If you’ve heard the term VoIP floating around but aren’t entirely sure what it means, or whether it matters for your business, you’re not alone. Most small business owners encounter the phrase when they’re looking at new phone systems or when someone mentions the upcoming PSTN switch-off. The good news is that VoIP is straightforward once you strip away the jargon, and it could save your business a significant amount of money.
What Does VoIP Stand For?
VoIP stands for Voice over Internet Protocol. In plain English, it means making and receiving phone calls over the internet rather than a traditional copper phone line. Instead of your voice travelling through a physical telephone network, it’s converted into digital data packets and sent across your broadband or leased line connection.
Think of it like the difference between posting a letter and sending an email. Both get the message across, but one uses a physical delivery network and the other uses the internet. VoIP is the email equivalent for phone calls.
A VoIP phone service typically includes:
- A cloud-based phone system (also called a hosted PBX) that manages your calls
- IP handsets, softphone apps, or a combination of both
- Your existing broadband or leased line connection
- A VoIP service provider who manages the infrastructure and gives you your phone numbers
VoIP vs Traditional Phone Lines: What’s the Difference?
Traditional phone lines, known as PSTN (Public Switched Telephone Network) or ISDN lines, rely on physical copper infrastructure. They’ve served businesses well for decades, but they’re expensive to maintain, inflexible, and are being switched off across the UK by January 2027. Find out more here.
VoIP phone services, by contrast, run entirely over your internet connection. This means:
- No expensive line rental for multiple physical lines
- Easy to scale: add or remove users in minutes
- Works anywhere with an internet connection, including remote and hybrid workers
- Advanced features included as standard, such as call recording, hunt groups, voicemail-to-email, and auto-attendants
- Lower call costs, especially for international calls
Is VoIP Right for Small Businesses?
Absolutely. In fact, a VoIP phone service for small business is often a far better fit than traditional telephony. Here’s why:
Cost savings: Line rental for ISDN or PSTN lines adds up quickly. With VoIP, you typically pay a low monthly fee per user rather than per line, and there’s no costly hardware to maintain on-site.
Flexibility: Whether your team works from the office, home, or a mix of both, they can use the same business number and access the same features from any device.
Professionalism: Small businesses can present themselves with the same telephony features as large enterprises, auto-attendants, hold music, call queues, and more.
Scalability: If your business grows, adding new users to a VoIP system is simple and quick. No engineer visit required.
Choosing a VoIP Service Provider in the UK
Not all VoIP service providers are equal. When evaluating your options, look for:
- UK-based support: this is important if something goes wrong
- Uptime guarantees and redundancy: your phone system is business-critical
- Handset and softphone options that suit your team’s working style
- Integration with tools you already use, such as Microsoft Teams or your CRM
- Transparent pricing with no hidden costs
It’s also worth checking whether your provider offers a managed VoIP service. With a managed service, a specialist team handles the setup, monitoring, and ongoing maintenance of your phone system, freeing you up to focus on running your business.
