I have recently bought a VS-GW2120 with 4 modules VS-GWM400W, and the quality of the calls are really poor, each module has configurated with this DAC=-15 ADC=-3 , i have other gateway Dinstar and i do not have this problem.
Sorry for the trouble. Can you give me remote access for a check? Teamviewer11 is ok.
When you are ready,please feel free to contact me. It is very convenient if we can contact via skype. My skype id: This email address is being protected from spambots. You need JavaScript enabled to view it.
