No need for a second phone!

Your employees do not need to use a second phone to make calls. By putting the mobile number inside Microsoft Teams, Onoff Business allows you to call directly from the Microsoft Teams mobile application. Your employees can manage all of their communications directly from a single phone.

Quick set up with Microsoft 365

Onoff Business automatically syncs with Microsoft 365 Active Directory. Assign professional numbers to your employees using Microsoft Teams. Keep the ownership of your mobile telephone lines and reassign any number in one click in the event of an employee leaving.
