What is cloud PBX?

A cloud-based Private Branch Exchange (cloud PBX) is a phone system that delivers advanced calling features and unified communications using Voice over Internet Protocol (VoIP) technology. Cloud PBX systems are hosted by service providers, eliminating costly on-premises hardware since they are billed on a monthly or annual subscription.

Compared to traditional landlines, businesses get greater flexibility, scalability, and reliability with a cloud PBX service. It provides professional features like auto-attendants, call routing, integrations, and video conferencing.

With a cloud PBX solution, you only need an internet connection to make and receive calls, send messages, and work from anywhere.
