[Asterisk-Dev] Echo cancellation

[Aaron Daniel]

I've got a slight problem with echo.  Basically, most of the outgoing 
phone calls on our system echo, but as far as I can tell, the incoming 
echo has been relatively fixed, with just a bit of work left to do on 
it.  I read somewhere that asterisk doesn't echo cancel on outgoing 
calls, am I wrong in that assumption, and if I am, what else can be done 
  when the echo training and echo cancel tapping isn't working?
