Future-proof your business phones with independent advice.
BT is switching off all PSTN and ISDN landlines. The final cut-off is 31 January 2027, but businesses are advised to switch by December 2025 as the old network becomes less reliable and more expensive.
If your business is still running on traditional lines, you risk higher costs, poor flexibility, and sudden downtime. Cloud Telephony is the modern, cost-effective replacement — and we’ll help you make the switch smoothly.

Why the BT PSTN Switch-Off Matters for Birmingham Businesses
What is the PSTN and ISDN switch-off?
The UK’s old copper-based phone network (PSTN and ISDN) is being retired and replaced with digital IP systems.
Key switch-off dates: December 2025 vs January 2027
December 2025 → Recommended cut-off for businesses to switch, as PSTN services will rapidly degrade.
31 January 2027 → Final nationwide switch-off.
If you leave it too late, you could face higher supplier costs, rushed installations, and downtime.
