What is a cloud phone system?

A cloud phone system is a business phone service that lives on the internet rather than on a box of hardware in your building. The calls, features and settings are all managed off-site by your provider, and your team connects through handsets, computers or mobile apps. You get the phone system without owning and maintaining the equipment behind it.

How it works in practice

Each person has an account that travels with them. They can take and make calls on a desk phone in the office, the same number on a laptop at home, or an app on their mobile out on a job — all behaving as one extension. Changes like adding a user or a call queue are made in software, instantly, rather than waiting for an engineer.

Why businesses move to it

Three big reasons: it suits hybrid and remote working (your number isn't chained to a desk), it's predictable to budget (a monthly per-user fee rather than big hardware spend), and it's ready for the 2027 landline switch-off by design. It also tends to bundle in features — call recording, integrations, multiple channels — that cost extra on older systems.

What you need to run one

A reliable internet connection and not much else. Because call quality depends on that connection, it's worth having a line that prioritises voice and a failover that kicks in if the main connection drops — so your phones keep working even on a bad day.
