What is Cloud PBX? Cloud PBX, also known as hosted PBX, is a phone system that operates over the internet rather than through traditional on-premises hardware. The main purpose of it is to manage your inbound and outbound calls using VoIP (Voice over Internet Protocol) technology, providing you with a full suite of communication features without the need for physical infrastructure. The “cloud” aspect means the system is hosted and maintained by a service provider, reducing the burden on your IT resources.
How Cloud PBX works
Calls are made and received over your internet connection
The Cloud PBX platform handles call routing and features
Users connect via desk phones, mobile apps or desktop software
Admins manage everything through a web portal
The provider maintains the infrastructure, security, updates and reliability — not your internal IT team.
