Call Manager Groups

Full HTML Help

Overview

A Call Manager Group (Cisco UCM group), contains a list of up to three UCM servers (users). These servers are prioritized. The server marked with the lowest number (zero) serves as the primary UCM user for that group, and the other members of the group serve as secondary and tertiary (backup) UCMs.

Each device pool has one UCM group that is assigned to it. When a device registers, it attempts to connect to the primary UCM user in the group assigned to its device pool. If the primary UCM is unavailable, the device tries to connect to the next UCM listed in the group, and so on.

A single UCM user is usually assigned as primary for one UCM group, and as secondary / tertiary (if applicable) on other UCM groups.

The table describes the value of UCM groups for your system:

For systems with a UCM that includes multiple servers (users), you are likely to achieve better load distribution and redundancy.

Manage Call Manager Groups

This procedure adds a new UCM group, and edits and deletes an existing UCM group.

Prerequisites:

• Configure all UCM servers (users) that you want to assign as members of the Call Manager group.

Perform these steps:

1. Log in to the Admin Portal as a Provider, Reseller, or Customer administrator.

   Note

   For Shared Architecture deployment, ensure you sign in only as either Provider or Reseller admin as only these admins can add UCMs.

2. If you are adding a new instance, ensure the hierarchy path is set to the target node for the new instance.

3. Go to Call Manager Groups.

4. Choose an option:

   • To add a new UCM group, click the Plus icon (+), then go to step 5.
   • To edit an existing UCM group, click on the relevant option in the list to open its settings, then go to step 5.

5. Configure the UCM group:

   Field	Description
   Name (Mandatory)	Fill out the UCM group name.
   Auto-registration Cisco Unified Communications Manager Group	Select this checkbox if you want this UCM group to be the default UCM group when auto-registration is enabled. Leave unchecked (disabled) if you don't want devices to auto-register with this UCM group. Tip Each UCM cluster can have only one default auto-registration group. If you choose a different UCM group as the default auto-registration group, that is, you select the Auto-registration Cisco Unified Unified Communications Manager Group* checkbox for a different UCM group, the previously chosen auto-registration group no longer serves as the default for the cluster; the Auto-registration Cisco Unified Communications Manager* checkbox displays for the previously chosen group (the original default), and the checkbox gets disabled for the group that now serves as the default.
   Unified CM Group Items (Mandatory)	Click the Plus icon (+) to add a UCM to the group. Repeat to add multiple UCM's to the group. You can delete UCMs added to to the Call Manager (UCM) group or re-order UCMs in the group.
   Priority (Mandatory)	Enter the priority number for this UCM in the group. The smaller the integer, the higher the priority.
   Selected Cisco Unified Communications Managers	This field displays the UCMs in the Cisco UCM group.

6. Click Save.

   New UCM groups now appear in the list view of Call Manager Groups. You can delete Call Manager Groups from the list if required.

   Note

   To verify that the UCM is deployed in Shared Mode:

   • Go to UCM Servers.
   • On the Publisher tab, verify that the Multi-Tenant field is set to Shared.
