Is Your Phone System Ready for January 2027?
The PSTN switch-off is happening. If you're still on traditional phone lines, the clock is ticking.
PSTN Switching Off
BT is switching off the analogue phone network in January 2027. All traditional landlines will stop working.
Old System Losing Support
Legacy PBX systems are becoming unsupported. Parts are scarce, engineers are retiring, and costs are rising.
No Remote Working
Traditional phone systems tie employees to desks. No mobile app, no remote working capability.
Paying for Unused Lines
Many businesses pay for ISDN channels and phone lines they don't use. VoIP scales to exactly what you need.
Can't Integrate with Teams
Your phone system should work with Microsoft Teams, not alongside it. Legacy systems can't do this.
Running Out of Time
Engineers will be overbooked as the deadline approaches. Moving now ensures a smooth, properly planned transition.
