How prepared are you?
The clock is ticking on the 2025 PSTN Switch Off… Futureproof your business now.
By December 2025, UK analogue PSTN services will be switched off. The PSTN is the national infrastructure that underpins traditional phonelines, ISDN, and ADSL2. Unless you have moved to an all-IP approach, your internet will be switched off, phones will be silenced, and your security alarms will no longer operate. Act now to get your business up to speed.

FAQs
-
Why is the PSTN switch off happening?
Openreach are discontinuing their legacy PSTN network to focus on new and improved modern fibre technology.
-
What does stop sale mean?
At the time of stop sale, you will no longer be able to renew your contract for the traditional PSTN network based services. Additionally, you will no longer be able to order any new services (new phonelines etc.) to your service.
-
How do I know when my area will reach the stop sale and stop service phase?
Openreach have provided a list of their stop sell exchange sites and when these will be happening, here.
-
What services will be affected?
Basically, anything currently using a copper line. In addition to the typical phone and broadband services you initially think of, services such as cctv, alarms, lift lines, door entry systems, fax machines, and card machines will all be affected by the PSTN switch off. Any services that currently use a phone line to work will need to be moved away from the PSTN network ahead of the switch off.
-
Can I keep my current phone system?
Yes, but this requires your current PBX (private telephone system) to be SIP compatible, which can often require costly hardware and licensing upgrades. As an alternative, you could look to migrate to a hosted voice or Microsoft Teams based solution. If your current PBX is SIP ready, or you are looking to migrate to a hosted system, get in touch with Claranet today for us to begin to support you in this transfer.
-
What are the alternatives to the PSTN network?
The following technologies replacing PSTN are being implemented by Openreach:
- FTTP (fibre to the premise): Providing broadband and internet solutions directly to the property.
- SOGEA: Fibre to the cabinet (FTTC), followed by SOGEA to the property. SOGEA will use the existing copper line but without the analogue capability, and it will become an IP only connectivity line.
-
Why is it better to move over to an all IP approach such as VOIP?
VOIP offers many more features and at an individual user level is often much cheaper than a traditional PSTN offering. On top of the additional features, you also have better resiliency and control over disaster recovery, enabling your business to offer the level of service your customers expect.
-
What is FTTP?
FTTP is fibre to the premises, meaning that you have a full fibre connection from the local exchange straight to your home. This provides a much faster connectivity compared to the old copper network and is the ideal alternative to the PSTN.
-
What happens if there isn’t FTTP in my area yet?
When FTTP is not yet available in your area, you can be moved onto the SOGEA network instead. This is a line connection which is for broadband use only. Openreach have confirmed that they will be continually adding to and updating the fibre network and it is expected that FTTP will continue to be rolled out to premises.
-
If I move to VoIP, will I have to change my phone number?
No, you can migrate your phone number. Claranet can port your number onto the all-IP approach for you.
-
Stop service isn’t until 2025, why do I need to act now?
The PSTN service is happening. By acting now, you can futureproof your business, increase business flexibility, and reduce costs. Migrating your services, updating the offices, and replacing the phone system requires time to build a robust plan. Claranet can do the hard work for you, providing you with a modern and bespoke service customized for your specific business needs.
-
My lifts, alarms, and CCTV are all via the PSTN network. Who do I speak to to get these migrated?
Claranet can work with you to replace the traditional PSTN lines that supply these services. However, the provider of this technology will be able to guide you further on how they plan to transfer their equipment to the new all-IP approach.
-
Will my business still be operational while Claranet migrates everything to an all-IP approach?
Claranet will work with you to migrate your services, ensuring that there is minimal impact to your business.
