What is a phone system for a small business?
A small business phone system is the technology that lets your team make and receive business calls professionally. Modern systems run over your broadband (VoIP/cloud) rather than old copper lines, so one business number can ring a desk phone, a laptop and a mobile at the same time.
For a small business that means you sound professional, never miss a call, and do not need to give out your personal mobile number. It also means you are ready for the UK PSTN switch off in 2027, when traditional analogue lines are withdrawn.
