This is nothing new; the echo canceller on a channel is not enabled
unless the channel is in an active call and the call hasn't caused it to
be disabled (via tones). If you are looking at a channel that is
inactive, this is exactly what you will see.

That is not valid syntax for /etc/dahdi/system.conf, correct syntax
would be 'alaw=1-4'.

Note the phrase "(in microseconds)" here. This behavior has changed from
Asterisk 1.4, and is documented in the documentation that came with
Asterisk 1.6. If you haven't read the CHANGES and UPGRADE files
thoroughly, you are spending time trying to understand things (assuming
they are problems) that you don't need to spend.

It sounds like you are trying to do a major upgrade without actually
taking the time to learn what has changed and what that will require you
to do. That's really very important, which is why we spend time writing
that documentation in the first place :-)
