Microsoft Teams Phone System

Microsoft Teams Phone System, also known as Microsoft Teams Direct Routing, gives you the power to connect your business communications to Microsoft Teams, allowing you to make and receive calls from any number directly through the Teams app.

Adding in the functionality to be able to make and receive calls within Teams provides a simple unified communication and collaboration solution for most businesses. Your employees can make and receive calls directly from the same platform that they’re already using for a lot of their daily tasks – the familiar Microsoft 365 and Teams platform.

How does calling with Microsoft Teams work?
