Do you know about the ISDN Switch OFF? Here’s what you need to know

ISDN (Integrated Services Digital Network) is a system that allows voice and data to be transmitted over digital lines. This system has been in use for decades, but it is now being upgraded, with the legacy network switch off due to happen in 2025.

So, why is the ISDN switch off happening? The main reason is that the technology is becoming outdated. With the rise of more modern digital technologies such as SIP (Session Initiation Protocol) and VoIP (Voice over Internet Protocol), ISDN is no longer the most efficient or cost-effective option. Additionally, the switch off will free up resources for newer and more advanced telecommunications technologies.

How will it Affect your Business?

The ISDN switch off will have a significant impact on businesses that currently use the technology for their voice and data communications. If your business still relies on ISDN, it is essential that you start preparing for the switch off now. This will involve upgrading your telecommunications infrastructure and moving to more modern systems. To delay the upgrades to our own telephony solutions may even result in a degrade in performance or call quality as the deadline draws closer.

Upgrading to SIP/VoIP

One of the main benefits of upgrading to SIP or VoIP is that they offer greater flexibility and scalability. This means that your business can easily add or remove lines as needed, without the need for costly and time-consuming installation work. These technologies are also more cost-effective in the long term, as they are based on internet connectivity rather than dedicated digital lines.

In addition to upgrading your telecommunications infrastructure, it’s important to consider other factors that may be affected by the switch off. For example, you may need to update your telephone systems and train your staff on how to use the new technology. Is your network fit for purpose as more demand for cloud services is ever increasing? It’s worth reviewing your existing bandwidth, router, and firewall.

You should also consider whether you need to change your business processes to take advantage of the new features and capabilities offered by SIP and VoIP.
