Calling in Teams refers to the capability of people to make and receive phone calls in Teams with features such as hold, and blind and safe transfers, and for professionals who manage calling solutions, which makes for great reporting.

Your organization will need to use Microsoft Teams as your calling solution. Additionally, your organization will need to use a phone system as part of E5 or acquire as an add-on. You will also need to choose a Calling Plan, Direct Routing, or a combination to make and receive calls.

Direct Routing allows customers to connect their telecom voice trunks directly to Microsoft 365 so people can make and receive calls. Customers can work with their local telecommunications provider to connect their voice trunks via a certified Session Border Controller (SBC) to Microsoft 365 and Phone System. This will be available in any country where we license Teams and Phone System. Direct Routing is part of the Teams-compatible Phone System.

A Calling Plan is an add-on telephone service that, when combined with Phone System in Microsoft 365, can become the voice solution for your entire organization. A Calling Plan provides people with a primary phone number and lets them make and receive phone calls.
