Interesting -- I wonder if they'll expand it to other "smart tag" content types.
Citrix has teamed up with Cisco to let users easily call phone numbers that appear in any application they're working on.
With Citrix Presentation Server, enterprises can run applications centrally and have employees simply work with an image of the application on each client device. Through integration with Cisco's CallManager VOIP (voice over Internet Protocol) system, the companies have been offering a click-to-call feature for a limited number of applications. After rolling a mouse over any phone number that appears in an application, users see a pop-up menu and can click on the option "Call" to dial the number on a Cisco phone.
