Abstract

See full text

A virtual private communications network (VPCN) and method of managing calls on the network. Stations on a private communications network are identified by an unique private network identification (ID) code or dial in direct (DID) number. Remote communications devices (e.g., cell phones, analog phones, etc.) are virtual client devices connected from a public communications network to the private communications network. One or more DID numbers are shared DID numbers, dedicated for the virtual client devices. Calls from the virtual client devices may be placed to network stations by dialing shorthand (e.g., 5 or fewer digits) numbers. Each call has a dedicated DID number temporarily assigned to it for placing the call as an in network call. Once the call reaches its final destination, the shared DID number is released for temporary assignment to other virtual client device calls.
