The Big ISDN Switch Off

ISDN 1599x920 Banner

Significant changes are coming to the telecommunications industry! BT has announced the closure of the Public Switched Telephone Network (PSTN) by the end of 2026, impacting the ISDN services we currently provide. As a result, Sure will be removing ISDN services from sale starting 30 June 2024, with a goal of migrating all customers by the end of 2025.

While change can be challenging, transitioning to our new fibre-based solutions will greatly benefit your business. You can look forward to improved features, faster speeds, and lower operating costs.

Is your business ready?

We recommend a thorough audit of your network to determine how many ISDN connections you have and of what type. Whatever affected services you have, there are several easy migration paths to ensure that your business is uninterrupted. These include Cloud voice, SIP trunks, and ISDN emulation.

How will it affect you?

The shutdown may affect your organisation in more ways than you think. If you have ISDN services, you will need to migrate them to new digital alternatives. The complete closure will happen in 2026; however, services are gradually being withdrawn from now on, so it is time to plan your migration.

What are the advantages of the new digital services?

The new digital services we offer are not just a replacement for ISDN. They are a significant upgrade. With their high resilience, seamless integration with other products, and faster, more upgradeable features, they offer a much better value. Moreover, they provide you with high-speed connectivity, opening up a world of possibilities with our wider Sure product portfolio, including secure networking, Sure Business Suite, and secure Cloud solutions.

At Sure, we understand the challenges of the ISDN switch off. That's why we're here to help you navigate this transition and reduce your risk as you move to a digital future. Our team of expert consultants is ready to work with you, auditing your existing estate and recommending the most suitable solution based on your unique business requirements.
