Installed
 Cisco Unified Video Advantage software on PC associates with IP
phone.
 IP phone registers as a video-capable phone.
 If both IP phones involved in a call are video-capable, a video call
is set up: audio is on the IP phone, video is on the PC.
 Mid-call video feature allows video stream to be brought up during
the call if video capabilities are added mid-call.

Video Call Bandwidth for Audio and
Video Channels
 Video call includes two channels:
– Audio channel
– Video channel
 The bit rate available for the video channel depends on the
negotiated audio codec and the overall video call speed.

speed.
Includes audio and video channel).
CIPT1 v6.0—5-14
Step 2: Setting the Maximum Allowed
Bandwidth Used by Video Calls for Locations
System > Location
Sets the maximum audio
bandwidth for a location.
Applies to audio-only calls only, not
to audio channel of a video call.
Sets the maximum video
bandwidth for a location.

Step 4: Verification of Phone
Configuration
 A video-enabled IP phone
shows a small camera on its
screen.
 The symbol is visible after the
phone is configured to
support video calls:
– It does not indicate that
Cisco Unified Video
Advantage has been
associated with the
IP phone.

Summary
 Cisco Unified Video Advantage adds video capabilites to Cisco IP
phones by using software and camera on a PC attached to the IP
phone.
 Cisco Unified Video Advantage discovers the IP phone by
listening to Cisco Discovery Protocol messages and uses the
Cisco Audio Session Tunnel protocol to associate with the IP
phone and to send and receive signaling messages.
 In order to enable Cisco Unified Video Advantage, IP phones
have to be video-enabled and regions and locations must be
configured to permit video calls.
 Before installing Cisco Unified Video Advantage on the PC, verify
hardware and software requirements.
 Cisco Unified Video Advantage includes tools to verify the
association with the IP phone, check the camera, and perform
diagnostics.
