[Asterisk-Users] Gain settings

[Jim Archer]

Hi All...

I am using Asterisk on Debian with a single FXO card.  I find that when I 
dial into it it sounds very soft.  I also noticed that when I record VM 
greetings (I use the USB device for FXS) they are very soft.

I saw the rxgain and txgain.  Can some one tell me how these are used?  I 
have seen examples with 0.0 and others with 100%.  I have played with 
integers and found they can make it very loud and distorted.

Whats the proper system?

Thanks...

Jim
