The User Extensions tool allows an administrator to specify extensions for users for inbound signals. The administrator is configured to set the extension for a specific service.

For example, this tool could be used to configure the fax extensions for employees of a company.

The extension is known as a “DID number”.

Administering DID numbers

Administrators can only assign DID numbers in their configured range. It is not possible to assign the same DID number to more than one user. Administrators can only assign DID numbers for users in their group.

Click Filter and enter the user ID to easily locate users.

Select Show users with no DID number in the filter to display users without a DID number.

Click Check all DID numbers for the group to scan all users in the group and check if the DID number is in the specified range, or if the same DID number is assigned twice. If a problem is found, the name of the corresponding user will be displayed.

Click Show Total Number of Used DIDs to scan all users in the group and count the number of used DID numbers. The number of DIDs is displayed in popup window.
