Hello everyone I use ONT models EG8120L and EG8120L5 with VOICE service. I noticed that days after the installation on the client, the phone has a lot of hiss, resolving only by restarting the ONT.
however this problem occurs randomly, some clients more often and some not. I've done tests with other phones, wires, etc. and the problem resolves if I restart ONT or reconfigure it.
I checked firmware too and it's current.
I would like to know if there is any configuration or adjustment that I can make, or if it is any adjustment due to the fact that I live in Brazil.
Thank you very much in advance
