[Freeswitch-users] freetdm rxgain txgain

[Karl Schmidt]

Looks like rxgain and txgain are not working - I was testing using the cool mW extension (thanks - 
whoever put that in)  and could not change the level - did some digging and dahdi_diag shows that 
the gains don't change.

Even tried changes over a reboot.


This card has absorbed a lot of time:
(Digium, Inc. Wildcard AEX410 4-port analog card (PCI-Express)) [OT]:(and now I find that it fails 
to put out a real ring signal.  Apparently, whoever designed it did not know the difference between 
RMS and peak voltage... fails to ring 3 out of 4 modems I tested. Gump, hiss,groan).

I can go in and modify the modem so it can detect the weak ring signal, but out of the box the audio 
levels on the card are way off ( they were also off in Asterisk ) and if I want to have this working 
well , I need to tweak those levels.


BTW - I can use the 1 dBm test tone stream to monitor the transmitted level - is there a way to 
monitor a level coming back the other way?
