First of all – what are ISDN and PSTN?

  • ISDN, or Integrated Service Digital Network, has been around since 1986 and is a circuit-switched phone network providing data and voice services via digital lines. Initially, it was considered to be an up-to-the-minute solution which migrated outdated landline technology to the digital arena and allowed for the then fastest web connection at 128kbps. It also meant that data could be sent more speedily than previously, with very few issues from distortion.
  • PSTN, or Public Switch Phone Network, is a traditional analogue solution, sending information via copper lines which are now being phased out.

What advantages does VoIP offer?

Many bigger organisations have already made the transformation this modern, progressive tech, whose benefits include:

  • You can access it with just an internet connection
  • You need fewer phone lines, so there are cost savings to be made
  • When you do need new lines, these can be installed at speed
  • Flexible scalability means that if you have a cloud-based phone solution coupled with a SIP line (this stands for Session Initiation Protocol an is essentially a way of making and ending connections for online voice and data transfers), VoIP means you can easily transfer calls between locations such as different offices while using the same line wherever you are in the country.
  • You’ll be able to see which team members are free to take or make calls


Preparing for the big switch-off

As we mentioned, analogue solutions ISDN and PSTN are to become redundant by 2025. And while you still have a few years in hand, it makes sense to prepare for the changeover now.

Particularly, for example, if your phone contract is due to be renewed, now is a good time to make the switch and begin looking into VoIP alternatives, which will allow you to manage your phone solution via a cloud-hosted online control panel.

What you need to do

  • Do a thorough audit of your business needs
  • Talk to communications specialists about available options
  • Make sure you have the bandwidth for the VoIP solution as well as all the other things your business uses the internet for – the last thing you want is a patchy service or poor-quality audio
