Are you ready for the switch off?

By the end of 2025, PSTN and ISDN telephony will no longer be available in the UK. But don’t worry, there’s a more cost-effective, scalable, and implementable solution. There’s VoIP, which enables businesses to conduct quality calling using an internet connection, and much more. 

IT support providers in York can help your business to seamless setup and implement VoIP telephony, enabling your business to enjoy the benefits of this technology well ahead of the switch-off. 

There's a better way

The Problem With ISDN and PSTN

ISDN and PSTN laid an invaluable foundation for connectivity and telephony, but with them coming out of use by the end of 2025, it’s time for businesses to untangle themselves from cabled connections, and instead tap into the future, with a telephony solution that is less costly, more scalable, and packed with new capabilities. 

Aside from the incoming switch off, here’s why it’s better to make the switch to VoIP sooner rather than later. 

Lower Quality

Calling quality with ISDN and PSTN can often be patchy and less reliable than modern solutions.

Less Scalable

Scaling your telephony with the growth of your business is costlier and more complex with ISDN and PSTN.

Limited Features

ISDN and PSTN-based solutions are harder to integrate with your digital tools and workflows.

Complex and Costly

ISDN and PSTN is harder to manage and is costlier to maintain, upgrade and repair.

The Benefits of VoIP


VoIP requires minimal investment in hardware and infrastructure to implement. All it takes is an internet connection, a smart device, and a VoIP application.

Highly Scalable

Add new lines and users at the push of a button, and evolve your telephony services to meet the needs of your business and the people it serves. 


VoIP can be used from any smart device and location with an internet connection, making it remote-work friendly. As a cloud-solution, configuring and managing your telephony infrastructure becomes easier and less costly. 


Tap into features like voicemail to email, integrate VoIP with digital channels like your CRM, and create fail-safe mechanisms that redirect calls to available lines for a superior operational and customer experience.
