Are You Still Using ISDN? Reasons to Switch

In 2020, BT (the largest UK provider of IT Telephony) will be ceasing to take orders from ISDN businesses, before entirely ‘switching off’ the ISDN Network and transferring completely to VoIP technology by 2025. With such a substantial change in communication technology just around the corner, it’s important that business owners take note and begin to take the necessary steps towards the future of business communications. There are many existing problems with ISDN and making the switch now, will save your business time and money and enable you to fully utilize Unified Communications to optimise your online collaboration for the better. 

Initially, change can feel uncomfortable. If you still have reservations about switching your business communications from ISDN to cloud technology, continue reading to see how s3 Communications can transform your business by supporting you through the switch. 

Business Competition 

In 2018, Ofcom reported that there were over “two million businesses in the UK still using ISDN technology”, despite its inconsistent reputation. Therefore, its highly likely that your competitors are still using ISDN and are yet to make the switch to VoIP technology. Getting ahead of your competitors by switching your business communication protocols will give you a huge advantage in faster and more consistent communications between clients and your employees. If a customer can get through to you quickly, with a short wait time, they are far more likely to become repeat customers and choose you over your ISDN using competitors; whose communication is inconsistent, outdated and unreliable. 

Easy Transition and Maintenance 

If the reason you haven’t made the switch yet is because you are worried about the downtime and the effect that it might have on your business and profits, you might be surprised to know how fast and easy it is. s3 Communications can offer combined VoIP technology with your existing PBX hardware where possible, meaning we can simply build on what you already have in place, which acts very similar to an upgrade. This means very little transition is required, enabling your business to make the change rapidly with no negative impact on your company’s profits. 

Switching to Unified Communications also means consistent maintenance. We aim to identify faults before you realise that they are there, fixing them before they become an issue for you. Even so, if you do ever need to contact us, our experienced technicians are on hand 24/7 to immediately take your inquiry and handle it as quickly as possible. This is a service that you just can’t get from ISDN protocols, due to prolonged wait times, engineer costs and call out times. It can take up to 5 days for an engineer to attend a site visit to fix your PBX obstacle, whereas at s3 Communications we work almost entirely through the cloud. This means that we can fix your connection problems remotely through the internet, quickly and causing no long delays for your company communications. 

Flexibility and Expenditure

Utilising Unified Communication platforms means that almost everything is digital and done through the cloud. This means as long as you have an internet connection, you can work from anywhere. Through the use of SIP, video conference calling can be done for free and from anywhere in the world, with as many people involved as you like for no cost whatsoever. This will save your business crucial amounts of expenditure; taking away travel and hotel costs, rented office space needs and lengthy planning and scheduling time. 


Fully embracing SIP and VoIP systems also means that your business can expand its clientele and target service area, as now you will be able to be in full communication with anyone in the world with a simple click of a button. Contact with other countries can be very expensive and something that a lot of businesses are intimidated by, due to delayed, low-quality video calling software and fear of the unknown. With s3 Communications, we can take that fear away. We are on call 24/7 to immediately answer any questions or worries that you may have. We can talk you through the process and teach you how to use the software so that you can be fully confident in embracing international and cloud communications.
