Fxotune echo ratio

Hey all,

I’m running Zaptel 1.4.0 and Asterisk 1.4.1 and having some difficulty getting fxotune to work.

when I run “fxotune -d -b 2” it reports:
[color=blue]Dumping module /dev/zap/2
echo ratio = 0.6589 (3004.0 / 4559.4)
Done![/color]

but when I run “fxotune -i 5” and “fxotune -s”, “fxotune -d -b 2” reports the same results. Looking at the fxotune.conf it shows that only the firs channel was modified:
1=5,0,0,0,0,0,0,0,0
2=0,0,0,0,0,0,0,0,0
3=0,0,0,0,0,0,0,0,0

I tried modifying these values by hand but it didn’t appear to have any effect. Does anyone know what these value mean?

How can I get fxotune to tune my second and third channels?

Thanks,

Mark MacVicar
