I did try fxotune.. it did wonders on echo and audio quality when
dialing in.
Before the zapata upgrade it did nothing (the -d -b options weren't
there).
I found a page on voip-info.org that talked about using the new version
and
followed what was there:
amportal stop
./fxotune -d -b 2
./fxotune -d -b 3
./fxotune -d -b 2 -w 1004
./fxotune -d -b 3 -w 1004
./fxotune -i 5 -t 1
./fxotune -d -b 2 -w 1004
./fxotune -d -b 3 -w 1004
./fxotune -i 4
./fxotune -s
amportal start
/etc/fxotune.conf:
2=5,3,251,250,2,253,255,255,254
3=5,1,248,252,4,253,1,0,0
If I run just plain old fxotune -i 4 then I get this in fxotune.conf:
2=14,0,0,0,0,0,0,0,0
3=5,0,0,0,0,0,0,0,0

Also although the 400P card says it's a revision J card it is detected
as a revision I card:

Hi Carlos,
- send us your interrupts configuration: cat
/proc/interrupts
- try adjusting
line impedancy; see fxotune on zaptel source directory.
cheers,

Asunto: Re: [Asterisk-Users] Low volume/ audio problems on
TDM400 card
That is the first thing I did.. rxgain seems to help to
make it louder when the two PSTN lines are bridged but also affects
the audio quality adversely. It's very touchy.. it also causes
horrible feedback (loud screeching when lines bridge).
I've upgraded zapata and libpri too.

I've been attempting to
get this TDM400 card to work since March.
While it sort of works, I'm having a lot of audio issues with it.
I am on Asterisk 1.2.9.1 svn rev 32797 and Zaptel 1.2.6.
I've tried moving it to beefier hardware, upgrading asterisk/zaptel/etc,
moving the X100 cards around on the TDM400 card, nothing seems to fix it.
The card says it's a revision J card.
I get low volume on the receiving end (too quiet to hear when channels bridge) and
adjusting rx/txgain to comfortable levels causes popping and clicking when
calls are made that cause bridged channels. Upgrading to the newest zaptel fixed the horrible echo
and feedback issues I was having.
Before I send it in for a replacement I thought I'd ask about it in case there is a setting
I can make to fix it.
