VoIP vs Landline for Business

Choosing a phone system for your small business may not be the most exciting job in the world, but it’s more important than you might think. Reliable communication is the backbone of most companies, whether you're taking customer calls, checking in with your team or negotiating with suppliers.

If you're wondering whether to stick with your traditional landline or switch to a modern VoIP system, this guide is for you. We’ll break it all down in plain English, compare VoIP vs landline, and help you decide what’s best for your setup.

What Is VoIP, and How Does It Differ From a Landline?

VoIP stands for Voice over Internet Protocol. With this technology, phone calls are made over the internet instead of through the copper wires used by a traditional landline. So, is VoIP a landline? Not quite. It performs the same function, but it’s powered by your business broadband.

With VoIP, you can use the same phone number across different devices, including mobile phones, laptops, and desktop phones. This makes it a lot more flexible for small businesses on the move or with team members working remotely.

Is VoIP Cheaper Than a Landline?

VoIP is generally less expensive than a landline, especially if you're already paying for broadband (and let’s be honest, most of us are). VoIP calls, particularly international ones, can be much more affordable. Some VoIP plans even offer unlimited calls or pay-as-you-go options.

Landlines, on the other hand, often charge extra for international calls, and these costs can quickly add up. It’s worth bearing in mind that traditional copper phone lines are being phased out gradually. In the UK, the digital switchover is set for 2027. Switching to VoIP now means you're staying ahead of the curve and investing in a solution that’s ready for a digital future.

Is VoIP Good For Remote Work?

One of the biggest VoIP vs landline debates comes down to flexibility. If your team is spread out, working from home or travelling regularly, VoIP gives them the ability to take a phone number anywhere there’s an internet connection.

With VoIP, your office number can ring on your mobile device, laptop, or desktop app. On the other hand, landlines are fixed in place, so if you’re out of the office, you’re out of luck.

Are Landlines or VoIP More Reliable?

Landlines win when it comes to consistent call quality, since they aren’t affected by broadband speed or Wi-Fi dropouts.

But is VoIP better than a landline when your business broadband is reliable? In most cases, yes.

Can You Add New Lines With VoIP?

Need to scale up quickly? VoIP systems allow you to add new lines with just a few clicks, eliminating the need to call an engineer, which is great news if your team’s growing or you’re moving premises.

Landlines, while still scalable, usually involve more logistical challenges, such as physical line installations, new hardware and labour costs.

Do Power Cuts Affect VoIP?

The key downside to VoIP is that it is entirely reliant on an electricity supply and an internet connection. So if your power or broadband goes down, so does your phone system. That said, some VoIP providers do offer workarounds, such as re-routing calls to your mobile device during outages.

Landlines usually don’t require electricity to operate, making them more reliable during emergencies, which is why many SMEs maintain one as a backup.

VoIP vs Landline Features

Here’s where VoIP really shines. It’s not just about making and receiving calls.

Most VoIP systems come packed with extras like:

• Voicemail to email transcription

• Call forwarding and smart call queues

• Video conference calling

• Call recording

• Integration with CRM platforms like Salesforce

Traditional landlines simply don’t offer this kind of technology.

Is VoIP Right for Your Business?

So, when it comes to VoIP vs landline for business, what’s the verdict? VoIP makes most sense for small businesses if:

1. You have reliable business broadband

2. You have remote or flexible workers

3. You would benefit from extra features

4. You’re looking to cut costs

That said, if your internet connection is patchy or you need guaranteed phone access in the case of a power cut, a landline still has its value at present. It may be worth getting ahead of the game and exploring a more reliable broadband service before the digital switchover renders traditional landlines obsolete.
