After my NBN connection has been completed my home phone number cannot connect to 13 Numbers.
Dialing other numbers is ok and receiving calls are ok, just not able to dial 13+ numbers.
After initial dial tone I just get a shrill constant tone when the 13 number is dialed.
Welcome to the community,
Could you please send me a PM (private message) with your Full Name, CID (customer identication number) and your mobile phone number, so I can take a look at your service?
