Actually it's more of a applet that allows you to click on *any phone number* that it sees in a email signature, webpage, etc and it would call it via the handset ?
My blackberry has this *feature*. It's pretty slick in that if I am reading and email, and there is a phone number in the email, the unit will automatically highlight it and I just *click the button* to call that #.
Citrix has this app for both the Nortel and Avaya system, but it appears that it's not for the IPO Platform.
