Traditional copper landlines are on their way out in the UK. With the analogue network being retired, with Openreach working towards a January 2027 deadline at the time of writing, homes, sole traders and small offices are all asking the same thing: what replaces the landline?

For most, the answer is a VoIP landline, or a phone that works over broadband. Here's how it works, what to buy and where a VoIP reseller in the UK can help.

What Is a VoIP Landline?

A VoIP landline gives you a familiar UK phone number, geographic (such as 020 or 0161) or non-geographic, but delivers calls over the internet rather than copper wiring. You can use a desk handset, a cordless phone or an app on your mobile or laptop.

Callers dial as normal. They won't know or care that the call is routed over broadband.

VoIP Phones for Home Use in the UK

If you're looking at VoIP phones for home in the UK, you have three main options.

Analogue adapter with your existing phone

An adapter (ATA) plugs into your router and lets an ordinary handset work over VoIP. It's often the cheapest way to keep a favourite cordless phone.

Dedicated IP or SIP handset

A dedicated VoIP phone connects directly to your network. Handsets from established manufacturers offer HD audio, programmable keys and better integration with business systems. This is often the best option for home workers who take many calls.

Softphone app

An app on your laptop or smartphone can act as your office phone, with a headset. It's flexible and inexpensive, but it depends on your device and connection, so many people pair it with a desk phone.

Whichever you choose, check compatibility with your provider before buying. A basic "voipphone" search will show many devices, but not all work with every service.

Why Hybrid Teams Benefit

Hybrid working exposes the weakness of old phone systems, which tie numbers to a physical office. Cloud telephony separates the number from the location.

Staff can answer the main business line from home, transfer calls to colleagues, and use voicemail-to-email without giving out personal mobile numbers. Reception can route calls to whoever is in the office that day.

For a small business, this often means the difference between looking like a one-person operation and a professional company.

Cloud PBX for Small Offices

A cloud PBX handles the features once found only in large office systems:

• Auto-attendant (press 1 for sales, 2 for support)

• Ring groups and call queues

• Out-of-hours routing

• Call recording, where lawful and properly disclosed

• Mobile and desktop apps

These tools make small firms look larger and help them manage missed calls. A plumbing business, for example, might route calls to whoever is on shift, then fall back to a mobile if nobody answers.

What to Check Before Switching

Broadband reliability

Voice needs a steady connection. If your home or office broadband is patchy, fix that first. Consider a backup mobile connection for critical numbers.

Power cuts

Copper landlines could continue working during power cuts, while VoIP depends on your router and power. Consider a small battery backup for your router, and make sure mobile phones are available for emergencies.

Emergency calls

Make sure your provider explains how 999 calls are handled and how your address is registered. Keep the address up to date, especially for home workers.

Number porting

Confirm you can keep your existing number, and how long the transfer will take. Avoid cancelling your old line before the port is scheduled.

Vulnerable users

If someone in your household relies on a landline for telecare or alarms, check compatibility before switching.

Where a Reseller Fits In

A VoIP reseller UK can be a convenient way to buy all of this in one place: numbers, handsets, apps and setup support. For a business with a mix of office and remote users, having a single supplier managing lines, devices and support saves time.

When comparing options, Wavetel Business is one provider worth reviewing, particularly to see how its service handles number porting and multi-user setups for small and growing teams.

Example: A Two-Person Design Studio

A studio with one office and two home workers wants to keep its 020 number. They choose a hosted service with a desk phone for the office, softphone apps for home, and a main-line auto-attendant.

Callers reach the studio however the team is working. The partners can view missed calls and voicemail from anywhere. If they hire a third person, they add a user in an admin portal rather than arranging a line installation.

FAQs

Can I keep my landline number with VoIP?
In most cases, yes. Most UK geographic numbers can be ported to a VoIP provider, but confirm timescales before cancelling your current service.

Do I need a special phone?
Not always. You can use a compatible handset, an adapter with your existing phone or a softphone app.

Will VoIP work during a power cut?
Not unless your router and equipment have battery backup, so plan for a mobile fallback.

Is VoIP good enough for business calls?
With decent broadband and proper configuration, yes. Call quality is generally comparable to or better than older lines.

Conclusion

The move from copper to VoIP is a practical shift, not a technical headache. Choose devices that suit how you work, check your broadband and power resilience, and make sure emergency calling and number porting are clear before switching. Done properly, a VoIP landline offers more flexibility for home and hybrid working than the line it replaces.
