What is a PBX Phone System? Private Branch Exchange Explained

Understand PBX systems and cloud PBX benefits

Plans from $14.95/moNo contractsFree number porting

A PBX (Private Branch Exchange) is a phone system that manages internal and external calls for a business. It connects multiple extensions within an office to each other and to the outside phone network. Features like call transferring, voicemail, auto attendant, and extension dialing are all handled by the PBX.

Traditional PBX systems required expensive on-premise hardware and a technician to maintain. Cloud PBX (also called hosted PBX) moves all the hardware to the provider's data center — you just connect your phones to the internet. RingVersa provides a full cloud PBX with every plan, so you get enterprise features without buying or maintaining any hardware.
