Welcome to the Community!
We were able to locate your account using your community details and the status of your home phone is active.
Where did you connect your handset? Is it directly to the UNI-V port 1 on the NBN NTD box? Please refer to this article: NBN Fibre To The Premise (NBN FTTP) Setup Guide
If it is, please send me a PM with your preferred time and best number to be contacted and I'll raise it with our Tech team for further troubleshooting.
