No Dial Tone: NBN Troubleshooting

If you're unable to use your phone and you're connected on the NBN please try these troubleshooting steps. If we're unable to help you restore your phones' connection in this guide, then the steps will provide info on how to report the problem to us.

Step 1 - Is your NBN broadband service still working?

Step 2 - Restart your NBN Modem

Remove the power cable from the back of your modem for 10 seconds, then plug it back in. After approximately 2 minutes the lights on the modem should settle into a stable pattern

Step 3 - Check your phone

At times the wiring may be what is causing your issues. Plug your phone directly into your modem's telephone ports to eliminate your internal wiring

Is your phone working now?

  • Yes - Great! I'm glad we could fix your issues
  • No - Continue to the next step

Step 4 - Give us a call
