[Asterisk-Users] S100-FX v2 audio quality

[sdcharly at gmail.com]

Hi all,

I have 2 of these with me and from day 1 im facing issues with the
background noice i have done all sorts of testing but all in vain. the
changinf of poer supply reduced noise to certain extend but still its
very clearly audible.

A good fix would be really helpful to me

Thanks
