ISDN PSTN Switch-off FAQs – [Guide]

We answer some of the most frequently asked questions about the ISDN and PSTN switch-off.

The switching off of copper telephone lines will see the withdrawal of two different copper-based telephone systems – PSTN and ISDN – and fibre-optic based Internet telephony taking their place. 2025 might seem a long way into the future but five years is not a long time in business – and there are other, more immediate, factors to consider.

Here we answer some of the common questions that customers ask when they are considering their next steps when choosing the best-fit solution for their business needs such as:

  • Is there any push back on any key dates previously referenced due to COVID-19?
  • How do I proceed when I have other services connected to my phone line (Alarms, PDQ Machines, CCTV)?
  • Which products are affected by the ISDN / PSTN switch-off?
  • Can I migrate all of my services in bulk?
