XO Reports on VOIP Traffic

RESTON, Va. -- XO Communications today announced that it carried 3.89 billion minutes of Voice over Internet Protocol (VoIP) traffic across its private nationwide IP network in the second quarter of 2006, a 34 percent increase over the previous quarter and a 140 percent increase over the second quarter of 2005. The increase was driven by greater deployment of XO VoIP solutions by businesses and service providers, demonstrating the increasing demand for delivering voice services over an all IP network environment.

"Demand for our Voice over IP services continues to grow as businesses and service provider customers accelerate their migration of voice traffic to services based on IP," said Carl Grivner, CEO of XO Communications. "Our private IP network and robust Voice over IP platform provides customers with the broad nationwide coverage and performance to meet their requirements today and in the future."

XO offers a full suite of commercial and wholesale VoIP solutions delivered over an advanced softswitch and private IP network platform powered by Sonus Networks and Juniper Networks. This platform delivers both traditional circuit-switched voice traffic and packet-based VoIP traffic, allowing XO to support customers that continue to rely on time division multiplexing (TDM) technology and those that have migrated to more advanced, IP-based voice technology. By managing the VoIP platform over its own private IP network, XO helps customers avoid the congestion and delays of the public Internet while ensuring that customers' voice traffic is delivered with the same quality and reliability of traditional telephone networks.
