Get a hosted telephony quoteHosted telephony — a business phone system that runs in the cloud over your internet connection instead of on copper lines and a box on the wall — has gone from a nice-to-have to the default. Openreach stops selling the old analogue and ISDN lines, then switches them off by 31 January 2027, so every UK business that still has a traditional phone line will be on some form of VoIP within the year. The guides below are written for the person who has to choose, buy and live with that system: plain English, UK pricing, and the questions providers would rather you did not ask.
Start with what hosted telephony is and how it works, which explains VoIP, cloud PBX and SIP without the jargon. Then read what hosted telephony costs in the UK — per-user pricing, what is bundled, what is extra and the worked examples that let you hold a real quote to account — and how to choose a provider without being sold the wrong thing. If your team lives in Microsoft 365, Microsoft Teams Phone for UK businesses compares Operator Connect, Direct Routing and Calling Plans against a conventional hosted system.
The rest of the cluster covers the practical detail: keeping your numbers when you move, the internet connection VoIP actually needs, call recording and compliance, SIP trunking versus hosted VoIP for businesses that already own a PBX, and what the PSTN and ISDN switch-off means.
