Unisys Employs Quintum’s Tenor VoIP Gateway in Service Offering for Customer Trials of Microsoft’s Unified Communications Technologies

Quintum Technologies, an innovator in VoIP technologies and a subsidiary of Network Equipment Technologies, Inc. (NYSE: NWK), announced today that Unisys Corporation (NYSE: UIS) deployed Quintum's Tenor VoIP gateway in its "unified communications hosted trial" service. The service allows customers to test Microsoft Corp.'s unified communications technology at no cost, including Microsoft Exchange Server 2007, Microsoft Office Communications Server 2007, and Microsoft Office Live Meeting.

Unisys was selected by Microsoft for its deep expertise in developing communications solutions on the Microsoft platform and its ability to manage reliable enterprise-class applications. Similarly, Unisys evaluated the Microsoft-certified gateway vendors and selected Quintum based on its long term working relationship with Microsoft in providing support for Office Communications Server 2007 in the Tenor line of VoIP switches and gateways. The Tenor CMS (Carrier MultiPath Switch) was adopted because it provided back-end support for the unified communications platform and had the capacity to support a hosted platform.

Unisys developed, implemented and manages the hosted trial service in conjunction with Microsoft. The program allows Unisys and Microsoft salespeople to sign up to 20 accounts per customer to evaluate the latest unified communications technology from Microsoft for 30 days, including e-mail, calendaring, unified messaging, multi-party instant messaging, and voice and video conferencing.

"This new service allows our clients to experience the power of unified communications across their enterprises," said Jim Boak, vice president, Microsoft and Intel Alliances, Unisys. "We chose the Quintum Tenor for our trial service platform because it was easy to install, provides excellent voice quality and is very reliable."

"The ability to try the service without needing to deploy equipment will allow more companies to experience the value of unified communications," said Chuck Rutledge, Vice President of Marketing for NET/Quintum. "We are pleased to be supporting this service along with Microsoft and Unisys."
