Modern Communications Road Map

Future-proof Connectivity Road Map

  1. Identify if you’re affected.

  2. Explore your options.

  3. Demystify Voice over IP (VoIP).

  4. Speak to an expert.

The imminent Switch Off of the Public Switched Telephone Network (PSTN) actioned by Openreach offers consumers and businesses alike the opportunity to move away from outdated and restrictive copper-wired telephony, while embracing more secure, cost-effective and modern communications.

By December 2025, customers of ISDN and analogue phone lines will need to consider and implement a cloud-based phone solution, like Voice over Internet Protocol (VoIP), in order to safeguard their service and avoid unnecessary disruption.

What solutions are retiring?

Integrated Services Digital Network (ISDN) Line

An ISDN line is a digital phone line that allows for the transmission of voice, data, and video signals. These phone lines can come as ISDN 2 or ISDN 30. With the upcoming PSTN Switch Off, the ISDN will also be retiring which will make these products obsolete. Businesses that need to issue or utilise multiple dedicated numbers across their business will likely have an ISDN line. If this is you, it may be time to consider a future-proof alternative.

Single Analogue Line

A single analogue line, also known as a traditional phone line, is a legacy communication service that provides one phone number and allows for a single call at a time. With the upcoming PSTN Switch Off, single analogue lines are being retired as part of the transition to All IP solutions. These lines rely on outdated technology and infrastructure, with limited scalability and advanced features.

Multi-Analogue Line

A multi-analogue line allows for one phone number to make and receive multiple simultaneous calls. However, with the upcoming PSTN Switch Off, multi-analogue lines are being retired as part of the transition to All IP solutions. These lines rely on traditional copper-based infrastructure, which will no longer be supported after the Switch Off.
