The 2027 copper cable landline switch-off

The 2027 copper cable landline switch-off: What the end of the PSTN network means for rural communities

Much like the stone walls, thatched roofs and local pubs are fixtures of rural villages in Dorset, Somerset, Wiltshire and Hampshire, so too are traditional copper landlines.

For decades, the traditional copper landline has been right there with them as a reliable presence connecting your home phone on the hallway table or the kitchen wall.

However, a significant change is coming to the way we stay in touch. In January 2027, the UK’s old copper telephone network, known as the PSTN (Public Switched Telephone Network), will be retired. Instead, our home phones will be connected over the same cables as our internet.

At Wessex Internet, we know that for many of our customers, the landline is essential. It’s a tool for those living in areas where mobile signal is non-existent. But a switch to an internet home phone doesn’t mean a drop in connection. We want to clear up the confusion and show you why this change doesn't have to be daunting.

Why are the old wires going away?

Simply, the PSTN is getting too old to maintain. These copper cables have been tucked away under our country lanes for a very long time. They are prone to dampness and degrade over distances, and finding spare parts for the ancient exchange equipment is becoming nearly impossible.

Technology moves on so that the service can stay reliable. By moving phone calls to the same fibre optic cables that carry your broadband, the whole system becomes much more resilient.

What is digital voice?

You might hear people talking about VoIP (Voice over Internet Phone) or Digital Voice. All this means is that your phone calls travel as data over your internet connection rather than as electrical signals over the old PSTN copper. At Wessex Internet, we call this your Wessex Telephone.

The transition is much simpler than most people expect. Instead of plugging your telephone into the circular or rectangular socket located on your skirting board, you plug it into the back of your broadband router.

The experience of making a call remains exactly the same. You pick up the handset. You hear a dial tone. You dial the number. The person on the other end won't notice a difference, except perhaps that the line could sound much clearer.

Keeping your number and your handset

One of the biggest worries we hear from residents in places like Wool, Shaftesbury or the Wylye Valley is about their phone number. Many families have had the same number for forty years. It’s printed on business cards and memorised by family members.

The good news is that you can almost always take your number with you. When you move to a digital service like Wessex Telephone, we move your existing number over to the new system.

As for your physical phone, most modern cordless handsets (the ones with a base station that plugs into the wall) will work perfectly well with a digital setup. You won't necessarily need to go out and buy a new internet phone.

Supporting our most remote neighbours

The transition to digital lines is an essential and inevitable step for rural communities; but there will be a shift in how we handle outages. When everything is digital, there’s a heavy reliance on electricity. If there’s a bad storm that knocks out the power, for example, a traditional PSTN phone often keeps working because it draws a tiny amount of power from the exchange.

Digital phones rely on your home's electricity to keep the router running but there are workarounds to keep you connected. At Wessex Internet, we don't believe in leaving anyone stranded. For customers who are in areas with no mobile signal or those who are deemed ‘vulnerable’, we are able to offer battery backup units.

These small devices keep your router and therefore your phone active for at least an hour during a power cut. This ensures you can still reach emergency services or family if the lights go out.

The Wessex Internet way: Local support for a national change

Big national providers often handle these transitions with automated letters and distant call centres. That isn’t how we do things here. We are based in the heart of the countryside we serve. Our engineers are the same people you see in the local shop. Our support team sits in our office in Dorset.

We understand that for a small business running out of a converted barn, a working phone line is essential for trade. We treat every installation with the care it deserves. We ensure that your broadband and your telephone service are working perfectly before we consider the job done.

One of the most common questions we hear at community meetings across the region is about the practicalities of the physical installation. People are understandably protective of their gardens and their driveways.

When we talk about moving a landline to a digital system, it often involves bringing a new fibre optic cable right into the house. Unlike the old copper wires that were often strung loosely from poles or buried in shallow, crumbling conduits, our fibre is built to stay.

We use specialised machinery that allows us to install these cables with very little mess. In many cases, we can use a directional drill or mole-plough to tuck the cable under a lawn or use existing ducting already in place. This means the transition to a modern phone service does not have to involve a massive construction project on your doorstep.

Once the fibre is inside, it connects to a small box on your wall. This box is the new heart of your home communications. Your telephone service will come directly out of the router we provide, which acts as the bridge between the outside world and your handset.

For small businesses operating in rural Somerset or Wiltshire, this change brings features that simply were not possible on the old network. Many local firms have struggled for years with noise on the line or dropped calls during heavy rain.

Because digital voice data is transmitted as light through glass fibres, it is immune to the electrical interference and moisture that plague copper. A business can now have multiple lines or extensions without needing a massive physical switchboard in the office.

This allows a small farm shop or a local consultancy to handle several calls at once. This ensures they never miss a customer.

Switching to a VoIP

The security of the connection is another area where the new system provides a benefit. The old PSTN network was increasingly vulnerable to physical faults that could take days or weeks to locate and repair. Because our network is monitored digitally, we can often see a problem before you even notice your phone has a dial tone issue.

Our local engineers can pinpoint exactly where a fault lies. This is a far cry from the days of technicians hunting through miles of hedgerow to find a broken wire.

For those who are worried about the technical side of plugging it in, our engineers do not just leave a box on your doorstep and drive away. We make sure that your main telephone is connected and we stay on-site until the service is active.

We know that for a resident in a quiet corner of Hampshire, being without a phone for even an afternoon can feel isolating. Our goal is to make the switch feel like a non-event.

As 2027 approaches, the national conversation around the switch to an internet home phone will only get louder. There will be plenty of letters from big corporations and confusing adverts on the television, but with Wessex Internet the switchover will be pain-free.

The support you need is available right here in the heart of Dorset, near Blandford. We have been part of these communities for fifteen years; and we intend to be here for the next fifty, keeping our villages talking.
