ISDN switch-off is driving the journey to cloud

The ISDN switch-off is coming. Will you be ready in time?

For those of us that work in technology, the shift to cloud telephony is a clear no-brainer. Ultimately, it’s just IT application running on the network, which means that it offers much simpler automated management, deployment and provisioning. Industry experts agree – according to recent research by Transparency Market Research, the cloud telephony service market is expected to grow at a CAGR of 17.2% From 2018 to 2026.

However, end-users don’t always think in the same terms. Often, they need a push, as well as a pull of multi-benefits, to adopt a new technology. This is certainly happening in telephony with the phasing out of Integrated Services Digital Network (ISDN) lines by telecom operators.

In 2015 BT announced its intention to switch off its PSTN and ISDN networks by 2025. As we approach this date, we are already seeing industry abandonment of legacy technology, such as large PBX vendors withdrawing support for on-premise hardware product lines, and many organisations are beginning their ISDN to IP conversion strategies.

As a sector we are undergoing a fundamental change with the shift from ISDN to SIP trunks. Of course, there are still many organisations that are keeping their on-premise telecoms platforms, but the switchover is certainly prompting a marked adoption of cloud hosted telephony solutions.

Cloud computing has changed the world of technology forever – gone is the hardware heavy business; we are now living in a software world where only few of us can remember the pain of back-up tapes and floppy disks to transfer and store information. Just as cloud computing has changed the world of data, it is now doing the same with voice. The cloud makes it possible to streamline delivery of data and voice and crucially enable organisations to have what they really want – one supplier for their voice and data.

Technically speaking, all forms of communication will be digitally transformed by the change to the all IP standard. At the same time, all IP provides the foundation for new cloud services, which will facilitate a new world of work. With all the benefits, which span cost and efficiency savings, the adoption of cloud telephony becomes very much of a case of “when not if” – as we need the ISDN switch-off we can certainly expect a huge spike in adoption as organisations see the light and switch across.
