What is Teams Phone?

Microsoft Teams Phone is Microsoft's technology for enabling call control and Private Branch Exchange (PBX) capabilities in the Microsoft 365 cloud with Microsoft Teams.

Teams Phone works with Teams clients and certified devices. Teams Phone allows you to replace your existing PBX system with a set of features directly delivered from Microsoft 365.

Calls between users in your organization are handled internally within Teams Phone, and never go to the Public Switched Telephone Network (PSTN)--thereby removing long-distance costs on internal calls.

For making external calls, Teams Phone provides add-on options for connecting to the PSTN.
