Abstract
The presently disclosed architecture enables a service provider to support public voice VPN services over an IP VPN network. The architecture utilizes a customer VPN, a designated gateway for the customer VPN, an IP VPN transport network, and a Call Control Element/router Complex which uses IP technology to map between the IP VPN and the voice VPN. With such an arrangement, the customer VPN is extended to the gatekeeper of the Call Control Element/router Complex, thereby enabling the provision of voice VPN services over an IP network.
