Call2Teams - Customers


Customers may prefer not to grant access rights to the Call2Teams portal to configure the service for them, and instead wish to undertake the setup process manually. This article describes the process.


This manual setup process should be undertaken by a Microsoft 365 administrator who has good experience using PowerShell.

If there is any existing PSTN integration set up on the tenant, then these instructions will need to be modified by a Microsoft 365 PSTN voice expert to ensure they do not impact the existing configuration.

The configuration is split into two sections: 

  • Tenant Configuration, which is performed once on initial setup and again whenever a new region is required
  • User Configuration, which is performed for each user as they need to be enabled for voice.
