Voice and video calling

Calling for Microsoft Teams refers to the capability of people to make and receive calls in Microsoft Teams. Microsoft 365 subscriptions include Calling for Microsoft Teams from one Teams app to another Teams app. Making and receiving calls to and from landlines and mobile phones on the public switch telephone network (PSTN) in Teams is available with an add-on like Microsoft 365 Business Voice or is included in Microsoft 365 E5. These options provide a cloud-based phone system in Teams with features such as hold, blind and safe transfers, and reporting features for professionals who manage calling solutions.

A calling plan provides users with a primary phone number and calling minutes to make and receive phone calls. A domestic calling plan is included in Business Voice or can be added onto Microsoft 365 E5.¹

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 through a certified session border controller (SBC) to Microsoft 365 and the phone system. This will be available in any country where Microsoft Teams and the phone system are licensed. Direct Routing is part of the Teams-compatible phone system.

There are two offers for small and medium-sized businesses. Microsoft 365 Business Voice with a calling plan combines a phone system, audio conferencing, and a domestic calling plan.¹ Microsoft 365 Business Voice without a calling plan combines a phone system and audio conferencing, which requires a calling plan from a service provider.

For enterprises: A phone system and audio conferencing are included in Office 365 E5 and Microsoft 365 E5. Calling plans can be added on, or they can all be purchased separately.

Business Voice with a calling plan is currently available in the US, UK, and Canada. Calling plans are available for enterprises in the US, UK, and Canada as well as Belgium, France, Germany, Ireland, Netherlands, Puerto Rico, and Spain. Business Voice without a calling plan is available in over 70 countries, everywhere audio conferencing is available. A phone system for enterprises is available in over 120 countries, everywhere Microsoft 365 is available.

The product features and experience are the same across the offers for small and medium-sized businesses and enterprises. Pricing and availability differ.
