EMBARQ Launches Next Generation Value-Added Services with Unisys Communications Solution

Advanced messaging platform helps to define new company

Blue Bell, PA: April 11, 2007. Unisys Corporation (NYSE: UIS) today announced that it has successfully implemented a next-generation, value-added messaging platform for EMBARQ, a leading provider of communications services to consumers in 18 states.

EMBARQ, created from the spin-off of the former local communications division of Sprint and launched as a public company in May 2006, used Unisys Next Generation Messaging Service (NGMS) as the basis of an innovative suite of enhanced messaging services. NGMS provides rich, converged messaging services including unified communications, voice messaging, family mailboxes, and fixed-mobile converged mailboxes. The next generation services capability of NGMS has allowed EMBARQ to offer enhanced services such as the EMBARQTM Together PlanSM with integrated voicemail, allowing customers to retrieve messages from either their wireless or home phone device.

"The Unisys solution suite is enabling us to give our subscribers a seamless approach to converged communications messaging," said Harry Campbell, president of EMBARQ Consumer Markets. "Unisys delivered a mission-critical application on-time, on-budget, and did whatever was necessary to shorten the timelines and meet our objectives to launch the NGMS as we launched a whole new company with millions of customers."

Unisys has integrated a next generation, service-oriented architecture (SOA) for EMBARQ to provide converged communications messaging solutions to EMBARQ consumers in 18 states. These consumer services, developed in conjunction with Data Connection Limited (DCL), can be used from mobile, residence, and office phones as well as personal computers. EMBARQ has increased its voicemail sales from approximately 3,000 a month to over 100,000.

"As the competitive communication market converges in the consumer's home, office and on the move, it is increasingly important for EMBARQ to be able to build new services quickly," said Glenn James, president, Global Communications, Unisys. "The consumer expects that communication services become seamless regardless of what location and device they use, so Unisys is providing the services and framework that help unify these technologies. This effort illustrates how agile technology solutions can connect business strategy, technology devices and consumer need."

EMBARQ has integrated all new subscribers to the advanced messaging service and has begun the migration of its existing subscribers to the new platform. Unisys will continue its role as a valued technology provider to EMBARQ in 2007 by working with the company to enhance its offerings through the implementation of advanced calling features and further improvements to the messaging service.
