Avaya one-X Desktop

Avaya one-X™ Desktop Edition is a PC based phone application that transforms Windows-based computers into intelligent SIP-based collaboration endpoints. Users are able to make, receive and handle voice calls, send instant messages to one another and track each others' presence using an intuitive graphical user interface.
