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

<blockquote>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<br>
the audio quality adversely. It's very touchy.. it also causes
horrible feedback (loud screeching when lines bridge). <br>
I've upgraded zapata and libpri too.<br>

<div text="#000000" bgcolor="#ffffff">I've been attempting to
get this TDM400 card to work since March.<br>
While it sort of works, I'm having a lot of audio issues with it.<br>
<pre>I am on Asterisk <a
onclick="return top.js.OpenExtLink(window,event,this)"
href="http://1.2.9.1" target="_blank">1.2.9.1</a> 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.
