Prepare for the Big Switch Off 2027
Is your business ready for the PSTN Switch Off?
The UK's traditional Public Switched Telephone Network (PSTN) is being retired, with BT planning to retire the PSTN by 31 January 2027. The move will transition businesses and consumers away from traditional analogue landlines towards modern digital communications services.
For businesses still relying on traditional phone lines, the switch off is an important opportunity to review their existing telephone setup and move to a future-ready solution.
Instead of waiting until your existing service is affected, you can move your business number to a cloud-based business phone service and continue making and receiving calls using modern VoIP technology.
Moving to a digital phone solution can give your business:
- A replacement for your traditional phone line
- The ability to keep your existing business telephone number
- Calls over an internet connection
- Greater flexibility over where calls are answered
- Access to additional call management features
- A scalable solution as your business grows
Don't wait until the PSTN Switch Off affects your business. Our team can help you understand your options and find the right replacement for your existing business phone line.
