Since the file you're referring to is in DAHDI, any debug messages will go
to the kernel log.  You will not be able to see those messages in the
Asterisk CLI.  One way to check that the echocan is working is by checking
the appropriate entry in /proc/dahdi.  Another way to check is "dahdi show
channel #" in the Asterisk CLI.  IIRC, it tells you if the echocan is active
or not, but not which one is active.
