Time is running out for the ISDN Switch Off

Time is running out for the ISDN Switch Off

In Short

Time is running out with declining services and support, why leave the changeover to 2025?

With every day that passes, the ISDN Switch Off is looming imminently.  With increasing areas on stop sell and declining stock and support, the need for businesses to embrace the switch off and consider how their telecommunications need to change is becoming more urgent.


The “Switch On to the Switch Off Survey 2021” indicated that 83% of organisations had no visibility of when their services would be switched off and 77% said they have not prepared for any disruption that the switch off of these services may cause.


Covid certainly hasn’t helped the situation with businesses prevented from implementing new telecommunications solutions to prepare for the ISDN Switch Off. Not only that, but the pandemic brought the need to accelerate digital transformation bringing extra pressures on budget and demands for flexible working.


The Cloud Industry Forum suggested that 70% of the workforce are now working at least 1 day a week remotely, meaning a significant increase on video and unified communications for businesses.


Business in the News questioned 100 UK Business Leaders and it revealed that 50% of them had no idea that their existing phone and ISDN services will be switched off. In fact it is apparent that thousands of businesses that are unaware of BT’s phasing out of ISDN technology will ultimately be left without service from 2025 if they fail to switch to an alternative telecoms system.

So what can I do about choosing a new solution?


From 2025 all calls will be made over the internet meaning that all traditional phone lines connected to broadband will be affected; as a result, all calls will be determined by the strength of internet connection.


So, a new phone system will need to be robust, with a high-quality internet connection, whether it is fixed or mobile but either way it will be a top priority for businesses to implement in time, investing in a new IP voice solution to avoid delays and frustrations; any poor connectivity will have a massive impact on businesses’ communications and productivity.


When exploring other alternatives, businesses should review their needs and requirements and how they may change in the future before even exploring the advantages and disadvantages of any new solution.


Adopting IP and VoIP provides greater scalability and flexibility for now and the future with firms often opting to migrate to fibre based broadband services to have access to greater speed and bandwidth.


SIP Trunking gains businesses a higher level of control and can reduce costs as you are able to maintain existing PBX equipment through the use of an analogue adaptor or SIP gateway. Alternatively using a hosted phone system offers simple installation, minimal on-site equipment needed and no maintenance issues.


Both offer scope for scalability and customisation for business to make the transition before ISDN is switched off.


Businesses won’t necessarily need to replace all their handsets and services, as these may well have the ability to cope with your new phone systems, however, when changing over, you may want to consider the type of hardware your teams need.  As a result of flexible, remote working, softphones have increased in popularity, reducing the number of handsets required.


It is fair to say that the cut off date is 2025 is when all ISDN lines will be redundant, but businesses must remember that with each passing month, BT are increasing the areas on stop-sell and the decline in services means the need to address and embrace future technology in plenty of time rather than leaving it too late.
