How to Get Two Landline Numbers on One Phone

Have you ever wondered how to get two landline numbers on one phone? For families, freelancers, and small businesses, having separate numbers for personal and professional calls makes life simpler and more organised. The problem is, with traditional landlines this usually meant paying for—and maintaining—a second physical line, which quickly became costly and inconvenient.

But things are changing. By 2027, the UK’s copper landline network is being switched off, meaning every household and business will need to move to digital calling. That’s where VoIP (Voice over Internet Protocol) comes in. With VoIP services like Plexatalk, you can run multiple numbers on a single handset, making call management smarter, more flexible, and far more affordable.

Can You Really Have Two Landline Numbers on One Phone?

With the old copper landline system, the rule was simple: one line, one number. If you wanted an extra number, you had to install and pay for a completely separate line. For families and businesses alike, that meant higher costs, extra hardware, and unnecessary hassle.

VoIP changes the game. Instead of being tied to physical copper, numbers are delivered digitally. This means you can have multiple DIDs (Direct Inward Dialling numbers) all pointing to the same phone, VoIP adapter, or even a smartphone app. In practice, it’s just like having two—or more—landline numbers ringing the same device.

So whether you need a dedicated work number alongside your personal line, or want a family number and a private one, VoIP makes it seamless and affordable.

Why You Might Want Two Numbers on One Phone

There are plenty of reasons why having more than one landline number on the same phone just makes sense:

• Separate business and personal calls – Keep your professional life organised without carrying a second handset or confusing clients with your personal number.
• Freelancers and remote workers – Present a polished, “office” presence while still working from home.
• Families and shared households – Give everyone their own line without needing multiple phones.
• Airbnb or rental properties – Offer a dedicated contact number for guests or tenants without giving away your main line.
• Small businesses – Use one number to establish a local presence, and another to reach national or even international clients.

With traditional landlines, achieving this flexibility was either expensive or impossible. With VoIP, it’s simple—multiple numbers, one phone, no extra hassle.

Why VoIP Is the Smart Choice (and Why You’ll Need It by 2027)

The UK’s Public Switched Telephone Network (PSTN) is being permanently switched off by December 2027. That means the copper landlines we’ve relied on for decades will no longer work—every call will instead travel over the internet using digital voice, also known as VoIP.

So if you’re considering adding multiple landline numbers, it doesn’t make sense to keep paying for outdated line rental. By moving to VoIP now, you’ll not only be ready for the switch-off but also unlock a range of advantages:

• Lower cost – No need for multiple physical lines. Just add the numbers you need.
• More flexibility – Route calls to a desk phone, mobile app, or VoIP adapter, all from the same account.
• Future-proof – Stay ahead of the 2027 cut-off with technology that’s built to last.

VoIP isn’t just a replacement for the landline—it’s an upgrade. With providers like Plexatalk, you can set up two or more numbers on one phone quickly and cost-effectively, knowing you’re ready for the future of calling.

How VoIP Solves the Two-Number Problem

VoIP makes it simple to manage multiple landline numbers without the hassle or cost of extra physical lines. Here’s how it works for different users:

What You’ll Need

Getting set up with two (or more) landline numbers on one phone is easier than you might think. With VoIP, you can mix and match the setup that works best for you:

• VoIP phone – Designed for the job, these handsets support multiple lines and extensions straight out of the box.
• VoIP adapter (ATA) – Prefer to keep your trusty old landline phone? Just plug it into a VoIP adapter and it works with digital calling.
• Mobile or desktop app – Take your landline numbers with you. Run multiple numbers on the same device for calls on the go.

Many households and businesses use a combination—perhaps a VoIP phone in the office, an adapter for the living room handset, and an app on mobile for when you’re out. With Plexatalk, all three can work together seamlessly.
