XO Communications, Inc. announced that it is providing wholesale voice over Internet Protocol (VoIP) termination services to SunRocket, one of the nation's leading Internet phone service providers.

SunRocket is utilizing XO VoIP Termination to support its rapidly growing all-inclusive Internet home phone service. XO VoIP Termination enables SunRocket to hand off voice traffic to XO, allowing SunRocket's customers' IP- based calls to be routed across the XO IP network at the highest priority and terminated to the public switched telephone network at destinations across the United States.



"SunRocket delivers reliable, best-of-breed services to our customers, and choosing the right network partners ensures that we continue to provide that outstanding quality of service, including enhanced 911, while growing rapidly," said Rob Mainor, chief operations officer at SunRocket. "XO is a leading enabler of VoIP service providers and will enable us to broaden our network coverage and performance as we continue to rollout SunRocket service nationwide."

"SunRocket's selection of XO is another demonstration of our success in delivering advanced wholesale VoIP solutions for today's new breed of phone companies," said Ernie Ortega, president of carrier sales at XO Communications. "Providers like SunRocket are driving the adoption of innovative voice services and we are proud to be a partner for them."

XO VoIP Termination enables broadband telephony providers and cable companies to hand over their VoIP traffic directly to XO for termination to the public switched telephone network. With an IP connection to the XO IP network, customers' voice traffic is routed across the XO OC-192 class of service-enabled network at the highest level of priority. The traffic passes through an XO softswitch gateway and is carried across the XO IP network to an XO softswitch gateway nearest the final destination of the call. The traffic is then converted by an XO softswitch to a format accepted by the terminating local service provider.

XO is a leading provider of wholesale VoIP services to carriers and service providers and carries more than 1.6 billion minutes of voice traffic across its award-winning national IP network each quarter. XO offers a broad suite of commercial and wholesale voice solutions over an advanced softswitch network platform that routes both traditional circuit-switched voice traffic and packet-based VoIP traffic across the XO IP network. By managing the VoIP platform over its private IP network, XO delivers customers' voice traffic with the same quality and reliability of traditional telephone networks while avoiding the congestion and delays of the public Internet.
