only when my client call or receive a call , no sound(audio) , no tonality , nothing.
before, "snomone" was installed on Windows xp , i upgraded this to Windows 10 , but the problem was the same.
this problem it's very important for my customer, yesterday i updated "Snom One" to "Vodia PBX" , and since , i don't have any more problems , i'm verry happy for this , but i activated a trial version (for 30 days to test it) of Vodia PBX ten (because my licence - snom one premium ten is not compatible with "vodia pbx" software)
