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:

Finding a Cisco Unified CallManager Group

Because you might have several Cisco Unified CallManager groups in your network, Cisco Unified CallManager Administration lets you locate specific Cisco Unified CallManager groups on the basis of specific criteria. Use the following procedure to locate Cisco Unified CallManager groups.


Note During your work in a browser session, Cisco Unified CallManager Administration retains your Cisco Unified CallManager group search preferences. If you navigate to other menu items and return to this menu item, Cisco Unified CallManager Administration retains your Cisco Unified CallManager group search preferences until you modify your search or close the browser.


Procedure


Step 1 Choose System > Cisco Unified CallManager Group.

The Find and List Cisco Unified CallManager Groups window displays. Use the drop-down list box to search for a Cisco Unified CallManager Group.

Step 2 From the Find Cisco Unified CallManager Groups where drop-down list box, choose one of the following criteria:

begins with

contains

ends with

is exactly

is not empty

is empty

Step 3 Specify the appropriate search text, if applicable, and click Find. You can also specify how many items per page to display.


Tip To find all Cisco Unified CallManager groups that are registered in the database, click Find without entering any search text.


A list of discovered Cisco Unified CallManager groups displays by

Cisco Unified CallManager Group icon

Cisco Unified CallManager Group name

Auto-registration Default


Note You can delete multiple Cisco Unified CallManager groups from the Find and List Cisco Unified CallManager Groups window by checking the check boxes next to the appropriate Cisco Unified CallManager groups and clicking Delete Selected. You can delete all Cisco Unified CallManager groups in the window by checking the check box in the Matching records title bar and clicking Delete Selected.


Step 4 From the list of records, click the Cisco Unified CallManager Group icon or name that matches your search criteria.

The window displays the Cisco Unified CallManager group that you choose.

This section describes how to configure a new Cisco Unified CallManager group. You can also create a new Cisco Unified CallManager group by copying an existing one. See the "Copying a Cisco Unified CallManager Group" section for more information.

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 "Adding a Cisco Unified CallManager" section on page 3-4 for more information.

Procedure


Step 1 Choose System > Cisco Unified CallManager Group.

Step 2 In the upper, right corner of the window, click the Add a New Cisco Unified CallManager Group link.

The Cisco Unified CallManager Group Configuration window displays.

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

Step 4 Click Insert to save the Cisco Unified CallManager group 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.

Updating a Cisco Unified CallManager Group

This section describes how to update an existing Cisco Unified CallManager group.

Procedure


Step 1 Find the Cisco Unified CallManager group by using the procedure in the "Finding a Cisco Unified CallManager Group" section.

Step 2 Click the Cisco Unified CallManager group that you want to update.

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


Note To designate a group as the default Auto-registration Cisco Unified CallManager Group, check the Auto-registration Cisco Unified CallManager Group check box.

If the currently selected group is the default group for auto-registration, you cannot change it by unchecking the Auto-registration Cisco Unified CallManager Group check box. You must choose a different default auto-registration group. When you do so, the Cisco Unified CallManager automatically changes the currently selected default auto-registration group.


Step 4 Click Update to save the changes in the database.

You must reset the devices that use the updated Cisco Unified CallManager group to apply the changes. To reset all the devices that use this Cisco Unified CallManager group, click Reset Devices.


Tip For your convenience in resetting devices, the Reset Devices button resets all devices in the device pool that uses this Cisco Unified CallManager group.



Caution Resetting devices can cause calls in progress to drop.

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

Before You Begin

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, click the Dependency Records link from the Cisco Unified CallManager Group Configuration window. If the dependency records are not enabled for the system, the dependency records summary window displays a message. For more information about dependency records, see the "Accessing Dependency Records" section on page A-3. If you try 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 are currently using this Cisco Unified CallManager group. See the "Updating a Device Pool" section on page 8-5.

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

Procedure


Step 1 Find the Cisco Unified CallManager group by using the procedure in the "Finding a Cisco Unified CallManager Group" section.

Step 2 From the list of matching records, choose the group that you want to delete.

Step 3 Click Delete.

Step 4 When asked to confirm the delete operation, click either OK to delete or Cancel to cancel the delete operation.
