[Freeswitch-users] softphones and background noise

[Juan Pablo L.]

Good morning, i m having lots of issues with softphones, when a call is initiated/terminated to a softphone 
the background noise is too high that you can hardly hear the actual voice.
i have played around with VAD and CNG turning them on and off in the profile and/or the dialplan but i have not had any luck.
it does not matter if the call is internal or goes through a gateway, it is however, worse when it goes through a gateway, those are the
cases you can not even hear the voice for so much noise and when the call is to a next extension the background noise is high
but not as high.
But, if you initiate/terminate the call to a hardphone (like polycom phones) the call is perfectly clear in all cases 
(except when the other end is an internal softphone).
can someone please give me a hint. thanks a lot!
