Phone2Teams is a Microsoft 365 integration that connects Microsoft Teams to any IP phone system. This allows users to make and receive calls on the Teams App using the same lines as your current phone system.
Keep your existing phone system and enhance it with feature rich Microsoft Teams Apps.
You will be able to use the Microsoft Teams dial pad as your current PBX on the desktop and on any mobile phone. You will be able to communicate with your PBX from within Teams – Portals, Feature Codes, Soft-Keys. Nothing else will change with your current telephone – you can have an application in Teams if you want.
