Question about echo cancellation in DE410P

After run /usr/sbin/dahdi_genconf, /etc/dahdi/system.conf shows "echocanceller=oslec,1-15,17-31".

Since the card is bundle with hardware echo cancellation, Should I disable the oslec software echo cancellation by adding "#" in front of above script?

Thank you

hello:
you can set the echocancel=no to disable the software cancellation.
please put ; in front of the script.
regards!

Do you mean that I should add something in /etc/dahdi/system.conf like follows:

echocancel=no
echocanceller=oslec,1-15,17-31

Right?

Besides, how about the follows in /etc/asterisk/chan_dahdi.conf

echocancel=yes
echocancelwhenbridged=yes
echotraining=800

Should I set the above to "NO" and add pound key in front of echotraining=800?

Thank you

hello:
yes. echocancel=yes, and
=========================
;echocancelwhenbridged=yes
;echotraining=800

After added "echocancel=no" in /etc/dahdi/system.conf, the following error message display:

Running dahdi_cfg: Notice: Configuration file is /etc/dahdi/system.conf
line 11: Unknown keyword 'echocancel'
line 19: Unknown keyword 'echocancel'
line 27: Unknown keyword 'echocancel'
line 35: Unknown keyword 'echocancel'

Any idea?
