We will help you deploy, configure and set up Cloud Phone System & Enterprise Voice in Office 365. This will allow a Teams user to place and receive PSTN (Public Switched Telephone Network) calls and have access to PBX features. Cloud Phone System allows you to replace your existing PBX system with a set of features delivered from Office 365 and tightly integrated into your organization's cloud experience.

Cloud Phone System is the Microsoft technology for enabling call control and PBX capabilities in the Office 365 cloud with Microsoft Teams clients. Skype for Business clients, while still supported by Microsoft are outside of the scope of this service. Cloud Phone System allows you to replace your existing PBX system with a set of features delivered from Office 365 and tightly integrated into your organization’s cloud experience.

With Phone System, your users can use Skype for Business Online and Microsoft Teams to take care of basic call control tasks, such as placing and receiving calls, transferring calls, and muting and un-muting calls. Phone System users can click a name in their address book, and Skype for Business or Microsoft Teams places a call 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 Skype for Business and Microsoft Teams. For admins, Phone System provides the ability to manage calling within the same admin console used for messaging, collaboration, and so on.

The project provides enterprise voice functionality to Teams in Office 365 / Microsoft 365 with the following features:
  • PSTN Calling using Teams
  • Call hold/retrieve
  • Call transfer
  • Call forwarding
  • Camp On
  • Distinctive Ringing
  • Simultaneous Ringing
  • Voicemail
  • USB peripherals (such as a USB phone)
  • Delegation (Boss/admin)
  • Team Call
  • Basic Call Policy
