The PSTN & ISDN Switch-Off: Is Your Business Ready?
All Copper Phone Lines Will Be Switched Off by 2027
The UK’s traditional Public Switched Telephone Network (PSTN) and ISDN services are being permanently retired by 2027.
This means analogue landlines, older business phone systems, fax machines, alarm lines and many copper-based connections will stop working.
If your business still relies on traditional phone lines, you will need to migrate to a digital, internet-based solution before the deadline.
Businesses that delay risk service disruption, missed customer calls and unnecessary downtime.
For a detailed breakdown of the 2027 deadline and what it means for local organisations, read our Full guide to the PSTN and ISDN switch-off for Somerset businesses.

What is business VoIP?
Business VoIP (Voice over Internet Protocol) is a cloud-based phone system that makes and receives calls using your internet connection instead of traditional landlines.
It provides advanced features such as call routing, auto-attendants and mobile apps, making it ideal for modern businesses across Somerset.
Can I keep my existing business phone number?
In most cases, yes. We can port your existing number(s) to your new VoIP system so your customers continue calling the same contact details without disruption.
Business VoIP FAQs
Is VoIP required for the PSTN & ISDN switch-off?
Yes. With PSTN and ISDN services being retired by 2027, businesses using traditional phone lines must migrate to a digital alternative.
Hosted VoIP is the most common replacement, allowing calls to run securely over your broadband connection.
How long does a VoIP migration take?
Migration times vary depending on your current provider, number porting requirements and system size.
Many Somerset businesses can complete migration within 2 weeks, while some number transfers take longer. We plan the transition to minimise disruption and downtime.
Will VoIP work for remote or hybrid teams?
Yes. Hosted VoIP allows staff to take and make calls from desk phones, desktop apps or mobile devices while keeping a professional business number, making it ideal for hybrid and remote working environments.
Does VoIP require full fibre broadband?
Not necessarily. VoIP works reliably on stable business broadband, including SoGEA and full fibre (FTTP) and Starlink.
The key factors are connection stability, upload capacity and proper network configuration.
Is business VoIP more cost-effective than traditional landlines?
In many cases, yes. VoIP reduces reliance on legacy line rental and allows flexible user scaling.
It also includes advanced features that would typically require additional hardware or add-ons on older systems.
If you're questioning whether your current phone system is limiting performance, flexibility or reliability, read our guide on Signs Your Business Phone System May Be Holding You Back.
What happens if our internet connection goes down?
We can configure resilience options such as call forwarding, mobile failover and secondary routing to ensure inbound calls can still reach your team during connectivity interruptions.
