ABSTRACT:
An Active User Registry system includes a database which is integrated with the POTS network and a packet network to exploit the outstanding strengths of both of its constituents. The Active User Registry database is a dynamic data structure of all the ways in which one or more users can be reached via some type of communication network. A key feature of the Active User Registry is the ability to broker between a subscriber's request for communications contact information corresponding to a user and the user's preferences of being reached by various communications alternatives.
