The way businesses make and receive phone calls in the UK is changing.
Traditional analogue landlines have been relied on for decades, but the technology behind them is reaching the end of its life. The UK is now moving towards modern, internet-based telephone services, with businesses using the Openreach network needing to migrate from the old Public Switched Telephone Network (PSTN) by 31 January 2027.
While that may still sound like there is plenty of time, businesses shouldn’t leave the switch until the last minute.
What Is the UK Landline Switch-Off?
The traditional Public Switched Telephone Network (PSTN) is the infrastructure that has supported analogue telephone services across the UK for decades.
However, the network is ageing and becoming increasingly difficult to maintain. The equipment and replacement parts required to keep legacy networks operating are also becoming harder to source.
As a result, traditional services are being replaced by modern digital alternatives that use an internet connection to carry calls.
One of the main technologies businesses will increasingly rely on is Voice over Internet Protocol (VoIP).
What Is VoIP?
VoIP stands for Voice over Internet Protocol.
Rather than sending calls through a traditional analogue telephone line, VoIP allows calls to be made and received using an internet connection.
For businesses, this doesn’t simply mean replacing one type of phone line with another. Moving to VoIP can provide a much more flexible communications system, with features that can include:
- Making and receiving calls from different locations
- Call forwarding and routing
- Voicemail and additional call management features
- Easier addition or removal of users
- Greater flexibility for remote and hybrid working
- Reduced reliance on traditional physical phone lines
The exact features available will depend on the system and provider you choose.
It’s Not Just Your Office Phones
One of the biggest mistakes businesses can make is assuming the landline switch-off only affects their telephone handsets.
Many other systems can still rely on traditional analogue telephone lines.
These could include:
Alarm systems
Some fire, security and intruder alarms may use an analogue telephone line to communicate.
Lift emergency phones
Businesses with lifts should check whether their emergency communication systems rely on the existing telephone network.
Payment terminals
Older card machines and payment systems may still use traditional telephone connections.
Intercom and door entry systems
Some access control and entry systems may also depend on analogue lines.
Fax machines and other equipment
Older fax machines and specialist equipment should also be checked for compatibility with digital services.
Businesses should therefore carry out an audit of their existing infrastructure rather than simply looking at the phones sitting on their desks.
What Should Your Business Check?
If you’re unsure whether your business is ready, now is the time to review your current setup.
Start by identifying every telephone line your business currently pays for and what it is used for. A line that appears unused could still be connected to an alarm, payment terminal, entry system or another piece of equipment.
You should also review your broadband connection. Because VoIP uses your internet connection, having a reliable business broadband service becomes even more important.
Consider how many telephone users your business has, whether employees work remotely or across multiple locations, and what features you need from a new system.
It’s also important to think about resilience. Unlike a traditional analogue phone, digital telephone services generally depend on both an internet connection and power. Your business may therefore need to consider appropriate backup arrangements as part of its continuity planning.
Why You Shouldn’t Wait Until January 2027
It can be tempting to put the switch-off to the bottom of the to-do list, particularly if your current phone system is still working.
But waiting until January 2027 could create unnecessary pressure.
Migrating early gives your business time to identify which systems are affected, compare suitable solutions, replace incompatible equipment and test your new setup before the old service is withdrawn.
For businesses with multiple sites, complex telephone systems or equipment connected to analogue lines, the process may require more planning than expected.
Leaving everything until the deadline could mean trying to make important changes under time pressure — and potentially risking disruption to your communications.
VoIP Is More Than a Replacement for Your Landline
The move to digital telephone services can also be an opportunity to review whether your current communications setup still meets the needs of your business.
A modern VoIP system can make it easier for teams to communicate whether they’re working in the office, remotely or across different locations.
It can also make your telephone system easier to scale as your business changes.
Instead of viewing the landline switch-off simply as another technology deadline, businesses can use it as an opportunity to modernise their communications and prepare for the future.
