3. Cisco Unified Video Advantage Overview

4. Cisco Unified Video Advantage Overview 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.

5. Cisco Unified VideoAdvantage Components Unified CM: Release 4.0(1) with Service Release 2 or later Cisco Unified IP Phones794[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

6. 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.

7. Cisco Unified Video AdvantageSupportedMultimedia Standards H.263 and H.264 video codec (from 50 kbps to 1.5 Mbps) Cisco wideband video codecs (7 Mbps) Supports video formats up to 30 fps: CIF (352 x 288, 230 x 240) QCIF (176 x 144, 160 x 120)

8. Cisco Unified Video Advantage Communication Flows

9. 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)

10. How Calls Work with Cisco Unified Video Advantage Phone VLAN PC VLAN 802.1Q 1 Cisco Discovery Protocol Inter-VLAN Routing “Cisco Audio Session Tunnel: Association” 2 Signaling Proxy for Video “SCCP: Call Signaling (Video and Voice)” 3 Inter-VLAN Routing “Cisco Audio Session Tunnel : Call Signaling (Video Only)” 4 Audio Packets Video Packets

11. 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. Video Call Speed at 384 kbps with G.711 320 kbps 64 kbps Video Audio Video Call Speed at 384 kbps with G.729 376 kbps 8 kbps

12. Cisco Unified Communications Manager Cisco Unified Video Advantage Configuration

13. Unified CM Cisco Unified Video Advantage Configuration Procedure Configure regions with the maximum audio codec and video call speed to be used per video call. Configure the maximum allowed bandwidth used by video calls between different locations. Configure the IP phone in Unified CM to support Cisco Unified Video Advantage. Verify Cisco Unified Video Advantage support on the IP phone.

14. Step 1: Setting the Maximum Audio Codec and Video Call Speed Allowed Per Video Call System > Region Sets audio codec with the highest allowed codec bit rate. Applies to audio channels of audio and video calls. Sets the maximum video call speed. Includes audio and video channel).

15. 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. Applies to audio and video channels of video calls.

16. Step 3: Required Phone ConfigurationSettings for Video Support Device > Phone PC Port (enabled by default): Must be enabled. Video Capabilities (disabled by default): Must be enabled.

17. 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.

18. Cisco Unified Video Advantage Installation

19. Cisco Unified Video Advantage Installation Procedure Consider hardware requirements Consider software requirements Install Cisco Unified Video Advantage software and hardware

20. 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

21. 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

22. 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

23. Step 3b: Cisco Unified Video Advantage Installation 1 Install Cisco Unified Video Advantage with Installation Wizard. 3 2 4 Camera will be found automatically. Installation is complete. Plug in camera.

24. Cisco Unified Video Advantage Verification Tools

25. 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 IP Phone, Connection Not Successful Camera Associated with Cisco IP Communicator, Connection Successful

26. 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.

27. 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.

28. 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.
