MCI And Microsoft Expand Strategic Relationship; Launch New Collaboration Capabilities In Asia-Pacific

Feature-Rich Web Conferencing Makes Virtual Conferences More like In Person Meetings

HONG KONG, China, November 14, 2005 - MCI, Inc. (Nasdaq: MCIP) today announced it is working with Microsoft to offer newly enhanced IP-based collaboration services for businesses across Asia Pacific. With the latest version of MCI Net Conferencing Powered by Microsoft Live Meeting, launched in July in the United States and Europe, Asia Pacific companies can now conduct Web conferences that feel more like virtual meetings.

“The powerful combination of MCI’s advanced network solutions with Microsoft’s leading software and application technologies is fueling the next generation of collaboration services,” said Nancy Gofus, senior vice president of MCI IP Services. “MCI Net Conferencing powered by Microsoft Live Meeting is a terrific example of how the two companies continue to work together and transform the way business gets done around the world.”

As the leading provider of Microsoft Office Live Meeting, an online collaboration and Web conferencing service, MCI has worked closely with Microsoft to develop next-generation conferencing capabilities. MCI Net Conferencing now offers the 2005 release of Microsoft Office Live Meeting, integrating Web and audio conferencing capabilities, so that users can better manage their audio needs in a seamless Web-based environment. By combining the two companies’ capabilities into a seamless user experience, MCI and Microsoft are enabling business customers to take advantage of multimedia, interactive real-time communications in a rich collaborative setting.

The latest generation of Microsoft Live Meeting provides meeting presenters with more control over online collaborations by focusing on content versus delivery and encouraging more interaction between presenter and participants. Using a new improved control console more closely integrated with the Microsoft Office suite, presenters can more simply change views between documents without opening a new window, increase slide building and animation effects and drop and drag content into a slide show. In addition, participants can more simply ask questions at any time during a meeting using new sidebar Q&A features.

MCI, named by Frost and Sullivan in 2004 as Asia Pacific’s “Most Comprehensive Service Provider,” continues to widen its portfolio of voice, data and IP products in Hong Kong with this latest version of MCI Net Conferencing powered by Microsoft Live Meeting. Businesses across the globe can now benefit from an integrated communications solution that allows for voice, video and document sharing capabilities. With a simple click of the mouse, MCI customers can quickly connect to coworkers, partners and customers via email, phone, Web conferencing or instant messaging, utilizing a secure portal and IP transport.

“Through our partnership with MCI, we are advancing Microsoft’s strategy of helping information workers collaborate and communicate in Hong Kong, Helsinki or Houston, said Taylor Collyer, senior director of Product Management, Real-Time Collaboration Business Unit, Microsoft. ”As a result businesses can make more informed and quicker decisions that produce desired results"
