If you're using a TDM2400 you can buy a hardware echocan module or HPEC (which
is a proprietary software echocan) if you desire (or need), however...

...either of those options won't resolve the "Unable to enable the echo
canceller".  After you set 'echocanceller=mg2,1-24' in your
/etc/dahdi/system.conf file, did you run dahdi_cfg?  Also, what is the output
of 'cat /proc/dahdi/1'?
