Hi Matthew,

Yes, CUVA is intended to be used with Cisco IP Telephony. Here is an overview;

Overview of Cisco Unified Video Advantage

Cisco Unified Video Advantage brings video telephony functionality to the all video-enabled Cisco Unified IP Phones including Cisco IP Communicator. The Cisco Unified Video Advantage software coupled with the Cisco VT Camera (a USB camera) allows a personal computer (PC) connected to a Cisco Unified IP Phone to add video to phone calls without requiring any extra button-pushing or mouse-clicking. When registered to Cisco Unified CallManager, the Cisco Unified Video Advantage-enabled Cisco Unified IP Phone has the features and functionality of a full-featured IP videophone. Call features like call forward, transfer, conference, hold, and mute are available with video - and are all initiated through the Cisco IP Communicator or Cisco Unified IP Phone. Cisco Unified Video Advantage is intended for desktop-to-desktop IP video telephony environments, not as a general purpose video conferencing solution for use in conference rooms.
