Dear All,
we have a problem in voice quality ,
we use cisco as5350xm and use our special software as a PBX.
also there is a very heavy traffic of calls which are handled by operators. but the only problem is the noise in the calls. there isn't any echo and
also we have adjusted input gain and output attenuation with different values such as (+3,-3) (+6,-6)(+6,-14) and so on.
but the problem is remained. how we can remove the noise , which voice quality parameter decrease the noise ?
we also configure disable comfort-noise and all voip dial-peer are set to No VAD.
any suggestion will be appreciate.
