Understanding Groups and call queue.

Groups

By default, any button press with "All users" as the selected action, will trigger calls to all users simultaneously that are not part of a group. If you want to direct calls to specific individuals, you can create customized groups.

Within a group, you have the flexibility to send video call notifications to all members at once or in a sequential queue (video calls only). If there's no response within 30 seconds, the system can automatically dial a designated phone number, depending on your settings. Alternatively, you can configure a group without users to bypass the video call process and initiate a phone call directly. 

After setting up your group, go to the Stations section and link the group to a button. This ensures that the button will exclusively call the assigned group and its associated phone number.

To create a submenu, simply associate more than one group to a button.

Please note the original administrator of the account cannot be added to a group.

When creating a group with MS Teams users, be sure to enable the call queue option to prevent a conference call where all users can join simultaneously. Alternatively, you can create the call queue within your MS Teams admin account and then import it as a regular user using the Microsoft AAD search box. Don't forget to enable the "MS Teams Call Queue" option to ensure proper call handling.
