XO Communications Announces Cisco Unified Communications 500 Series and XO SIP Have Passed Tests for Interoperability

XO SIP and Cisco Smart Business Communications System Provide Small Businesses With Cost Savings and Enhanced Productivity

HERNDON, VA--(Marketwire - April 16, 2008) - XO Communications (OTCBB: XOHO), a leading provider of 21st century communications for businesses and communications service providers, today announced that its award-winning XO SIP service has passed interoperability tests with the Cisco Smart Business Communications System, the industry-leading unified communications system designed for small businesses.

The successful interoperability certification of these two solutions enables small businesses to simplify the overall deployment and management of their IP telephony services with peace of mind that the two solutions will interoperate effectively.

"XO Communications recognizes that businesses need to focus on running their business, not spend precious time and resources on their voice and data communications services," said Nicola Jackson, director of IP and converged services at XO Communications. "XO SIP's interoperability with the Cisco Smart Business Communications System allows businesses to capitalize on their investment by seamlessly linking their IP voice and data services with their PBX system, resulting in less time managing the network and more time conducting business."

"Cisco is excited to collaborate with XO Communications to continue to drive unified communications with a managed SIP trunk solution," said Mark Monday, vice president of product marketing for Cisco Unified Communications. "The Cisco Small Business Communications System (SBCS) includes the Cisco UC500 and offers a complete solution for SMBs to interconnect to a high-quality network, which will also provide additional voice and data services for those SMBs."

Cisco Smart Business Communications System offers small businesses a simple, affordable, easy-to-manage unified communications system, eliminates multiple servers and combines voice, data, voicemail, Automated Attendant, video, security, and wireless capabilities. It also supports the portfolio of Cisco Unified IP Phones, Internet connectivity with firewall protection, virtual private networks (VPNs), and wireless LAN access for reliable, highly secure communications. Combined with its optional desktop application support, Cisco Smart Business Communications System enables more effective collaboration by using simple yet powerful capabilities such as instant messaging, single-number reach, and desktop control of all calls and messages to help enrich the total communications experience.

XO SIP is a fully integrated solution designed to support the needs of businesses with the most demanding voice and data applications at single or multiple locations. Session Initiation Protocol uses a native IP-based facility to manage all traffic between a customer's IP-PBX system such as the Cisco Smart Business Communications System, the XO IP network, and the Public Switched Telephone Network. The service provides greater efficiencies by eliminating the need for businesses to maintain multiple access facilities for voice and data services and eliminates the need for bandwidth-consuming protocol conversions.

XO SIP includes a broad range of bandwidth options to maintain optimal network performance and has the following features:

--  Dedicated Internet access with dynamic bandwidth allocation
--  Unlimited local calling
--  Unlimited site-to-site calling for multi-location customers with IP
