You may have heard from your telco that ISDN and some other voice services are being withdrawn. Over the next five years, the PTSN network across New Zealand is being shut down. This will have a significant impact on your business if you’re dependent on ISDN services.

In 2017, Spark announced they would be migrating off their PSTN (Public Switched Telephone Network) and replacing it with a modern network. In 2018, they announced that a number of ISDN (Integrated Services Digital Network) would be “grandfathered” (still available, but no new additions are able to be sold). Teleconsultants has the details on which ISDN service is going to be withdrawn when.

What this means is that older phone systems (also known as PABX) will need to be upgraded. Some equipment will need to be upgraded to IP devices, some examples are:

  • Fax machines
  • Security systems
  • Fire alarms
  • Vending machines (including refrigerators)
  • Old Sky TV systems

All of this may sound daunting, but the transition from ISDN/PSTN to fibre doesn’t have to be painful and expensive.

So what can you do? Eventually, you will need to upgrade your phone system, either to an off-premise IP-based system or upgrading your on-premise voice system to connect to newer SIP trunks.
