Opt out of a call queue
When you're part of a 'call queue', such as the main school number, you will receive calls to that number in addition to anyone else that is in that queue.
The first person to answer gets the call.
However, in some circumstances, you may wish to remove yourself from the call queue for a period of time and not receive calls made to that number. You will still receive calls made directly to your number.
You can do this in Teams:
1. Go into the Settings page for Teams, and make sure the 'calls' section is highlighted on the left:

At the bottom of this page, you'll see the section called 'Call queues'.
In this example, you can see the IT Queue, which means this user receives calls made to the IT number in addition to their direct calls.
If your system administrator has allowed the option, you may be able to 'opt out' of the queue. If you have this option, you will see a on-off toggle where you can turn off the queue. If you do not see the toggle, as in the screenshot above, it means you do not have the option to opt out of that particular call queue.
