Croft is taking a different approach to the PSTN Switch Off compared to many telecoms companies. We're not here to scare you into buying an alternative solution now, that won't be right for you in the future. We'll help you migrate to future proof technology...without the fear.
The Public Switched Telephone Network (PSTN) will reach the end of it’s life in January 2027 and we're here to help you navigate the switch off.
Any Single Analogue Lines, Multi-Lines, ISDN2 and ISDN30 services will need to move to alternatives, prior to this date.
The Great Switch Off will impact broadband customers as well. ADSL and FTTC broadband services supported by Single Analogue Lines will need to migrate to a new service.
We’re here to work with you, understand your requirements, and help you choose a future-proof solution.
This is how we support you in the migration away from PSTN.

DownloadWhen does the Great Switch Off start?
It’s already started. As of the 5th September 2023, BT Open reach initiated the first phase of the PSTN Switch-off with the national stop-sell of the Public Switched Telephone Network (PSTN). This means that BT Openreach are no longer offering new PSTN-based services. It’s important to understand that you can continue using pre-existing legacy PSTN services until the complete Switch Off in January 2027. However, during this period, you will not be able to purchase any new services or modify any existing services that rely on ISDN or PSTN.
When is the final Switch Off happening?
BT Openreach has announced it intends to Switch Off the traditional, analogue telephone network in January 2027.
When should businesses switch their services from the PSTN?
Businesses should start preparing for the PSTN Switch Off now, to ensure smooth transition to the new technologies outlined in this guide. Failing to prepare for this transition can result in disruptions to business operations.
Will the Switch Off affect my internet connection?
If you are still using ADSL, ADSL2+* or have a FTTC internet connection that runs over an analogue PSTN telephone line then you will need to upgrade your internet connection. If you’re not sure what services you have please contact us.
What does the Great Switch Off mean for my business?
The Great Switch Off will affect all businesses currently operating using PSTN and ISDN services. If you fall into this category, you will need to move to the new voice and connectivity solutions, outlined in this guide, well before the January 2027 deadline to keep your communication and connectivity services operational.
How will the 2027 Switch Off impact devices connected to the PSTN?
ALL technology that uses the PSTN network will be impacted. The transition will affect services such as security and fire alarms, telecare devices, and retail payment terminals and any other devices that rely on the PSTN. If you are unsure about how a device in your business might be affected, we recommend you contact the equipment supplier or device manufacturer to find out whether it will remain functional on a digital phone Line. If you are buying a new alarm or device, you should check it is compatible with Hosted (VoIP) services.
Can I keep my existing number when migrating to a new service?
You can keep your existing phone number if you inform us at point of sale/when you place your migration order. You will need to take out a Voice service (to run parallel with your Connectivity product) and indicate that you wish to port the number onto the new Voice service, otherwise you will Lose the number once the service migrates away from the existing service.
