ISDN switch off 2025

ISDN is soon to be a thing of the past! Although ISDN lines are still widely used by business across the UK, it was announced by BT in 2015 that the PSTN and ISDN will be switched off in 2025. The purpose of the switch off is to move away from old technologies and replace them with more versatile, cost-effective solutions.

A modern alternative to ISDN

SIP is a public IP telephony service that sets the bar when it comes to business communications. It provides businesses with a more flexible and budget-friendly solution by merging voice and data. What’s more, migrating from ISDN to SIP is simple. Talk to our team to discuss the benefits of SIP trunks in more detail.

“Our recent MyHosted installation by DuoCall went very well. The engineers were brilliant; they were very knowledgeable, the training carried out was to great satisfaction and they were very professional on site.”
