What is digital voice? A simple guide to the new home phone service

If you’ve had a home phone for many years, you may have heard that things are changing. Across the UK, traditional landlines are being replaced with something called digital voice.

This guide explains what digital voice is, what other names it goes by, and what it means for you, in plain, simple language.

What is digital voice?

Digital voice is a way of making phone calls using your internet connection instead of the old copper telephone lines.

You might also hear it called:

• Internet phone
• VoIP (Voice over Internet Protocol)
• Digital landline
• Broadband phone service

They all mean the same thing: your voice is turned into digital data and sent over the internet, rather than through traditional phone wires.

The UK’s old telephone network (called the PSTN) is being switched off by January 2027.

This is happening because:

• The old system is becoming outdated and harder to maintain
• Most modern communication already uses the internet
• Digital systems are more reliable and flexible

This means that everyone with a home phone will need to move to digital voice over the next few years.

Will my phone still work?

In most cases, yes.

Many people can:

• Keep their existing phone number
• Continue using their current handset
• Use a small adapter (if needed) to connect their phone to the internet router

For most households, the change is simpler than it sounds.

What are the benefits of digital voice?

Digital voice services can offer several advantages over traditional landlines:

Clearer call quality

Calls are often sharper and easier to hear.

Lower costs

Many services are cheaper than older landline packages.

Protection from nuisance calls

Some providers include features that help block scam or unwanted calls.

Flexibility

You may be able to:

• Take calls on different devices (like a mobile phone)
• Use your number even when you’re away from home

Are there any things to be aware of?

It’s important to understand a few key differences:

It needs an internet connection

Your phone will work through your broadband, not a separate phone line.

Power cuts

Unlike old landlines, digital voice may not work during a power cut unless you have a backup solution. Many providers offer options for this if needed.

Extra support is available

If you rely on your phone (for example, for health or safety reasons), providers can offer additional help and guidance.

Is digital voice difficult to set up?

For most people, the setup is straightforward.

It usually involves:

1. Connecting your router
2. Plugging your phone into the router (or an adapter)
3. Following simple instructions from your provider

Many providers also offer step-by-step support if you’re unsure.

How to choose the right provider

When comparing services, it helps to look for:

• Reliability – a stable connection and good customer reviews
• Clear pricing – simple plans without unnecessary extras
• Helpful support – especially if you’re not confident with technology
• Safety features – such as call blocking

Reassurance: you won’t be left behind

This change is happening across the whole UK, and providers are expected to support customers through it.

If you’re unsure about anything:

• You can ask your provider for help
• You can take your time before switching
• You can get advice tailored to your situation

You’re not expected to figure it all out on your own.

In summary

Digital voice is simply a new way of making phone calls using the internet instead of traditional phone lines.

Although the change may sound technical, for most people it:

• Works much like a normal phone
• Keeps your number the same
• Offers clearer calls and helpful features

With the 2027 switch-off approaching, understanding what digital voice is can help you feel more confident about the change.

Frequently asked questions about digital voice

Can I keep my phone number?

Yes, in most cases you can keep your existing phone number.

This process is called number porting. It simply means your provider transfers your current number from your old landline service to your new digital voice service.

• You won’t need to tell friends or family a new number
• The switch is usually handled for you by your provider
• There is normally little to no disruption during the change

Can I keep my current phone?

In most cases, yes.

Many existing home phones can still be used with digital voice by using a small adapter (sometimes called a VoIP adapter), which connects your phone to your internet router.

Alternatively, you can choose to:

• Use a new digital-compatible phone
• Or plug your phone directly into the router if it has a phone socket

If you’re unsure, your provider can let you know what will work best with your current setup.

Will it feel different to use?

Not really.

For most people, using digital voice feels just like using a traditional landline:

• You still pick up the handset and dial as normal
• Calls come through in the same way
• Your number stays the same

The main difference is simply how the call is carried behind the scenes.

What happens during a power cut?

Digital voice relies on your internet connection, so it may not work during a power cut unless you have a backup solution.

If this is a concern, you can:

• Ask your provider about battery backup options
• Use a mobile phone as a backup
• Check if you qualify for additional support

Do I need to be good with technology?

No.

Digital voice is designed to be simple to use. Many providers offer:

• Step-by-step setup guides
• Telephone support
• In some cases, in-home assistance

You won’t be expected to manage it on your own.
