Callto365 announces the World’s first PABX (PBX) for Microsoft Teams

16 July 2024, The Netherlands – CallTo365 announces the launch of the World’s first Teams Private Automatic Branch Exchange (PABX). Via this Teams Calling platform, organizations can distribute voice calls to agents using Teams.

Microsoft Teams is swiftly becoming an essential part of the everyday business toolkit, yet it lacks the native ability to handle enterprise telephony. CallTo365’s PBX for Teams means that businesses can enhance Team’s capabilities to include all the features expected of a modern telephone system. 

By enabling the handling of voice calls directly through the Teams client, businesses of any size can unlock new value sources and even greater levels of productivity. CallTo365’s PBX for Teams makes it possible to classify incoming calls, collaborate on calls, integrate virtually any CRM, and provide a variety of advanced routing options that ensure the most efficient service is provided to each caller. 


“CallTo365 is very proud to introduce the world’s first Teams PABX. By converting Teams Calling into a full-function telephony system, this innovation paves the way for numerous organizations to integrate and streamline their Teams-based processes alongside first-class call handling within a single, unified environment. Callers can be efficiently routed to the right person every time, and queries can be handled in a professional way with the best tools at the agent’s fingertips.”

With this new PABX for Teams, businesses can route their incoming and outgoing calls in the most efficient way, using a solution that’s built for their evolving needs. CallTo365’s Team PABX allows organizations to leverage technologies such as Interactive Voice Response (IVR), Automated Call Distribution, Call Queuing, and more – alongside the numerous native benefits of Teams Calling.
