The big BT switch off. What does the end of ISDN mean for your business?

Last year BT announced that by 2025 they will be switching off their PSTN and ISDN networks, migrating them to a single IP core network. As the date draws closer we look at what this means for UK businesses.

What is ISDN?

ISDN (Integrated Services Digital Network) is a set of communication standards for the transmission of voice and data traffic over the traditional circuits of the PSTN (public switched telephone network), and if you’re reading this article, it’s most likely the service used to run your business telephony system.

What does the switch off mean for my business?

In short it means that your traditional telephone system will eventually become obsolete. However, there is no need to worry. There’s still time to migrate to an alternative solution and with the assistance of a dedicated managed service provider, switching from traditional ISDN to an IP based service is simple – especially as companies like Arden Group do all the leg work for you.

What are the alternatives?

The most popular alternative for ISDN is a VoIP (Voice Over IP) solution, which as the name suggests works by transmitting voice data over your existing internet connection.

Over 1.5 million business users have already made the switch from traditional telephony to VoIP as part of their unified communications strategy. The driving force being the myriad of benefits that come with IP based solutions, such as cost savings, scalability, mobility and simple integration.

When do I need to migrate?

Since the announcement ISDN is now viewed as a legacy network, resulting in a lack of investment from providers and therefore making it harder to effectively manage and maintain. Its expected that by 2020 businesses are unlikely to be able to purchase any systems that run off the ISDN network.

The truth is, the sooner you switch to an IP based service, the sooner you can start reaping the benefits such as cost savings, remote access and disaster recovery – see 8 things you need to know about VoIP.
