When choosing the right phone system for your business, the decision between VoIP and traditional landlines is more relevant than ever. With the shift towards digital communication and the planned switch-off of the UK’s copper landline network in 2027, now is the perfect time to evaluate which option works best for your business needs.
At TinCan Comms, we specialise in business telecoms, offering tailored solutions to keep your business connected and future-proof. In this guide, we’ll explore what VoIP and landlines are, compare their benefits, and help you make an informed choice.
What is VoIP?
VoIP stands for Voice over Internet Protocol. Instead of using traditional copper wires to make phone calls, VoIP systems transmit voice data over the Internet. If you’ve ever used Zoom, Microsoft Teams, or WhatsApp calls, you’ve already experienced VoIP.
VoIP systems convert your voice into digital packets and send them over your broadband connection. These systems typically have a user-friendly online dashboard and can be integrated with mobile devices, desktops, and business tools like CRM systems.
What is a Landline?
Traditional landlines use the Public Switched Telephone Network (PSTN) to carry analogue signals through physical copper wires. While once the gold standard for voice communication, landlines are now considered legacy technology. The UK is phasing out the PSTN by January 2027, affecting all standard landline connections.
If your business still relies on landline services, it’s time to start planning for a transition.
Key Differences Between VoIP and Landline
| Feature | VoIP | Landline |
| Connection | Internet-based | Copper wires / PSTN |
| Setup & Hardware | Minimal – can use existing devices | Requires physical phone lines |
| Call Quality | Excellent (with stable internet) | Consistent but outdated infrastructure |
| Scalability | Highly scalable and flexible | Limited by physical infrastructure |
| Cost | Lower call costs and maintenance | Higher ongoing costs |
| Features | Rich features (call forwarding, video, etc.) | Basic call functionality |
| Future-proofing | Ready for the 2025 PSTN switch-off | Obsolete after 2025 |
Benefits of VoIP for Businesses
1. Cost-Effective Communication
VoIP systems offer significant cost savings, especially for long-distance or international business calls. Since VoIP uses your existing internet connection, you avoid line rental fees and expensive call charges typical of landlines.
2. Flexibility and Remote Work
With more businesses adopting hybrid or remote working, VoIP allows your team to take calls from anywhere. Whether your employees are in the office or working remotely from home, VoIP ensures they stay connected using mobile apps or desktop software.
3. Scalability for Growing Teams
VoIP systems grow with your business. Adding a new user is as simple as creating a new account – no need to install new phone lines. This flexibility is ideal for SMEs and larger enterprises.
4. Advanced Features
VoIP systems come packed with productivity tools:
- Voicemail-to-email
- Call forwarding and routing
- Call recording
- Conference calling
- Integration with CRM and helpdesk systems
These features help improve customer service and streamline internal communication.
5. Future-Proofing Your Business
With the PSTN switch-off approaching in 2027, businesses still relying on landlines must act soon. VoIP is not only the modern alternative – it’s the necessary one.
At TinCan Comms, we help businesses migrate from outdated landlines to modern VoIP solutions with minimal disruption.
Are There Any Downsides to VoIP?
Like any technology, VoIP has some considerations:
- Internet Reliability: VoIP depends on your internet connection. If your broadband is unstable, it can affect call quality. However, with the UK’s expanding fibre infrastructure, this is less of a concern than it once was.
- Power Dependency: VoIP systems require electricity so you could lose access in the event of a power outage. Battery backups and mobile failover options can mitigate this.
Overall, these challenges are manageable with proper planning and support from an experienced telecoms provider.
