What is a cloud-based phone system?

A cloud-based phone system is a Voice over IP (VoIP) system that is hosted over the internet. Unlike a traditional phone system or PBX, the technology and infrastructure that enables a communication network in a cloud-hosted system is located offsite and managed by a third party service provider.

How does a cloud-based phone system work?

A cloud telephone system converts a voice signal to small packets of data, which can then be sent and received – just like any data – over the internet. A hosted PBX system manages the routing of the call.

More on Business Mobile


Cloud technology refers to the delivery of computing and communications services over the internet. Instead of maintaining on-site, hardware-heavy systems to manage and process data, businesses can migrate these services online. The benefits of cloud technology include cost savings, fast integration, almost unlimited flexibility and scalability, and greater system reliability.

You’ll need a fast, reliable internet connection such as fibre broadband for your cloud calling system. The precise bandwidth you’ll need however depends on the number of concurrent calls your business is likely to make, as well as how much video calling is required. More calls and more video = more bandwidth.

Though this depends on your specific telephony application and requirements, in most cases cloud does indeed prove to be more cost-effective than on-premise systems. This is because cloud hosted systems do not require the upfront and ongoing infrastructure and hardware upgrades and maintenance of on-premise systems, especially where scalability or functional changes to the system are required to meet evolving business needs.

In addition to cost savings, cloud technology is also fast to set up and integrate, is flexible and scalable to your business requirements, and can help your manage your employees workflow and communications more efficiently, leading to both productivity increase and a better customer experience.
