PSTN Switch Off

By 2027, all traditional phone lines will stop working and calls will have to be made over the internet.

PSTN Switch Off

The Public Switch Telephone Network (PSTN) will close in 2027. By then, every phone line in the UK will have moved to a fully digital network that uses Internet Protocol (IP) across a fibre-based service. This won’t just affect voice services, it may also mean you need to upgrade your broadband.

What is PSTN Switch Off?

The UK's telephone network is going digital. The Public Switched Telephone Network (PSTN) is scheduled to be switched off in 2027, and your traditional landline connection will be replaced with Voice over Internet Protocol (VoIP) services.

Why is this happening?

The current network is old and difficult to maintain. As an essentially 20th century technology, the PSTN is increasingly out of kilter with the demands of 21st century communications in this digital world.

What is Stop-Sell?

The term "Stop-Sell" is used by Openreach to signify stopping the sale of certain products. This is different from product withdrawn, as under "Stop-Sell" any end customer who already has the product will be able to continue using it (until it is withdrawn).

What is the impact of stop-sell?

Businesses must transition to digital alternatives. Transition can enhance communication efficiency, but at the same time it demands adaption. This will potentially impact operations, compliance and competitiveness. Early readiness is key for businesses.

What else do you need to know?

If you're currently on an ISDN contract, you don't need to do anything at the moment.

However, you do need to be mindful that when your contract is up for renewal, switching to a hosted telephony solution is highly recommended.

What happens in 2027?

The Public Switch Telephone Network (PSTN) will close in 2027. Your provider will migrate all PSTN services to alternative solutions before the December deadline. However, if any of your services remain on the PSTN network they will be withdrawn, and you will be left without service.

What is PSTN and ISDN?

PSTN stands for Public Switched Telephone Network. It's the copper wire network set up for analogue voice communications. ISDN stands for Integrated Services Digital Network, which users the traditional PSTN network to allow the digital transmission of voice, video and other services.

what replacements are available?

VoIP (Voice over Internet Protocol) are the go to solution for replacing traditional systems. These allow you to make calls over the internet and result in better quality calls, smaller bills, a whole host of features and can grow with your business.
