Calls on Teams is a unique add-on to Office 365 which integrates any existing phone system (PBX) with Office 365 enabling the Calls feature within Microsoft Teams or a full Microsoft Teams install using independent SIP trunks.
Allowing your staff to make and receive calls from your existing phone system using the Microsoft Teams app on any device, wherever they are. You get to keep all the existing numbers, routing and call centre functionality configured in your phone system. Alternatively, we can look at a full Teams integration without the expensive tie into Microsoft call plans.
