ISDN has been the backbone of business communications for many years. However, the legacy of ISDN is about to come to an end.  It is time to change to future-proof business solutions.


The Last Wave of ISDN


Australian carriers will be phasing out ISDN 2 and ISDN 10/20/30 services over the next five years. With disconnections commencing in June 2019, it is time to transition to future-ready communications.

What is ISDN?

As the original high-speed internet service, ISDN (Integrated Service Digital Network) triggered the development of faster internet during the 1990s. It was a big improvement upon dial-up and was the first technology that allowed businesses to make calls and use the internet simultaneously. The data lines of ISDN were a big advantage as they delivered constant data speeds and provided the flexibility to combine data lines or to use them individually. This was a revolutionary change to the way people did business.

The two main types of ISDN services include Basic Rate Interface (ISDN 2) and Primary Rate Interface (ISDN 10/20/30). The fundamental difference between the two is the level of service they provide. BRI delivers a lower level of performance and is often more suitable for home and small businesses, whereas PRI is intended for larger businesses and enterprise.

ISDN switch off

While ISDN does deliver the basic needs of a business, it can no longer compete against the new and emerging technologies. With faster and cheaper communication solutions entering the market, ISDN is now at the end of its life. Australian carriers will be phasing out all ISDN services over the next five years.


This means you will no longer be able to order any new ISDN services nor receive any more updates on your current ISDN service. Eventually, your ISDN phone and data lines will be cut-off and your business will not be able to operate. Naturally, the cut-off of ISDN has caused distress in many organisations who still rely on this technology.


Timeline for ISDN switch off


  • Jan 2018: End sale for new customers
  • June 2018: End sale for existing customers
  • June 2019: Commence disconnection
  • 2022: Cease support/Final exit

Business communication solutions

It’s in your best interest to begin planning for disconnection now before your ISDN services expire. As an alternative to ISDN 10/20/30, consider MyNetFone SIP Trunking. Not only is it a powerful, scalable and flexible alternative to ISDN, it is also future-ready. SIP trunks remove the need for physical phone lines and reduce the restrictions on call-capacity. When combined with Ethernet, SIP Trunks can support high-quality voice calling and conferencing for up to 200 staff. By using virtual phone lines, SIP Trunks are portable and easy to relocate.


SIP trunks can be deployed with your existing PBX phone system if it is IP compatible, some compatible phone systems include Cisco, Samsung, Panasonic, Skype for Business and more. We will also port your existing ISDN phone numbers so you won’t need to worry about losing your customers. All you really need is an internet connection.


SIP Trunk is a custom solution that allows you to keep using your ISDN PBX. But what if you don’t have a compatible phone system? That’s completely fine, MyNetFone also offers a Virtual PBX phone system where we provide both your phones and communication service, so you won’t even need to break a sweat. The Virtual PBX is an option that will suit smaller businesses or those using a BRI or ISDN 2 service. With numerous handsets to choose from, you will no doubt find a suitable setup for your business.

Business data solutions

The next step after you have decided on your virtual phone system is to get a reliable data service. Both the SIP Trunk and Virtual PBX are dependent on the internet, so if your business requires more than 4 lines, you will need high bandwidth to support your multiple lines. The best data solution for business includes Ethernet broadband and NBN.


Ethernet Broadband

Both Ethernet and NBN give you the option to select data and speeds according to your business needs. Like BRI and PRI, the difference between the two is the level of service they provide. Ethernet offers guaranteed speeds with options of 10mbps – 400 Mbps, which is up to 4 times faster than NBN. MyNetFone Ethernet plans start from just $345.


National Broadband Network 

NBN, on the other hand, is a more cost-effective option for smaller sites that have normal call volumes. However, if you have a call centre or have more than 20 lines, Ethernet is the only viable option. NBN speeds are not guaranteed, we recommend getting NBN 50mpbs or NBN 100mpbs as a minimum for ISDN. The decision really depends on the number of SIP Trunks you require for your business. For more details on NBN speed, please check out our NBN speed guide.
