Since NBN was installed I have not been able to use my landline - it is plugged into the Phone 1 port on the router. When I try to make a call all I get is a continuous tone rather than a dial tone. Not sure if removing the ADSL phone connections would help.
If you have another handset connected to a different telephone socket, kindly disconnect it. Your VoIP service shows registered here and it should be working. We are suspecting a possible issue with the set up, but if the issue persists after double checking it, please let us know so we can investigate further. Thank you.
