Cisco Unified CallManager Group Configuration


A Cisco Unified CallManager Group specifies a prioritized list of up to three Cisco Unified CallManagers. The first Cisco Unified CallManager in the list serves as the primary Cisco Unified CallManager for that group, and the other members of the group serve as secondary and tertiary (backup) Cisco Unified CallManagers.

Each device pool has one Cisco Unified CallManager Group assigned to it. When a device registers, it attempts to connect to the primary (first) Cisco Unified CallManager in the group that is assigned to its device pool. If the primary Cisco Unified CallManager is not available, the device tries to connect to the next Cisco Unified CallManager that is listed in the group, and so on.

Cisco Unified CallManager Groups provide important features for your system:

Redundancy—This feature enables you to designate a primary and backup Cisco Unified CallManagers for each group.

Call processing load balancing—This feature enables you to distribute the control of devices across multiple Cisco Unified CallManagers.

For most systems, you need to have multiple groups, and you need to assign a single Cisco Unified CallManager to multiple groups to achieve better load distribution and redundancy.

Use the following topics to add, update, or delete a Cisco Unified CallManager group:

Configuring a Cisco Unified CallManager Group

This section describes how to add, copy, or update a Cisco Unified CallManager group.

Before You Begin

Before configuring a Cisco Unified CallManager group, you must configure the Cisco Unified CallManagers that you want to assign as members of that group. See the "Updating a Cisco Unified CallManager" section for more information.

Procedure


Step 1 Choose System > Cisco Unified CallManager Group.

The Find and List Cisco Unified CallManager Groups displays.

Step 2 Perform one of the following tasks:

To copy an existing Cisco Unified CallManager Group, locate the appropriate Cisco Unified CallManager Group as described in the "Finding a Cisco Unified CallManager Group" section, choose the Cisco Unified CallManager Group that you want to copy, click Copy, and continue with Step 3.

To add a new Cisco Unified CallManager Group, click Add New button, and continue with Step 3.

To update an existing Cisco Unified CallManager Group, locate the appropriate Cisco Unified CallManager Group as described in the "Finding a Cisco Unified CallManager Group" section, and continue with Step 3.

Step 3 Enter the appropriate settings as described in Table 4-1.

Step 4 Click the Save icon that displays in the tool bar in the upper, left corner of the window (or click the Save button that displays at the bottom of the window) to save the Cisco Unified CallManager Group configuration in the database.

After you have configured the Cisco Unified CallManager Group, you can use it to configure device pools. Devices obtain their Cisco Unified CallManager Group list setting from the device pool to which they are assigned.


Additional Information

Name

Enter the name of the new group.

Auto-registration Cisco Unified CallManager Group

Check the Auto-registration Cisco Unified CallManager Group check box if you want this Cisco Unified CallManager group to be the default Cisco Unified CallManager group when auto-registration is enabled.

Leave this check box unchecked if you do not want devices to auto-register with this Cisco Unified CallManager group.

Note Each Cisco Unified CallManager cluster can have only one default auto-registration group. If you choose a different Cisco Unified CallManager group as the default auto-registration group, the previously chosen auto-registration group no longer serves as the default for the cluster.

Cisco Unified CallManager Group Members

Deleting a Cisco Unified CallManager Group

This section describes how to delete a Cisco Unified CallManager Group from the database.

Before You Begin


Note You cannot delete a Cisco Unified CallManager group if it is assigned to any device pools or MGCP gateways or if it is the current Auto-registration Cisco Unified CallManager Group for the cluster.


To find out which devices are using the Cisco Unified CallManager group, choose Dependency Records from the Related Links drop-down list box on the Cisco Unified CallManager Group Configuration window and click Go.

If the dependency records feature is not enabled for the system, the dependency records summary window displays a message that shows the action that you can take to enable the dependency records; the message also displays information about high CPU consumption that is related to the dependency records feature. For more information about dependency records, see the "Accessing Dependency Records" section on page A-2.

If you attempt to delete a Cisco Unified CallManager group that is in use, an error message displays. Before deleting a Cisco Unified CallManager group that is currently in use, you must perform some or all of the following tasks:

Assign a different Cisco Unified CallManager group to the device pools or MGCP gateways that currently use this Cisco Unified CallManager group. See the "Configuring a Device Pool" section.

Create or choose a different Cisco Unified CallManager group to be the Auto-registration Cisco Unified CallManager Group.

Procedure
