Groups allow an administrator to bundle extensions together by their own criteria, these could be things such as branches, positions or departments. These groups are purely an aid within the TMS, but do not affect the workings of the PBX. Groups can allow the administrator to better analyse costing and usage. 

The page also indicates how many extensions are not assigned to a group, by showing them as “Unassigned”, and provides a link to the extension manager to be able to assign them.

To create a group, click on the “Add Group” and provide a name for the new group. Once the name is saved, extensions can be added to the group by selecting the “Assignment” button. From here extensions can be dragged over to the “Assigned” pane to add them
