FORT LAUDERDALE, Fla. — 11/13/2006 — Citrix Systems, Inc. (Nasdaq: CTXS), the global leader in application delivery infrastructure, today announced that Technology Marketing Corporation’s (TMC®) INTERNET TELEPHONY® magazine (http://www.itmag.com) has named Citrix Application Gateway™ with the Citrix® Voice Office application suite as a recipient of a 2006 INTERNET TELEPHONY Excellence Award. INTERNET TELEPHONY magazine has been a VoIP Authority since 1998™.

“We are honored to receive recognition for the innovative IP Communications applications being delivered through the Citrix Application Gateway,” said Gordon Payne, vice president of marketing, Advanced Solutions Group, Citrix. “This is especially significant as it is based on the experience of one of our customers, Credit Valley Hospital, who is leveraging Citrix Voice Office applications to speed communications and eliminate the cost of a separate overhead paging system. They are a great example of how organizations are utilizing Citrix application delivery solutions to gain further benefit from their IP telephony investment.”

The Citrix Application Gateway is used by organizations such as Credit Valley Hospital to deliver IP Communications applications to IP telephones and users’ PCs. Citrix Voice Office is a suite of packaged IP telephony applications, including Click-to-Call, Zone Paging, Visual Voicemail, Broadcast Alerts, and Express Directory. Citrix Click-to-Call enables users to dial their desk telephone by simply clicking on any telephone number in any application, whether it is deployed on Citrix Presentation Server™ or on the user’s PC or laptop. These applications increase employee productivity, reduce user training, and provide new ways to communicate that were previously not available with traditional telephone systems.
