Abstract: A method and system state-of-the-art private VoIP network for delivery of high quality, lower cost voice and data services to business customers across the United States. The unique implementation of the latest networking and Internet technologies over a privately managed network produces Quality of Service that rivals traditional circuit-switched calls and allows customers to capitalize on the convergence of traditional circuit-switched voice networks with packet-based networks. Proprietary account management, call detail recording, and accounting software complements the equipment and satisfies the administrative needs of business customers. Customers receive the added security and flexibility of “virtual private networks” through the implementation of IP technology, advanced switching equipment, and Asynchronous Transfer Mode (“ATM”) operation of the fiber optic backbone.
