VoIP to replace ISDN

After nearly 25 years of continuous service, ISDN channels are finally coming to their end of days.

As more and more businesses migrate away from ISDN technologies we explore the reasons for the decline and the replacements on offer to businesses in more detail.

So what is ISDN?

ISDN stands for integrated services digital networks. It is a standard developed to cover a range of mediums like voice, data and image services. ISDN channels were initially intended to provide end-to-end simultaneous handling of voice and data on a single link and network, most if not all businesses would have had one or more of these.

However, as technologies have evolved, these channels have struggled to keep up with the rate of change and often buckle under the pressure.

The decline of the ISDN lines

The number of ISDN channels used by businesses in the UK shrank considerably, with a rate of decline to accelerate as alternative solutions reduce in price and the wide range of application services increase.

We can identify a number of causes behind this decline. For example, the need for remote workers using mobile phones has meant that fewer business people are reliant on legacy phone systems. Other factors, like the greater availability of high-speed internet and the inflated demand for more flexible and collaborative working arrangements, have made IP telephony more attractive.

At the same time as the decline in ISDN connections and therefore market size, there has been a considerable rise in ISDN substitutional IP telephony products such as SIP Trunking and Hosted VoIP solutions. The recent announcement by BT that PSTN is to be withdrawn by 2025 will further generate migration from traditional ISDN2/30 towards these new substitute VoIP products.

The increased desire for flexibility and team collaboration at work is the main course of the ISDN decline. New internet-based telephony systems come with a number of advanced features as standard.

Internet systems like VoIP and SIP trunking can:

  • Shift offices, multiple offices and keep the same geographic number
  • Advanced call routing to multiple destinations or to mobile devices
  • Reduce call costs
  • Video conference aids
  • Team collaboration with call presence and internal messaging

Forward-thinking businesses are not waiting to update their phones. They have already discovered the power of internet telephony and the benefits that they can have on their business.

Replacing your ISDN system

As better broadband becomes more widely available, at lower prices, the case for migrating to an internet-based alternative to ISDN has become more compelling.
