[asterisk-users] zapata.conf: cannot set txgain lower than -6.3 ?

2006-12-12 Thread Steve Hsieh

Greetings everyone,

I have a Digium TDM400P card with both an FXO and FXS module to connect to
the phone company and to a standard phone. The problem is that the volume of
my voice is going out too loud.

I tried lowering the txgain value in zapata.conf to compensate, but all
audio drops out completely if I set txgain to -6.4 or lower. If I set it to
-6.3, then everything works (but still too loud).

Is there a limitation as to how low txgain can be set? From voip-info.org, I
was under the impression that the range was -100 to 100. Even the page at
http://www.voip-info.org/wiki/index.php?page=Asterisk+config+zapata.conf shows
an example txgain of -15.9

Thanks.

Hi Steve,

I tried txgain as low as -18 without any problem, but I never tried
anything with decimal points.

Thanks for confirming that it can go that low. The decimal point doesn't
make a difference; I just added a decimal to determine the threshold at
which point things stop working (-7 doesn't work, but -6 does)
