Was anyone able to come up with a solution for this?
I am experiencing the same problem as Louie. The phone connects correctly and I can make and receive calls however I am unable to hear the other person but they can hear me.
I have tried two different routers connected to my FTTP TPG connection, including the one supplied by TPG. I have tried Port forwarding & a DMZ, but still getting one way audio.
I have taken the phone to other sites (non-TPG NBN) and the problem does not occur.
Any suggestions appreciated.
