Why is ISDN being replaced?

Like Lethal Weapon’s Roger Murtaugh, Integrated Services Digital Network systems are preparing to retire. In fact, in this brave new technological age of ours, ISDN is “getting too old for this s#@t!”

After years of speculation, the end is nigh. ISDN dialled its way into existence at the dawn of the internet. This was a different time. The mobile flip phone of yesteryear has firmly flipped shut.

ISDN can no longer compete. This is because the business world has irrevocably changed:

  • Remote and flexible working are the norm
  • Employees use mobile and fixed line telephony
  • IP-based services are commonly used

SIP trunk connection or fully hosted phone systems are now the preferred options of businesses that place communication at the centre of their operation. ISDN is therefore fossilising on the dusty horizon.

ISDN is old and not very functional

Typically delivered on copper wiring, ISDN is vulnerable to threats such as Mother Nature, wiring and interference.

For years, the circuit-switched technology stood tall as the go-to connection for any businesses requiring more than one phone line. Sure, it delivers basic caller ID, direct dial and diverts. When contrasted with internet connected SIP and hosted phone lines though, it falls down faster than a house of cards in a wind tunnel.

Why are businesses moving to SIP and hosted VoIP?

SIP and hosted VoIP solutions are leaving ISDN in the technological rearview mirror. This is because:

  • Location: ISDN phone numbers are limited to the local exchange. SIP and VoIP, on the other hand, mean geography is no longer a factor. In fact, your business can use its phone number from anywhere in the world.
  • Capacity: Remember the days of ISDN? You need to expand capacity and, the only way to do it, is for an engineer to visit. Modern technologies mean once you have the internet connection working, adding or reducing more capacity (or reducing it) can be done pretty much instantaneously.
  • Mobility: Unlike moving home, moving SIP or hosted phone systems isn’t stressful. In fact, it’s easy. This is because they work on IP addresses. This means setting up and moving connections anywhere in the world is simple.
  • Costs: SIP or hosted telephony typically cost less than ISDN whilst giving your business much more.

Will my existing system support SIP?

A good telecoms provider should assess your infrastructure and business needs. This way, a custom solution can be tailored which helps you ring up better business. For those of you on older phone systems, it’s possible that it might not support SIP. In such cases, you’d require an upgrade.
Of course, dependent on your needs, a hosted phone system might be the right solution.
