With the big switch-off coming to ISDN phone lines in 2025, all businesses using ISDN phone systems will inevitably be required to make the switch before 2025. As this time is getting closer and closer, you may want to consider making the switch from ISDN phone systems to a more practical communication technology. However, the big switch-off is not the only reason you should be ditching your ISDN phone system. Within this post, we provide a more in-depth explanation of why it is time to ditch your ISDN phone system. We will also be providing some alternatives for communication systems we recommend choosing.  

What is an ISDN phone system?

ISDN stands for Integrated Services Digital Network. An ISDN is a circuit-switched telephone network system that transmits voice, video, data and other network services over the digitalised circuits over a digital line. They are used instead of the traditional circuits of the classic switched telephone network.

What does the 2025 switch-off mean for me?

In 2025, BT will carry out the 'big switch off', meaning that BT will switch off its ISDN phone lines and certain pieces of hardware will stop working entirely. From then on, both businesses and homeowners will be required to use digital phone services. BT has decided to switch off ISDN phone lines because they decided it did not make financial sense to keep making improvements to the ISDN network as they offer little flexibility and IP technology is a better choice to meet future demands.

But you may be thinking “2025 is ages away!”. Yes, but it is closer than you think. As 2025 is getting closer and closer, it’s essential to start planning the switch to an alternative communication system before the panicked rush when the deadline set in.  

Many businesses have already stepped into the future and made the switch to digital phone systems. They're not only ready for the big switch-off in 2025, but they are already enjoying the vast amount of benefits of a cloud-based phone system, such as VoIP technology.

Signs telling you to ditch your ISDN phone system

Starting to plan the switch from ISDN phone systems to a digital phone service early will leave the stress of finding the perfect plan quickly nearer the time when you’re forced to make the switch. Not only does it help ease the pressure later on, but it has a vast range of extraordinary benefits to ditching ISDN phone systems for cloud-based technology. 

You may already be finding that your current ISDN phone system doesn’t work well for your business and is holding you back from evolving your business. Here are a few signs telling you that it’s time to ditch your ISDN phone system for something a bit more modern. 

You want to increase flexibility 

An ISDN phone system requires physical cables to connect, meaning that it is difficult for businesses to make the switch to remote/hybrid working and this makes company expansions more difficult. By moving to cloud-based technology, it drives your business to become more flexible. It allows your workers to work anywhere in the world and not become tied down to one place. ISDN connections are tied to a geographical area and being tied down to one location means that your business is limited on phone numbers and flexibility on where employees work.  

If your business is looking into having multiple office locations and wants to adopt the hybrid/remote working environment, then it may be time to ditch your ISDN phone system.

You want to expand your business

ISDN phone lines are capable of delivering the volume or quality of voice data needed in this increasingly digital world. As ISDN systems require an actual cable to connect the phone system, this means that businesses cannot adapt to working environments that will inevitably be the future, which is hybrid/remote working. 

As of 2020, ISDN users cannot add new lines or amend their current service. Meaning that if your business grows and you need to expand or scale back your telecommunications service, unfortunately, you cannot change your current ISDN service. 

You want to enhance your phone system features and capabilities 

As we have already mentioned, as of 2020, ISDN users cannot amend its features or current service. If you want to add different features and capabilities to your phone systems, then your business will need to make the switch and find alternatives to your current ISDN phone system. IP technology can do everything an ISDN can do and more, yet it doesn't rely on the old systems to work. 

What are the alternatives to ISDN phone systems?

The main choice and best alternative to ISDN phone systems is VoIP technology (Voice over Internet Protocol). VoIP is a term for a call that is made over the internet rather than using a fixed-line communication system. Many businesses have found this type of communication highly useful for efficient and effective internal and external communications. 

VoIP is a more modern and up-to-date communication technology that does not use traditional landlines. All your business will need is a reliable internet connection to make both voice and video calls on a global scale.
