I have had voip for at least 6 years. It has been unreliable, often dropping out and requiring a modem reboot, and of fairly poor quality. Now it doesn't work at all, despite several modem reboots. The usual lights are all on and I get a dial tone but when I ring a number the handset gives a ringing tone for two rings and then gives an engaged signal. When I ring my own mobile the voip handset gives the sound of two rings (before cutting out) but the mobile does not register any rings.

We had an outage affecting the Homephone, VoIP and NBN services nationwide last night and has been cleared. We would like to confirm if you're still having difficulty with your VoIP/Home phone service.
