What is the 2027 landline switch-off?
The UK’s Public Switched Telephone Network (PSTN) is set to be completely switched off by 2027. This means that traditional landline services, including ISDN and analogue phone systems, will no longer function. Businesses must transition to digital alternatives such as VoIP (Voice over Internet Protocol), virtual landline services, and cloud-based telephony to maintain seamless communication. A virtual phone system can replicate everything a traditional landline does — local numbers, call routing, voicemail — but runs entirely over the internet at a fraction of the cost.
Why is PSTN being phased out?
The PSTN network is outdated and costly to maintain. As digital communication technology has advanced, the need for a more reliable, flexible, and scalable solution has grown. Switching to internet-based telephony offers businesses improved call quality, enhanced features, and lower operational costs.
What does this mean for your business?
If your business still relies on traditional landlines, you will need to migrate to a digital telephony solution before the 2027 deadline. Key considerations include:
- t
- Upgrading phone systems to support VoIP technology.
- Assessing internet connectivity to ensure sufficient bandwidth for digital communication.
- Reviewing existing contracts to plan a seamless transition without disruptions.
- Training employees on the new system for a smooth adoption.
