[asterisk-users] System noise reduction

[Sunny Du]

Hi team,

I noted there has a little system noise while I dial into system. I do
believe it is generated in system as I would heard those noise even I was in
CDR. would anbody guide me where is the noise system generated?

It is second time I meet this issue, last time was fixed by change from alaw
to ulaw. But no luck is time...


Regards,
Sunny
