ABSTRACT:
The multiple location, communications network is provided as an overlay application to, for example, one or more private networks. The network adds increased flexibility to an existing private network system by adding additional features, e.g., abbreviated dialing plans, function number dialing, automatic selection of routing, centralized access to private and public network facilities, outgoing call screening, and work-at-home functionality, that may not be currently available to the private network subscriber. Further, the network overlay application of the present invention is adapted to maintain and not disturb the subscriber's current service or the existing private network.
