4. Configure the phone number
After you’ve created the user and assigned licenses, you must configure the user’s online phone settings.
You can configure the phone number by using the Teams admin center or by using Teams PowerShell. Here, as an example, using Teams admin center.
- Select a user.
- Under Account General information, select Edit.
- Under Assign phone number, from the Phone number type drop-down menu, select Direct Routing.
- Enter an assigned phone number and a phone number extension if applicable.
- Select Apply.
The account general information will now show the assigned phone number and Direct Routing as the phone number type.
