The basics

What a cloud phone system actually gives you

Plain English, no jargon — here's what changes when you move off traditional lines.

A cloud phone system replaces the physical line into your building with a service that runs over your internet connection. Your business number stays exactly the same — it simply stops being tied to one socket on one wall. That single change is what lets a call to your 0113, 0161 or 020 number ring a mobile on site, a laptop at home and a desk phone in the office at the same time.

For most small businesses the practical benefit is fewer missed calls. On a traditional line, a call that isn't answered at the desk is gone. With a cloud system you decide what happens next: ring a second person, roll to an out-of-hours message, or drop a voicemail into an inbox as an audio file you can listen to between jobs. You can also dial out showing the business number rather than a personal mobile, so customers save the right number in the first place.

The second benefit is cost predictability. Traditional lines carry line rental plus per-minute charges that vary month to month. Our plans start at £19 per user per month with UK landline and mobile calls included, so the bill is the number of people who answer the phone multiplied by a fixed figure. There are no setup fees and no charge to bring your existing numbers across. If you want to see the difference against your current bill, the full pricing breakdown sets it out per plan.

Nothing about this requires new cabling or a fibre upgrade. A standard business broadband connection carries several simultaneous calls comfortably — connection quality matters far more than raw speed, which we cover in the guide to the broadband you need for VoIP.

Who we work with

Built around how UK small businesses actually work

The setup differs depending on who answers the phone and where they are.

Sole traders and trades

One advertised number on the van and the website, ringing your mobile app while your personal number stays private. Missed calls arrive as an email you can act on the same day rather than a lead that quietly went elsewhere. See phone systems for trades.

Offices and small teams

A main number that rings reception first and spills over to the wider team, with departments, hold music and opening-hours routing. Add or remove a user when someone joins or leaves, without an engineer visit. Compare the options on UK business phone systems.

Remote and multi-site

One system across every location and home worker, so an internal call between sites is just an extension. Local numbers for each town you trade in, all landing in the same place. More on phone systems for remote workers.

Why now

The old network is being retired

Analogue and ISDN services are being withdrawn, so most businesses will move at some point.

Traditional analogue lines and ISDN circuits are being phased out across the UK, and once your exchange is done there is no option to renew. Every business still on those services will need a digital replacement, which means the only real decision is whether you move on your own timetable or someone else's. Moving early tends to be calmer: you choose the port date, test the new setup on a temporary number first, and train the team before anything changes.

Be aware of one honest detail. Porting a number is a handover between two networks, and there is a short window on switch day when the number has left the old provider and is not yet live on the new one. It is usually minutes, but it is not zero — we plan around it by advertising a mobile for the day and picking a quiet mid-week slot. Any provider promising a completely seamless port is overselling it.

If you are not sure what you currently have, we will check it for you. The PSTN replacement guide and the ISDN switch-off deadline page explain what is ending and when, and switching from BT walks through the move itself. Alarms, lifts and card machines often sit on the same lines, so those get checked as part of the assessment too.
