Video Call Traffic Class Definition

Explanation.

In Cisco Unified Communications Manager (Unified CM), Enhanced Location Call Admission Control (CAC) allows administrators to manage bandwidth consumption and prevent overloading of network resources. To properly configure Enhanced Location CAC for video call traffic, the Video Call Traffic Class must be defined.

The Video Call Traffic Class is a configurable parameter in Unified CM that is used to determine the amount of bandwidth required for video calls. This parameter is set on a per-device or per-Device Pool basis, and can be configured in one of the following ways:

A. On each device's configuration page: This option allows administrators to define the Video Call Traffic Class for individual devices. To configure this setting, navigate to the device's configuration page in Unified CM, and select the appropriate value for the Video Call Traffic Class parameter.

B. On Device Profile page: This option allows administrators to define the Video Call Traffic Class for a group of devices through the use of Device Profiles. Device Profiles are templates that can be applied to multiple devices to simplify configuration management. To configure this setting, navigate to the Device Profile configuration page in Unified CM, and select the appropriate value for the Video Call Traffic Class parameter.

C. On SIP Profile configuration page: This option is used for devices that utilize SIP (Session Initiation Protocol) for call signaling. SIP Profiles are used to define settings for SIP devices, including the Video Call Traffic Class. To configure this setting, navigate to the SIP Profile configuration page in Unified CM, and select the appropriate value for the Video Call Traffic Class parameter.

D. On Location configuration page: This option allows administrators to define the Video Call Traffic Class for a specific Location in Unified CM. Locations are used to define the physical location of devices, and can be used to restrict the amount of bandwidth available for calls originating from or terminating at that Location. To configure this setting, navigate to the Location configuration page in Unified CM, and select the appropriate value for the Video Call Traffic Class parameter.

E. On each device or Device Pool's configuration page: This option allows administrators to define the Video Call Traffic Class for individual devices or groups of devices. To configure this setting, navigate to the appropriate device or Device Pool configuration page in Unified CM, and select the appropriate value for the Video Call Traffic Class parameter.

In summary, the Video Call Traffic Class can be configured in multiple ways in Cisco Unified CM, depending on the specific requirements of the network and the devices being used. The most appropriate method will depend on the specific use case and the level of granularity required for bandwidth management.
