Voice Over Internet Protocol

By adopting VoIP VPNs, enterprises can set up company-wide VoIP-based communications without the need for point-to-point connections between facilities. As a result, enterprises can achieve increased flexibility and decrease their operating expenses substantially. Unlike traditional separate meshed voice and data networks, each site requires only a single converged access link to a service provider's VPN-enabled network.
