Teams Telephony

WaTech Teams Telephony Service

Phone System in Office 365 provides Phone Branch Exchange (PBX) capabilities through Microsoft Teams.

With Phone System, users can use Teams to place and receive calls, transfer calls, and mute or unmute calls. Phone System users can click a name in their address book, and place Teams calls to that person. To place and receive calls, Phone System users can use their mobile devices, a headset with a laptop or PC, or one of many IP phones that work with Teams.

Phone System can be connected to the Public Switched Telephone Network (PSTN) in one of two ways:

  1. Purchasing a Microsoft Calling Plan (domestic or domestic and international) for Office 365. Microsoft Calling Plan is an all-in-the-cloud solution with Microsoft as your PSTN carrier.
  2. Using WaTech's existing telephony infrastructure for on-premises PSTN connectivity.
