Change is coming

Your telco such as Telstra may have contacted your business about how the way our Internet and telephony connection is going to change soon. With the NBN business grade rollout, that change involves ISDN vs SIP – and here’s what you need to know about it right now.


As it currently stands, unless your business has already made the switch to the NBN – the rollout would have happened in your area and you would have been informed – you may still have ISDN and may know little about SIP. The latter is the way forward and you may be delighted to learn it can really help your business.

Here’s what you need to know:

  • The major telcos, such as Telstra, have announced they have stopped the sale of ISDN2, ISDN2 Enhanced, ISDN10/20/30, DDS Fastway, Megalink and Frame Relay products due to the supporting technologies and platforms nearing the end of their life.
  • By 2022, those who already have these products and the underlying technologies and platforms that support them will have ceased being supported by the relevant vendors, meaning telco’s will no longer be able to maintain services to satisfactory levels.

The telcos will need to disconnect the copper network currently used to deliver these products on a region by region basis.

Introducing SIP

Put simply, some products you may have relied on are being phased out. But, don’t worry, as new products are already being rolled out and this is where SIP (Session Initiation Protocol) comes in.

Plenty on offer

With SIP, you’ll have IP access to your phone network and may be able to still use your existing equipment. (Please check with your provider if you are unsure)

Your business’ move to IP telephony can be geared to your requirements by using a combination of IP-PABXs, legacy PABXs and a fully hosted TIPT service.

Plus, you will no longer need separate lines for voice or data, since all traffic will be on a single IP network. That means you can streamline infrastructure to reduce maintenance and management costs, while making bandwidth usage more efficient.

In summary, SIP will:

  • Improve productivity – deploy powerful new communication and collaboration features.
  • Reduce call costs – manage costs with on-net calling for your business.
  • Streamline infrastructure – reduce the expense and inefficiency of separate networks.
