LiteScape Technologies to Deliver Unified IP Communications Applications Through WebEx Connect

REDWOOD SHORES and SANTA CLARA, Calif., November 16, 2006 LiteScape Technologies (www.litescape.com), a leader in unified communication applications, and WebEx (Nasdaq: WEBX), the leading provider of collaborative software-as-a-service (SaaS) applications, today announced the LiteScape OnCast solution will be available through WebEx Connect. LiteScape enhances the value of IP-based networks by facilitating collaboration with an IP Telephony broadcast solution that interacts with desktop directories and calendars to provide quick and simple access to network directories across multiple locations and clusters. Together with WebEx Connect users will experience unprecedented access and control over both their contacts and online collaborative sessions.

LiteScapes unified communication applications permit organizations to efficiently deliver multi-modal messages for emergency, security and general announcements from a variety of devices and a collection of IP end points. OnCast will enable WebEx Connect users to search all network directories, and when used with Microsoft Outlook, send and accept invitations from IP phones to organize and join WebEx collaborative sessions.

"Seamless, unified communications across multiple technologies is a critical success factor for business today," said Rod Hamlin, executive vice president of sales and marketing for LiteScape. "The combination of LiteScape applications and WebEx collaboration solutions will truly deliver improved productivity with IP integration. The ability to search and dial, search and broadcast, and search and collaborate will increase productivity and provide a tangible return for our customer base."

LiteScape OnCast is one of the many applications users will be able to access through their personal WebEx Connect workspace and the WebEx Connect grid of partner applications. WebEx Connect is the first application platform specifically designed for on-demand collaboration and third party application integration. WebEx Connect allows users to integrate data from multiple applications and create a collaborative workspace custom designed for their particular workflow and business process. By leveraging open Web 2.0 protocols and collaborative WebEx MediaTone APIs, WebEx Connect makes it easy for developers to adapt on-demand, desktop and enterprise applications to the platform or create new composite, "mashup" applications.

"By integrating WebEx and IP PBXs with partners like LiteScape, we provide a single, unified solution to improve the collaboration that drives todays business," said David Knight, vice president, WebEx Connect. "By harnessing the power of WebEx Connect and the IP-telephony revolution, our customers will be able to instantly connect and collaborate from within customized, business process specific workspaces."
