I responded to your initial post about the mobile reception issue located here. I will include this home phone issues with the investigation and provides the feedback on your 1st post to avoid redundancy. Please shoot me another PM with your home broadband internet account details.
NBN line was broken for a while. Today the cable was replaced, but the phone does not work. Router logs show repeatedly:
- Register to server address 172.xxxxxx:5060
- account[03xxxxxxxxx(0)] registration error, status=401
