PSTN calling in Microsoft Teams can be enabled in two ways
Add Calling plans to Microsoft 365 licenses in Teams itself (if available in your Country). To be able to call from a mobile phone via PSTN in Teams, users must have 1:1 calling enabled in Teams and must be using a Teams client supporting 1:1 Teams Calling. Next, you need to be able to enable the Dial Plan tab in Teams. And the admin must provision the users for Calling plans. Unfortunately, this feature is not available in Europe.
The best way (available worldwide) is to add Calling plans from your local Telephony Provider who will enable Direct Routing to your Teams users for you. Very easy to implement.
