Analogue PSTN phones to be replaced by VoIP in 2025

The PSTN (Public Switched Telephone Network) is the analogue copper cable phone network that has been used in the UK since 1876. Back then, even transatlantic telegraphs operated via copper cables under the ocean – all well-and-good until they needed fixing.

By the 1930s, it was common for affluent households to have a telephone in their home, and more jumped on the bandwagon in the 60s when the answer machine was introduced, and then in the 80s when the cordless handset was invented.  As we headed into the 2000s, it was outrageous to announce that you didn’t have a landline in your own home. But are home phones on their way out?

In 2025, it’s reported that ageing telephone cables will be replaced by fibre ones, and phones will receive digital signals instead of analogue – it’s called the PTSN switch off. As a copper-line handset will not connect to the outside world without an adaptor in this case, homes and businesses will need to find an alternative to their traditional landline systems before 2025.

And that alternative is VoIP. Invented in the late 90s, VoIP software allows people to use their internet connection to make telephone calls from anywhere in the world, making this the most practical option for users to switch to as we approach 2025.

What other equipment will be affected in 2025?

In this day and age,  it’s a common resource for people to use their mobile phone if they are stuck in a lift. As phone lifts are operated by ISDN lines, these will also be switched off in 2025 so alternative emergency lift phones need to be wifi-friendly. Payment terminals, CCTV and door entry systems that are dependent on copper wires to send money or security alerts will also need some adjustments to prepare for the dates that the telephone networks are being switched off by British Telecoms.
