XO Communications' SIP Solution Now Rated "Avaya Compliant"

Updated: March 24, 2011

XO Communications today announced that its XO SIP service is compliant with Aura™ Communication Manager and Avaya Aura™ SIP Enablement Services from Avaya, a leading global provider of business communications applications, systems and services.

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. XO SIP uses Session Initiation Protocol signaling and a native IP-based facility to manage all traffic between a customer's IP-PBX 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 eliminating 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 Flex, IP Flex with VPN and XO SIP locations
• Long distance calling with choice of calling plans
• Optional Voice Compression
• Online Feature Management through the XO Business Center

XO SIP now is compliance-tested by Avaya for compatibility with Avaya Aura Communication Manager 5.2 and Avaya Aura SIP Enablement Services 5.2. In addition, XO Communications had previously completed interoperability testing with XO SIP and Avaya Communication Manager 5.1 and SIP Enablement Services (SES) 5.1 and Avaya IP Office 4.2.4.

"Businesses are looking for high-performance communications platforms that are easy to deploy, manage and have the flexibility to incorporate new technology in the most cost-effective manner possible," said Vince Margiotta, vice president of product marketing at XO Communications.

"Together, Avaya and XO Communications can help enterprises get even more out of their communications investments and ensure existing and new communications infrastructure can work seamlessly together to connect users, applications and systems."

XO Communications is a member of the Avaya DevConnect program -- an initiative to develop, market and sell innovative third-party products that interoperate with Avaya technology and extend the value of a company's investment in its network.

As a Gold/Platinum member of the Avaya DevConnect program, XO Communications is eligible to submit products for compatibility testing by the Avaya Solution Interoperability and Test Lab. There a team of Avaya engineers develops a comprehensive test plan for each application to verify whether it is Avaya compliant. Doing so ensures businesses can confidently add best-in-class capabilities to their network without having to replace their existing infrastructure -- speeding deployment of new applications and reducing both network complexity and implementation costs.

"By participating in Avaya's compliance testing program and committing to open standards, development partners like XO Communications are helping businesses get more out of their network investment," said Eric Rossman, vice president, developer relations and technical alliances, Avaya. "Our customers are able to easily communications-enable critical business processes, change the way they work and uncover new value that can help them build their bottom line."
