“The End of the Line”: ISDN Will Be Gone by 2025


    Integrated Services Digital Network (ISDN) is to be phased out by 2025 according to the BT Group CEO, Gavin Patterson, who made the announcement back in 2015. However, not all businesses are fully aware of the impact this may have on their future operation. So, what exactly does the death of ISDN/PSTN implicate for the future of telephone systems technology?

    How May This Impact Your Business?

    If you haven’t already been prompted to switch over from ISDN at the time of this announcement, you should be thinking about plans to facilitate this before 2025. All businesses need to make this transition within the remaining time frame. However, last year in 2017, it was estimated that around 3 million lines were still using BT’s ISDN platforms, which will need to change sooner rather than later. There is concern about whether everyone will be able to migrate to the other technology in this short time. By 2025, all businesses should be using VoIP (Voice over Internet Protocol) telephony.

    What Is The Future of Telephone System Technology?

    As telephone systems move away from the old-fashioned technology and into the digital world, you may be considering how this signifies developments in the telephone system industry and its technology. BT Group envisions that the future of their telephone systems will consist of a singular, core IP network. This technology will replace analogue and ISDN telephone system technology.

    What Can Your Business Do?

    What options does your business have if they are using ISDN and need to migrate to VoIP?

    1: On-Premise System
    You could use an On-Premise telephone system, which is the less expensive option. These connect to SIP trunks and use VoIP technology, however the actual telephone system is located on the premises of the business. These can be purchased in full or financed, and are more cost-effective and flexible than ISDN systems. Regardless of the planned reforms to telephone systems by 2025, from a money-saving perspective, it also makes sense to switch over to SIP from ISDN.

    2: Hosted Telephony System
    Another option is Hosted Telephony systems, that are Cloud-based. The actual telephone systems are located in data centres and lots of businesses will share the resources. These are paid for on a monthly basis, per phone.

    Benefits of VoIP vs ISDN

    • Since VoIP uses an Internet connection to receive calls, as opposed to traditional analogue phone lines, with a fast Internet connection this can improve the quality and efficiency of your service
    • Money saved on line rental and call costs – the savings can be very significant.
    • Flexibility in regards to location, inclusive minutes and numbering.

    You should make sure that your business is fully prepared to move away from ISDN technology as soon as possible, so that you’re way ahead of the game when it comes to 2025. It’s not much longer before the planned phase-out will be initiated, so it is best to be prepared. Aside from the scheduled telephone system changes, there are plenty of other reasons to consider VoIP for your business telephone system, as explored above. These are all factors to bare in mind when making your decision.
