WHAT IS A MICROSOFT TEAMS PHONE SYSTEM?
The PBX (private Branch Exchange) in Microsoft’s product suite is the technology that enables call control and phone system functionalities within the Microsoft Teams ecosystem. Users can access the Teams Phone System features using either Apps on their mobile devices, clients on the laptops or PC’s or via Microsoft Teams Certified Devices.
Calls can be placed between users within your organisation internally within you business regardless of the staffs locations, meaning that there is no interaction with the outside world, and therefore no call costs. To make calls outside your business, you will need to add products such as Teams Direct Routing – which is a virtual phone line from your Teams environment to the outside world.
