VoIP Handsets UK: The Best IP Phones for Business in 2025

Switching to VoIP doesn't mean giving up desk phones. Most UK businesses still want a handset on the reception desk, in the office, or on the workshop floor — and the right IP phone makes your system feel exactly like a traditional phone system, only better.

This guide cuts through the noise. You'll find out what separates a VoIP handset from a regular phone, what features actually matter, and how to decide whether you need physical handsets at all.

The short answer:

• A VoIP handset plugs into your network via Ethernet — not a phone socket
• Entry-level models cost £40–70, mid-range £70–120, executive or reception phones £120–200+
• Yealink is the go-to brand for UK SMEs — reliable, affordable, widely supported
• PoE (Power over Ethernet) means one cable does the job — no separate power supply needed
• PSTN switch-off is January 2027 — IP handsets are future-proof; old analogue phones are not
• VoIPninjas auto-provisions Yealink and Grandstream handsets — plug in and it works

IP handset vs analogue phone — what's the difference?

An analogue phone connects to the old copper telephone network via a phone socket in the wall. It carries voice as an electrical signal. Simple, but increasingly obsolete — BT is switching off the PSTN in January 2027, and every business in the UK needs a plan.

An IP handset — also called a VoIP desk phone — connects to your router or network switch via an Ethernet cable. It sends voice as data packets over your broadband connection. That means lower call costs, more features, and a phone system that works wherever you have internet.

The physical experience is almost identical. You pick up, dial, and talk. The difference is everything that happens behind the scenes — and the fact that an IP handset will still work in 2030.

What to look for in a VoIP handset

You don't need to become a telephony expert. Focus on these five things.

HD voice (wideband audio)

HD voice makes calls sound noticeably cleaner and more natural. It's the difference between a muffled landline call and a conversation that sounds like the person is in the room. Every handset worth buying in 2025 supports it — but it's worth checking the spec sheet on cheaper models.

PoE — Power over Ethernet

PoE means the phone draws power directly from the network cable. One cable for data and power. No separate plug, no wall adaptor to lose. If your network switch supports PoE (most modern ones do), installation is genuinely plug-and-play.

Colour screen

A colour screen makes it far easier to navigate menus, check call logs, and manage contacts. It's not a luxury feature — it costs almost nothing extra on mid-range models and saves real frustration.

Headset jack

If anyone on your team spends long periods on calls, a headset jack is non-negotiable. It frees up both hands and reduces fatigue. Most mid-range and above handsets include a standard 3.5mm or RJ9 port.

Number of lines

Entry-level phones handle one or two simultaneous calls. Receptionists and busy desks need four to six lines — the ability to put one caller on hold while answering another. Match the spec to the role, not the budget.

Which brands should you consider?

Yealink is the most common VoIP handset brand in the UK SME market — and for good reason. The build quality is solid, the firmware is reliable, and the range covers everything from a basic entry-level phone to a full executive model with a large colour touchscreen. VoIPninjas works directly with Yealink.

Grandstream is a strong alternative, particularly for businesses that want more features at a lower price point. VoIPninjas also supports Grandstream devices with full auto-provisioning.

Snom and Cisco are both reputable options. Snom is popular in Europe and has a loyal following among IT resellers. Cisco is the enterprise standard — excellent hardware, but priced accordingly. For most UK SMEs, Yealink or Grandstream delivers everything you need without the premium.

DECT cordless VoIP handsets

Not every role suits a desk phone. If you run a workshop, a warehouse, a showroom, or a reception area where staff move around, DECT cordless VoIP handsets give you freedom without giving up your phone system.

DECT handsets connect wirelessly to a base station, which itself connects to your VoIP system via Ethernet. Coverage typically extends to 50 metres indoors — enough for most business premises. Staff carry a cordless handset and remain reachable on their extension wherever they are in the building.

IP handset, softphone, or mobile app — which do you need?

This is the most important question to answer before you buy a single piece of hardware.

IP handsets suit reception desks, office desks, and any fixed role where the person spends a significant part of their day on the phone. Physical handsets feel professional and are easier to use under pressure — no fiddling with a laptop app when a customer is waiting.

Softphones are apps that run on a laptop or desktop computer. If most of your team sit at desks with computers, a softphone with a USB headset may be all they need. You save on hardware cost and there's nothing extra to maintain. VoIPninjas works with softphone clients on Windows, Mac, iOS, and Android.

Mobile apps suit field staff, salespeople, and anyone who works away from a desk. They use your VoIP number from a smartphone — calls appear to come from your business number, not a personal mobile.

Most businesses use a mix. Reception and key office desks get IP handsets. Field staff use the mobile app. Laptop-based workers use a softphone. You're not locked into one approach — VoIPninjas supports all three from the same account.

What about your existing phones?

If you've recently invested in analogue handsets and don't want to replace them, an Analogue Telephone Adaptor (ATA) lets you connect them to a VoIP system. An ATA plugs into your router and gives standard phone sockets a VoIP connection. It's a practical short-term option, though you'll eventually want to move to native IP handsets for better call quality and features.

No manual configuration, no IT support required.

If you're not sure which handset suits which role, ask us. We'll recommend the right model for what you actually need rather than upselling on spec you'll never use.

Frequently asked questions

Do I need a special phone for VoIP?

Yes — a standard analogue handset won't work directly with a VoIP system. You need either an IP handset (a desk phone designed for VoIP), a softphone app on your computer or smartphone, or an Analogue Telephone Adaptor (ATA) to connect an existing analogue phone. For most UK businesses setting up a new system, an IP handset or softphone is the cleaner option.

What is the best VoIP handset for a small UK business?

Yealink is the most widely used brand in the UK SME market and a good starting point for most businesses. Entry-level Yealink models (around £40–70) cover basic desk use. Mid-range models (£70–120) add HD voice, colour screens, and PoE. For reception desks handling multiple simultaneous calls, step up to a model with four to six lines. VoIPninjas can advise on specific models once we understand your setup.

Can I keep my existing phone number when switching to VoIP?

Yes. Number porting lets you transfer your existing UK landline or geographic number to VoIPninjas. The process typically takes 5–10 working days and your calls continue uninterrupted throughout. You keep the number customers already know.

Is VoIP affected by the PSTN switch-off in 2027?

VoIP is the solution to the PSTN switch-off, not a casualty of it. When BT retires the old copper telephone network in January 2027, businesses still relying on analogue phone lines will lose service. VoIP runs over broadband — it's already future-proof. Switching now gives you time to get the system right before the deadline, rather than scrambling for a solution in 2026.
