9 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Configuring Cisco Unified CallManager for Video To enable video in your existing voice network, start with Cisco Unified CallManager configuration.

10 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Cisco Unified CallManager Considerations When Enabling Video Update locations and regions configuration. Reconsider call routing. Configure separation of MRGLin connection with SCCP MCUs only. Reconsider DSCP values.

11 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Configuring Video Bandwidth Properties in Cisco Unified CallManager When enabling video, update regions and locations configuration by setting the video bandwidth parameters.

12 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Call-Routing Considerations Existing dial plan and call-routing features are used: Route or hunt lists or AAR groups can try different paths also for video calls. Retry Video Call as Audio option has a higher preference than AAR.

13 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v QoS Considerations for Video Calls Enabling video in the network requires updates of your QoS policy this can include new DSCP values. Set DSCP values according to your updated QoS policy under Cisco Unified CallManager > Service Parameters. Audio streams in audio-only calls default to EF. Video streams and associated audio streams in video calls default to AF41.

14 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Configuring Cisco IP Phones for Cisco Unified Video Advantage Configure Cisco IP phones in Cisco Unified CallManager configuration to support Cisco Unified Video Advantage.

15 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v IP Phone Video Configuration Checklist Verify that your phone loads support videosupported phones include Cisco Unified IP Phone 7940, 7941, 7960, 7961, 7970, 7971, and Cisco IP Communicator. Enable the PC port. Enable video support. Check or uncheck Retry Video Call as Audio. Verify the IP phone configuration.

16 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Verify the Phone Loads IP phone load 6.4(4) or higher for 7940 and 7941 IP phone load 6.0(4) or higher for 7960 and 7961 IP phone load 6.0(2) or higher for 7970 and 7971 Cisco Unified CallManager Release 5.0 ships with IP phone load 8.0(1) or higher.

17 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Required Phone Configuration Settings for Video Support PC port: –Enabled by default –Must be enabled for Cisco Unified Video Advantage Video capabilities: –Disabled by default –Enable to allow Cisco Unified Video Advantage to associate with phone Both settings found at the Phone Configuration page

18 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v Enabling Retry Video Call as Audio A video-enabled IP phone can be configured to retry video calls as audio calls if the video call cannot be set up. This parameter is enabled by default. This parameter is configured at the Phone Configuration page.

19 © 2006 Cisco Systems, Inc. All rights reserved.CIPT2 v 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.
