What is PBX?

Call someone, transfer them, or put them on hold—it all happens through a private branch exchange (PBX). A PBX is the internal network of software and hardware that manages business phone systems.

How does PBX work?

Choose on-premises or in the cloud for your PBX, and it will connect to your phone company or internet provider to handle incoming and outgoing calls.

“Teams has enabled us to reduce our legacy telephony footprint and stop putting phones on desks. It reduces costs and more importantly, provides a much better, ‘click to join’ experience for our people.”

 

Thomas Bruss
Director of Global IT, Digital Worker Technology, Accenture

 

 

 

“We were excited about the improved quality of voice and video. We also liked the idea of having one tool for collaboration―and on a larger scale than Skype for Business Online.”
