FORT LAUDERDALE, Fla.–(BUSINESS WIRE)–Oct. 31, 2005–Citrix Systems, Inc. (Nasdaq: CTXS), the global leader in access infrastructure solutions, today announced the availability of its new Smart Agent technology with release 6.0 of the Citrix Application Gateway(TM). The Citrix Application Gateway, which provides converged business applications for delivery to screens and speakers of IP telephones, is extending its footprint with Smart Agent to provide productivity applications to users’ personal computers in addition to IP telephones. The first Citrix application to use Smart Agent technology is Click-to-Call which enables telephone users to dial their desk telephone by simply clicking on linked telephone numbers in e-mail or Web applications, delivering the best user experience in computer-telephone interaction.

Over the past decade, countless efforts have been made to develop a straightforward way to integrate computers and telephones. While this interaction has been successful in customer contact centers, there has been limited success with knowledge workers. User experience with these applications was one of the limiting factors driving slowness in adoption, but the primary reason why this effort was unsuccessful lay in the complexity of systems integration. Until now, an IT administrator needed to install a Telephony Application Program Interface (TAPI) service provider on each personal computer and update this desktop software with each and every change to the PBX software or application software. Citrix’s Smart Agent technology provides the simplest, most intuitive access experience for both end-users and IT administrators by using a small Web distributed, auto-updating client that alleviates complex deployment and upgrade issues.

How Smart Agent with Click-to-Call Works

— Users download a small, auto-updating client from an internal
website and logs in using their regular Windows credentials.

— Telephone numbers in e-mail and Web applications are turned to
click-able hot links.

— Users can now click on a telephone number link and their phone
automatically dials that number.

“Many organizations are still laying the foundation of their VoIP networks, and have yet to deploy advanced VoIP applications,” said Matthias Machowinski, directing analyst at Infonetics Research. “However, organizations will eventually want to take their VoIP deployment to the next level. Citrix’s suite of VoIP applications gives them a choice in application vendors, while interoperability - usually a big concern among buyers - won’t be an issue because Citrix already has relationships with the major IP PBX vendors.”

“We’ve all experienced frustrations with telephone numbers embedded everywhere - in our cell phones, on websites and in Microsoft Outlook. This inefficient process of flipping back and forth between your PC and telephone often leads to misdialed numbers and users relying on their cell phones more than their desk phones,” said Murli Thirumale, group vice president and general manager, Gateways Group, Citrix. “Smart Agent simplifies the user interaction with telephony-enabled applications, but also the deployment model that has historically stymied the success of these types of applications.”

Smart Agent with Click-to-Call supports any Web application that can be accessed with Microsoft Internet Explorer including Sales Force Automation (SFA), Customer Relationship Management (CRM), Enterprise Resource Planning (ERP), and other applications that are used to manage customer, partner, or employee data. Initial e-mail application support includes Microsoft Outlook and Outlook Express as well as Eudora and any web-based e-mail system.
