CUCM Group Selection

Full HTML Help

Provider level administrators can manage the Default CUCM Group setting in a customer's Site Defaults:

• The least utilized Group can be calculated, in other words the group with the least number of phones can automatically be determined.

  In this case, the administrator can set the Default CUCM Group in the customer's Site Defaults to automatically be the least utilized group so that CUCM Groups are optimally assigned whenever a site is created.

• The current device utilization of customer CUCM Groups can be inspected. Device utilization is calculated by inspection of the Device Pools that belong to a CUCM Group of a CUCM cluster and the number of Phones in these Device Pools.

  The administrator can therefore inspect the CUCM Group counts and then choose a Default CUCM Group to be the Default CUCM Group in the customer's Site Defaults.

High level administrators carry out these tasks from the Customer Management > Advanced > CUCM Group Selection and CUCM Group Counts menus.

Select a CUCM Group

1. Log in as a Provider administrator and select Customer Management > Advanced > CUCM Group Selection.

2. The list of existing CUCM Group Selection configurations at the Provider hierarchy are listed.

   Click Add to create a configuration. A hierarchy pop-up will show to choose the customer hierarchy at which the configuration should apply.

3. Choose a Name for the configuration. The default name is the hierarchy name.

4. Choose an Algorithm to apply to the CUCM Group Selection:

   • If Use Default is selected, the Site Defaults doc is updated if necessary so that the Default CUCM Group is applied.

     Note: The CUCM Group called Default is always used when adding a Site unless the "Least utilized" algorithm has been selected. Default will also be the fallback CUCM Group in the event that all CUCM Groups have been excluded from the selection.

   • If Least utilized CUCM Group is selected from the Algorithm drop-down, options are available to include and exclude specific CUCM groups from the algorithm.

     • If no groups are included or excluded, all groups available at the customer hierarchy are considered by the algorithm.
     • If groups are added to the CUCM Groups to Include, only these groups are considered by the algorithm.
     • If groups are added to the CUCM Groups to Exclude, these groups are not considered by the algorithm, unless they have also been added to the Groups to Include.

     The table below summarizes the options and outcomes:

5. Click Save to save the configuration for the customer hierarchy. When a new site is created, the Default CUCM Group in the Site Defaults Doc is updated to reflect the configuration, so that any sites that are now created under this customer hierarchy will apply the calculated CUCM Group.

   Note that an administrator can override this calculated CUCM Group by manually updating the Site Defaults Doc.

Data model to control if the CUCM Group should be available for use. This is to allow for load balancing devices between CUCM Groups. Only one instance may exist at Customer level.
