What is a user group?

User groups are containers of contain individual users and they often normally mimic the organisational structure of your company, allowing senior management you to report on calls by department. Access to the Directory can be restricted to one specific user group, so that managers can report only on their own department. For information on how to apply  these restrictions, refer to the Web users sectionrun reports on, and restrict access to, parts of the TIM Plus directory.

The Discovered Users folder

When you first configure the system and your extensions start to populate the Directory, a default folder, called Discovered Users is created automatically in the system. Its function is to pick up and store the newly discovered extensions and if renamed or deleted, it will be recreated in the Directory, as soon as a new extension is being picked up.
When you have created your own user groups in the Directory, you can move extensions from the Discovered Users folder to the newly created ones. For information on how to move users from one group to another, check the Moving a user between two groups sectionA special user group - Discovered Users - is automatically created to harvest hitherto-unknown user information from the call data received from your telephone system.

 Over time, when users have accumulated inside the Discovered Users folder, you can create your own user groups based on the structure of your organisation, and move individual users into the new groups.
