subscribed to use the service. The common access number is used to initiate or trigger the service. The system advantageously operates under the direction of a service control point, which combines technologies for switching, interactive voice response, and voice recognition with the data base to automate the processes of assisting callers in making calls for which they do not know the phone number. Usage information is gathered on completed calls to each terminating party for billing. Three alternative deployments in the U.S. telephone network are described, and vary based on the location of the service control points or intelligent processors and the degree of intelligence within the network.
