Teams Configuration
Once the integration is set up, voice calling is enabled in the Microsoft Teams app via the native dial pad, allowing users to make and receive external calls with their own phone number and extension on any Teams device.
See the Teams User Guide for details.
Voice Calling Policies
When the integration is set up, a number of calling policies are added to your Microsoft 365 account, which any Global Admin can see in the Voice section of the Microsoft Teams admin center.
Warning
Do not make changes to Voice policies and templates in the Microsoft Teams admin center. Any changes could break the integration and may be undone the next time the account is synced.
