Hardware echo canceller

Folks!
Hi Im using Asterisk 1.6 and currently have echo problems. Im using AEX2400 and whenever I make a call when I type “dahdi show channel xx”, (xx is the number of the channel that I`m using in that moment to make a call) I see "ECHO CANCELLER is OFF"
How can I figure out if the module is ok?

Here is what I have configured in chan_dahdi.conf:

echocancel=yes
echocancelwhenbridged=yes
echotraining=yes

Do I need to configure something extra to make hardware echo canceller work?

Thanks a lot!!!
