Gain control on Qudro 6FXO

meerkat71 · 04-07-2009, 05:54 PM

Greetings,

I have already set the Transmit gain control to +6 on the Epygi, but from a training session at the distributor I know there are some hidden pages where I could "tune" it some more, since the client still complains that when they make pstn calls the other party cant hear them. Incomming calls (from pstn) is fine. Could anyone tell me where to access these pages?

Thanks in advance.

I am not aware of such additional pages. And I would not recommend to try to increase the gain even more, as this will cause echo problems. The +6 is the maximum you can do without big risk of introducing echo. I think it will not help, if customer will be happy with volume, but start complaining to echo.

But also I don't think there is any problem with gain there. If they can listen the voice OK (in both directions) on incoming calls, it has to be the same on outgoing calls too, as there is absolutely no difference between incoming and outgoing call, as soon as the call is established (given that the calls are done through the same FXO ports).

May it be that the incoming calls go throgh different FXO ports, than incoming ones?

Best regards,
David

P.S. Did you try to increase the volume on IP phones they are using?
