Your business landline stops working on 31 January 2027.
Openreach is switching off the UK's old copper phone network (the PSTN), and ISDN with it. Openreach has confirmed there will be no further extension. Anything still connected to it stops working on the day, not just phones.
2027
Weeks left to switch
- Keep your existing numbers
- Free review of every line and device
- We handle the move from start to finish
It's not just your phones. Check everything on a phone line.
Many businesses have lines they've forgotten about. Anything on this list that still uses a copper line needs to move before the deadline.
Phone lines and ISDN
Analogue lines, desk phones and older phone systems on ISDN2 or ISDN30.
Broadband on a phone line
ADSL and FTTC broadband that relies on a phone line needs to move to SOGEA or full fibre.
Alarm diallers
Intruder and fire alarms that dial out may need a 4G or IP module from your alarm company.
Card machines
Older payment terminals that use a phone line need to move to broadband or 4G.
Lift phones and door entry
Lift emergency phones and door entry systems often run on their own lines.
Fax and franking
Fax machines and franking machines on a phone line need a digital alternative.
Move to digital calling, and keep your numbers.
GoYap cloud phone system
Calls on desk phones, the GoYap mobile app, the desktop app or a web browser, so your team can answer from anywhere. GoYap phone system.
Keep your analogue phones
In many cases your existing phones can keep working through a router or adapter with phone ports, so nothing changes on the desk.
Keep your phone system
On-site systems such as Avaya IP Office, Mitel and Samsung can connect to us with SIP trunks instead of ISDN.
Calls in Microsoft Teams
Make and take outside calls in Teams, on your existing business numbers. Teams calling options.
Your numbers come with you
Number porting is free for eligible numbers and usually takes 7 to 10 working days. We build and test your new setup first, so there's only a brief pause on the day your numbers move.
Digital calls need the right connection behind them.
Your broadband may need to change too
If your broadband runs over a phone line, we'll move you to SOGEA or full fibre, and can add 4G or 5G backup so calls carry on if the line fails. Business connectivity.
Plan for power cuts
Unlike old copper lines, digital phones need mains power. A small battery backup (UPS) keeps critical lines working, and the GoYap mobile app works over 4G and 5G.
Six things to check before January 2027.

PSTN switch-off questions
When is the PSTN switch-off?
31 January 2027. Openreach has confirmed there will be no further extension. Lines and services still on the old network stop working when it closes.
Can I keep my phone numbers?
Yes. Number porting is free for eligible numbers and usually takes 7 to 10 working days. Keep your current service active until we confirm the move.
Will my existing phones still work?
Often, yes. Analogue phones can usually keep working through a router or adapter with phone ports, and on-site phone systems can connect with SIP trunks. If it makes more sense to upgrade, we'll explain why.
Do I need new broadband?
If your broadband relies on a phone line (ADSL or FTTC), it needs to move to SOGEA or full fibre. We check this as part of your free review.
What about my alarm?
Speak to your alarm company. Many alarms need a 4G or IP module to keep working after the switch-off.
What happens in a power cut?
Digital phones need power, so they stop if your router loses power. A battery backup (UPS) keeps critical lines working, and the GoYap mobile app works over 4G and 5G.
How long does the move take?
It depends on whether your broadband needs to change. Number porting usually takes 7 to 10 working days. The earlier you start, the easier it is to book the dates that suit you.
