/mcpProcedure Step 1 From Cisco Unified CM Administration, choose System > Service Parameters. Step 2 From the Server drop-down list, choose the server where you want to configure the parameters. Step 3 From the Service drop-down list, choose the Cisco CallManager (Active) service. If the service does not display as active, ensure that the service is activated in Cisco Unified Serviceability. Step 4 To configure a Video Promotion policy that promotes desktop video endpoints to immersive video endpoints, set the Use Video BandwidthPool for Immersive Video Calls parameter to False and set the Video Call QoS Marking Policy parameter to Promote to Immersive. Step 5 To configure other parameters, scroll to the appropriate area of the Service Parameter Configuration window and update the parameter values. See Flexible DSCP Marking and Video Promotion Service Parameters, on page 774 for information about the service parameters and their configuration options. Step 6 Click Save. Flexible DSCP Marking and Video Promotion Service Parameters For more information about the service parameters, click the parameter name or click the question mark (?) icon that displays in the Service Parameter Configuration window. Note Table 80: Flexible DSCP Marking and Video Promotion Service Parameters Description Parameter This section of service parameters includes clusterwide DSCP values for a wide range of audio and video call types, including DSCP for audio calls, video calls, the audio portion of a video call, TelePresence calls, and the audio portion of a TelePresence call. It is highly recommended that you keep these parameters set to the default value unless a Cisco support engineer instructs otherwise. Clusterwide Parameters (System - QoS) Clusterwide Parameters (Call Admission Control) This parameter allows you to configure a Promote to Immersive policy that reconciles bandwidth allocation inconsistencies between a desktop video endpoint and a Cisco TelePresence immersive video endpoint in favor of the immersive endpoint. When promotion is performed, the audio and video bandwidth are reserved from the immersive bandwidth pool allocation. The policy of Promote to Immersive takes effect only for calls between an immersive video device and a desktop video device that supports flexible DSCP marking.
