Teams Phone System for Microsoft 365

Teams is the fastest growing application in the history of Microsoft. Teams is included in all Microsoft 365 Enterprise plans and most Business plans. Companies using Microsoft 365 can now upgrade Teams to a complete cloud-based business phone system.


Teams Phone System allows you to replace your existing PBX system with a set of integrated business phone system features tightly integrated with Microsoft 365 and delivered from the Microsoft cloud.

Companies can easily migrate to Teams Phone System simply by adding the appropriate Microsoft 365 licenses, many of which are already included in Microsoft 365 Enterprise plans.
