What is Microsoft Teams Direct Routing?

Direct Routing for Microsoft Teams allows your users to make and receive external phone calls directly from the Teams app — just like a traditional phone system. It connects Microsoft’s cloud with the public telephone network (PSTN) using a secure, certified connection.

This lets you replace Microsoft’s expensive Calling Plans with a more flexible, cost-effective solution — fully managed and supported by Yellowcom.
