Hi, Complete Asterisk noob here,
I just have a few general questions I need to ask before I start
installing it:
If I want to setup Asterisk simply to respond to echo calls (SIP calls
from a softphone only), do I need to install AsteriskNow as well, or can
I simply configure dialplan to do that?

'echo calls' doesn't mean anything to me. What does it mean to you?
I think you refer to the echo test that comes with the default
extensions.conf file. Within the regular installation of asterisk on the
extensions.conf file you will have an echo test extension. I don't think you
need asterisk now for that.

calls. The echo is always from our voice echoing back to us. How can
I fix this echo? I have tried installing the VPMADT032 module on our
I think you need to remove the line echocanceller in system.conf
You could also try to use fxotune, it'a really improving things.
You also need to put echocancel=yes in chan_dahdi.conf

Hi -
I am having echo issues on our Asterisk box using a PRI circuit. I was
using the software echo cancellation and that helped a bit but didn't solve
it completely. So I went and bought a Digium echo cancellation module for
the TE121 card. That made it even worst, getting more echo on

What were you running before you upgraded?
So, Asterisk doesn't start echo canceling a
