I can't get any echo cancelation at work, also not the hardware ones 
from digium like vpmoct128? I asked about it on the IRC channel, but 
there i was told there is no support for echo cancellation at all, but i 
see lot about this in the code (zapchan.cpp). Anyone can help me with this?

What you've seen in the code are the requests made by Yate to the driver 
to start/stop echo canceller or echo training.
BUT: THE CARD MUST HAVE A HARDWARE ECHO CANCELLER
