Welcome to the Community!
We were able to locate your account using your community details and tested the line, but was not able to detect any fault within the NBN network.
The phone status shows that it is active and working properly.
Based on the message that the caller received, they need to double check the number as they are calling a phone number and not a mobile number.
Advise them to make sure to enter the correct area code along with your number.
If the issue persist, please contact our Tech team directly on 13 14 23 Option 2 for real time support.
