Cisco Unified Video Advantage adds video capabilities to an IP phone.

It uses software on a PC connected to an IP phone.

The PC has a video camera connected.


Cisco Unified Video Advantage Components

Unified CM:

– Release 4.0(1) with Service Release 2 or later

Cisco Unified IP Phones 794[0125], 796[0125], or 797[015] (or alternatively Cisco IP Communicator 2.0 or later)

PC with video camera and software:

– Cisco Unified Video Advantage camera connected via USB

– Cisco Unified Video Advantage software


Cisco Unified Video Advantage Component Interaction

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.

Cisco Unified Video Advantage Communication Flows


Protocols Used by Cisco Unified Video Advantage

Cisco Discovery Protocol: Discovery between IP phone and PC

Cisco Audio Session Tunnel: Association and signaling between IP phone and Cisco Unified Video Advantage software

SCCP: Signaling between IP phone and Unified CM

RTP: Media transport (video to Cisco Unified Video Advantage, audio to phone)

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.

Cisco Unified Communications Manager Cisco Unified Video Advantage Configuration


Unified CM Cisco Unified Video Advantage Configuration Procedure

1. Configure regions with the maximum audio codec and video call speed to be used per video call.

2. Configure the maximum allowed bandwidth used by video calls between different locations.

3. Configure the IP phone in Unified CM to support Cisco Unified Video Advantage.

4. Verify Cisco Unified Video Advantage support on the IP phone.


Step 1: Setting the Maximum Audio Codec and Video Call Speed Allowed Per Video Call

Sets audio codec with the highest allowed codec bit rate.

Applies to audio channels of audio and video calls.

System > Region

Sets the maximum video call speed.

Includes audio and video channel).


Step 2: Setting the Maximum Allowed Bandwidth Used by Video Calls for Locations

Sets the maximum audio bandwidth for a location.

Applies to audio-only calls only, not to audio channel of a video call.

System > Location

Sets the maximum video bandwidth for a location.

Applies to audio and video channels of video calls.


Step 3: Required Phone ConfigurationSettings for Video Support

PC Port (enabled by default): Must be enabled.

Device > Phone

Video Capabilities (disabled by default): Must be

enabled.


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.


Cisco Unified Video Advantage Installation


Cisco Unified Video Advantage Installation Procedure

1. Consider hardware requirements

2. Consider software requirements

3. Install Cisco Unified Video Advantage software and hardware


Step 1: Cisco Unified Video Advantage Hardware Requirements

PC:

– At least 1.9 GHz CPU

– At least 512 MB memory

– At least 100 MB free disk space

– At least one USB port

– Connected to a Cisco Unified IP Phone 794[0125], 796[0125], or 797[015] or colocated with Cisco IP Communicator

Cisco VT Camera:

– Connected to a USB port of the PC


Step 2: Cisco Unified Video Advantage Software Requirements

Operating system:

– MS Windows 2000 with Service Pack 4 or later

– MS Windows XP with Service Pack 2 or later

Cisco Unified Video Advantage software

– Downloaded from Cisco.com


Step 3a: Cisco Unified Video Advantage Installation – Preparation Checklist

Ensure that the Cisco IP phone or Cisco IP Communicator is registered.

Ensure that the Cisco IP phone or Cisco IP Communicator is video-enabled.

Ensure that the PC is connected to the IP phone and verify IP connectivity between IP phone and PC (not needed with Cisco IP Communicator):

– Check reachability using ping

– Ensure that Cisco Audio Session Tunnel protocol is not filtered between PC and IP phone


Step 3b: Cisco Unified Video Advantage Installation

Install Cisco Unified Video Advantage with Installation

Wizard.

Installation is complete.

Cisco Unified Video Advantage Verification Tools


Cisco Unified Video Advantage Verification of IP Phone Association

After starting the Cisco Unified Video Advantage software, verify the status of the connection to the IP phone or Cisco IP Communicator.

Camera Associated with Cisco IP Communicator, Connection Successful

Camera Associated with IP Phone, Connection

Not Successful


Cisco Unified Video Advantage Verification of Camera

After verifying the camera connection status, run a video check, and you should see the camera input in both windows, the remote and the local view.


Active Call Verification with the Diagnostic Tool

You can open a call diagnostic window by right-double-clicking the Cisco Unified Video Advantage application window.

The diagnostic window allows you to monitor Cisco Discovery Protocol packets, Cisco Audio Session Tunnel packets, and active call statistics.


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.
