The BT 2025 Countdown


BT are switching off the PSTN and ISDN networks for good, starting with a cease of new supply by 2020 and moving to a full migration to IP before 2025. The BT ISDN switch off could affect thousands of businesses in the near future, especially those unaware of BT’s phasing out of ISDN technology.

What does this mean for me?

If you haven’t already heard, BT are switching off the UK’s old copper telephone networks (ISDN & PSTN). This is happening in stages, starting with them no longer supplying new services from
2020 and stopping all ISDN services by 2025.  This change will affect thousands of businesses in the near future, especially those who are unaware of the changes and those businesses whose telephone systems aren’t compatible with internet telephony.

The UK will move all services over to Internet telephony and replace all ISDN & PSTN services with SIP trunks and VOIP services. With the introduction of high-speed Internet access we join the rest of the world and move forward with these newer, cost effective and more flexible internet-based telephone services.

When it comes to SIP & VOIP, customers will not only benefit from lower line rental costs & free direct dial numbers, but they will also benefit from instant diverts & get free calls to all UK landline & mobiles numbers. How much could that save your school?

In Short, by 2020 you will no longer be able to order ISDN services and in real terms you have two options to consider

SIP Telephone Lines (A SIP Trunk)

A Hosted Telephone System (Cloud Telephony)

If you currently have a traditional ISDN/PSTN telephone system then is is good practice to look into an alternative.

Plan ahead and you may actually find you want to migrate sooner rather than later.

Bear in Mind: Businesses will be unable to buy new phone systems that use ISDN and PSTN after 2020 and upgrading your current system to support these technologies is probably going to be a waste of money.

Although the BT ISDN end of life of 2025 has not been set in stone, businesses will be unable to buy systems that use ISDN and PSTN after 2020. If you currently have a traditional ISDN/PSTN based system, now is a good point to look into the alternative. Although there is plenty of time until 2025 rolls around, it’s best to plan ahead and you may actually find you want to migrate sooner rather than later after finding out all of the benefits the replacement ‘IP’ based systems have to offer.

If you’re in the position where you haven’t got a business telephone system yet, you are in the perfect place to start afresh with an IP based telephone solution. This way you can negate any needless expenditure on technology and hardware with a limited shelf life and future proof your small/growing business. BT phasing out ISDN will have no negative effect on you in this case and you may in fact gain a competitive advantage over your other businesses.
