I've been going nuts lately trying to get rid of an annoying echo
problem that makes my asterisk server unusable when clients try to call
me.<br>
Here's the breakdown of the issue - Hoping that someone can throw me a
clue:<br>
My setup is as such:<br>
Single AMD Athon machine with X100P clone card and voip through
multiple providers .<br>
<ul>
<li>Inbound calls through the X100P that do not bridge to voip are
fine.</li>
<li>Outbound calls that do not bridge with the X100P are fine.</li>
<li>PSTN ->*->VOIP calls have so much echo on the called party
side (sidetone) that it is almost impossible to have a conversation.</li>
</ul>
I've played with rxgain txgain, echocancelwhenbridged,etc nothing seems
to work. Yes Im completely restarting asterisk and running ztcfg.<br>
<br>
Anyone figured this out?<br>
Heres my zapata.conf :<br>
