System and method for providing call management services in a virtual private network using voice or video over internet protocol

A system and method for providing a private telephone network using Voice over Internet Protocol includes an addressing scheme that supports two levels of numbers, an Internet name that identifies individual users and a Directory number, which allow the network supported by a plurality of switches to function as if the multiple customers are being served by a single switch. The system of the present invention includes a gateway in communication with both a Public Switch Telephone Network and users of the private network; a call agent in communication with the gateway for processing different requests received at the gateway; a server-based interface including a Directory Server for translating between the Internet name (Network Address) and a Customer address and a Domain Name Server for translating between the Internet name (Network Address) and an Internet Protocol Address.
