Most Australian businesses use ISDN for their phone service, but did you know ISDN is being switched off? ISDN services will disconnect as part of the nbn co’s rollout.

But it’s not all doom and gloom, there are services available that provide a cheaper, more flexible & scalable solution for your business.

Here’s what you need to know to stay connected:

What is ISDN?

ISDN (Integrated Services Digital Network) allows voice and data to be delivered simultaneously over the public phone network. This lets your business handle different types of services like voice, data and video.

When will my ISDN service cease?

Telstra has announced the end of sales for ISDN commencing January 31, 2018 with an end of life for ISDN services by 2022. In addition, your ISDN will likely be disconnected when the NBN service is rolled out in your area.

What’s replacing ISDN?

SIP Trunking or Session Initiated Protocol offers a number of advantages to businesses looking to move on from ISDN. It uses Voice over IP (VoIP) to bring together voice and data services, which automatically saves you money by eliminating the cost of line rental and reducing voice call costs.
