Prepare your Business for the ISDN Switch Off

BT introduced ISDN (Integrated Services Digital Network) in 1986 as a digital means of making phone calls, video calls, and transmitting data over the PSTN.

We live in a digital world, and neither of these technologies can deliver the volume or quality of voice data needed.

In 2015, BT announced they will completely shut off their ISDN and PSTN services by 2025, affecting around 16 million lines and channels, leaving just three more years for businesses to transform their telecoms solutions for business continuity.

The Reason Behind the ISDN Switch Off

ISDN is now outdated against other communications solutions; with broadband internet connection speeds much faster and performing at a higher level, ISDN can no longer compete. Also, with businesses embracing hybrid working, post-pandemic, traditional ISDN lines offer limited flexibility and no longer operate out of one or two locations.

BT decided in 2015 to focus resources on improving up-to-date technology to meet the growing demand for high-speed communication services.

What do businesses need to do to prepare for the ISDN Switch Off?

  1. SIP. Implementing an ISDN to SIP Migration is a good route if you want to keep your current system. You keep all the features of traditional telephony and save up to 50% in operational costs whilst retaining complete control of your communication system. Due to their flexibility, speed, quality and lower costs, SIP Trunks are becoming the most popular alternative to ISDN. Learn more about our SIP Communications Solution here.
  2. Hosted. Switching from ISDN to a cloud communications-based solution requires minimal new equipment and provides you with extensive fixed and mobile capabilities and significant cost savings. If you switch to a hosted solution, you need to consider two things: your internet connection strength and can your existing office phone system support this.
