Cloud Communications Terminology

Private Branch Exchange | PBX

A private branch exchange (PBX) is a business phone system with multiple inbound and outbound lines with features like call routing, queuing, and management, plus extension numbers, voicemail, and more. These features are traditionally part of a hardware solution managed by the IT team.

A hosted PBX service offers the same features, as well as additional advantages such as greater scalability. Instead of connecting to an internal server, however, your phones connect via the internet using Voice over Internet Protocol (VoIP) servers hosted in the cloud. Telecommunication experts manage the system, freeing up your IT team to focus on your core business.
