ISDN Switch-Off

ISDN is being switched off.
But that's actually good news.

BT Openreach is retiring ISDN and PSTN lines. Yes, you have to migrate. But cloud telephony is better, cheaper, and more flexible than anything ISDN ever was. We'll make the transition invisible to your business.

ISDN legacy telephone system infrastructure

The clock is ticking — but don't panic

BT Openreach is retiring all PSTN and ISDN lines across the UK. It's mandatory. ISDN2, ISDN30, analogue lines — all going. But here's the silver lining: cloud telephony is genuinely better. Better features, better reliability, better cost, better flexibility.

Moving early means you have time to plan properly, test thoroughly, and avoid the last-minute rush. Businesses that wait until the final months often pay premium prices for emergency migrations. Smart businesses are moving now.
