© 2008 Cisco Systems, Inc. All rights reserved.CIPT1 v6.0—5-13 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.

© 2008 Cisco Systems, Inc. All rights reserved.CIPT1 v6.0—5-14 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).

© 2008 Cisco Systems, Inc. All rights reserved.CIPT1 v6.0—5-15 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.

© 2008 Cisco Systems, Inc. All rights reserved.CIPT1 v6.0—5-16 Step 3: Required Phone Configuration Settings for Video Support PC Port (enabled by default): Must be enabled. Device > Phone Video Capabilities (disabled by default): Must be enabled.
