What Is Phone System?

Microsoft Teams Phone System, What Is It?

Phone System enables call control and PBX (Private Branch Exchange) capabilities fully in the cloud with Microsoft Teams.

With Phone System, users can utilise Teams to place and receive calls, transfer calls, and mute or unmute calls both internally and to the Public Switched Telephone Network (PSTN). Phone System users can click a name in their address book and place Teams calls to that person. To place and receive calls, users can simply use the dedicated Teams app on their mobile devices, a headset with a laptop or PC, or one of many certified IP phones that work with Teams. Administrators can manage calling options and settings from the Teams Admin Centre, the same console used for messaging, collaboration and so on.
