Disabling echo cancellation by software

Dear, I have Asterisk 1.6 with an E1 Digium card with echo
cancellation module. So I need to use just the echo cancellation by
hardware and disable the echo cancellation by software. I use DAHDI
for my telephony hardware.

If the lines involved with echo cancel are:

In /etc/asterisk/chan_dahdi.conf:


What lines do I have to comment or to change the value if I want to
disable echo cancellation by software ???

Thanks a lot,
