Teams Phone: how to set business hour

Hi @Liu, Hao

To set up business hours for Teams Phone, you can customize call flow after hours or on holidays. You can also create an auto attendant that redirects calls to Teams phones within a specified amount of time.

The steps to add an auto attendant are:

1. Set up general information.
2. Set up a basic call flow.
3. Set up an after-hours call flow.
4. Set up holiday call flows.
5. Set up dial scope.
6. Set up resource accounts.
7. Set up authorized users.
