Change is afoot

Your telco such as Telstra may have got in touch with your business about how the way our Internet and telephony connection is going to change in the next little while. With the NBN business grade rollout, that change involves ISDN vs SIP – and here’s what you need to know before it’s too late.


At the moment, unless your business has made the switch to the NBN – the rollout would have occurred in your area and you would have been alerted – you may still have ISDN and may know little about SIP. The latter is the way of the future and you may be pleased to discover it can greatly benefit 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 Telstra will no longer be able to provision and maintain services to satisfactory levels.
  • The telcos will be required to disconnect the copper network currently used to deliver these products on a region by region basis.

Introducing SIP

As you can see, some products you may have relied on are being phased out. However, new products are already being rolled out and this is where SIP (Session Initiation Protocol) comes in.

It’s simpler

With SIP, you’ll have IP access to your phone network and still use your existing equipment. Your phone system will be simpler and you can use IP voice functions.

Your business’ move to IP telephony can be suited to your needs 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.
