XO Communications Unveils Enterprise SIP Communications Solution for Distributed Enterprises

XO Enterprise SIP Simplifies, Streamlines and Reduces Costs of Managing IP Voice Across Distributed Enterprise Networks

Centralized VoIP Architecture Cost-Effectively Extends VoIP Across Enterprise, Eliminates Need for Multiple PBXs and Local Voice Trunks, and Enables Dynamic Sharing of Voice Calling Capacity Across All Locations

HERNDON, VA--(Marketwire - December 1, 2009) - Multi-location businesses can now simplify, streamline and achieve better cost savings for their networks with a new enterprise-class, multi-site SIP trunking solution unveiled today by XO Communications (OTCBB: XOHO). XO Enterprise SIP is a powerful communications solution that gives customers the flexibility and scalability to transform their distributed voice network architecture to a more centralized and cost-effective VoIP solution.

"Businesses are looking to eliminate unnecessary capital expenses and reduce operating costs related to managing voice services and equipment at each location across their enterprise, and XO Enterprise SIP solves these issues with the simplicity and bottom line benefits they are seeking," said Vince Margiotta, vice president of product marketing at XO Communications. "XO Enterprise SIP eliminates the inefficiencies of legacy voice services in a managed IP network environment. Control is centralized, complexity is reduced, and the inherent flexibility of IP can extend new features and capabilities when and where they are needed."

XO Enterprise SIP enables customers to leverage the power of a centralized IP-PBX in one or a few primary locations and deliver VoIP services to other branch locations across their existing wide area network (WAN) or using the XO MPLS IP-VPN solution. This eliminates the need for costly local voice trunks, equipment and maintenance costs at each location and centralizes local calling capacity through a single SIP-based connection at one or more primary locations.

Companies also benefit from the ability to dynamically share voice trunk capacity across their enterprise network and burst above their purchased capacity when necessary. XO Enterprise SIP enables customers to configure communications capacity across their entire network and provide each location on-demand access to unused trunk capacity from other locations when it is needed. This dynamic capability helps companies achieve maximum efficiency and reduce the number of local voice trunks required across their enterprise network.

The features of XO Enterprise SIP offer businesses a number of benefits including:

--  Lower Total Cost of Ownership by using a single or fewer IP-PBXs to
    support all locations;
--  Reduced Operating Costs by not having to maintain costly PRI
    facilities or local voice trunks at each location, and eliminating the
    operating expense of managing separate voice and data networks;
--  Greater Flexibility by allowing locations to burst above their normal
    call capacity and sharing idle voice trunk capacity from other locations
    across the enterprise;
--  Increased Efficiency in network management through simplified and
    converged network operations, significantly less effort to connect new
    locations to the public switched telephone network;
--  Business Continuity with redundant Enterprise SIP connections and the
    ability to automatically re-route calls to alternate locations; and
--  Extensive Nationwide Availability of XO VoIP services in all 50 states
    and more than 2,700 cities.

"Today's enterprises face a range of issues when managing voice services across their distributed networks, including the costs of supporting multiple communications systems, achieving the greatest cost-savings for local and long distance calling, and supporting the unpredictable call capacity needs of every location across their enterprise network," said Rebecca Swensen, Analyst at IDC, covering IP Communications Services. "Solutions such as these help multi-location businesses overcome these challenges by enabling them to centralize their IP-PBX in a few primary locations, provide VoIP services to locations, and dynamically share unused voice trunk capacity across the enterprise."
