What error message from where?
With Zaptel the echo canceller "settings" are global (that is: one
hard-coded echo canceller). With DAHDI there are echo canceller modules
and you can (and actually need to) set them per-channel.

<pre wrap="">It might have something to do with the
RCBFX drivers, I'm not sure. I found your page and followed your

dahdi_cfg -vv. That's where I got the message. Don't have my notes
here so I don't have the actual error message right now.

I don't remember the actual error name, but it showed up when I did
dahdi_cfg -vv. It was something like "DAHDI_ATTACH_ECHO_CANCELLER
Failed for Channel 1. Unsupported command (22)".<br>
<br>
I was trying to see if maybe it was logged to my syslog but this is
all I find in my /var/log/messages:<br>
