The deployment and configuration of the Microsoft Teams Apps is done from the Microsoft 365 / Office 365 Teams Admin Centre, a familiar interface to most IT Departments, while the integration between the 1&1 Versatel Platform and the  Microsoft Phone System is configured via PowerShell, which can be done by your Microsoft Partner.

The required 1&1 Business Phone components to enable this integration with the 1&1 Versatel Telephone System can be ordered via a separate order form from 1&1 Versatel.

To activate the "1&1 Versatel Premium Integration for Microsoft Teams" bolt-on, the following prerequisites must be met:
