[asterisk-users] Dahdi Echo canceller setup

[Ira]

Hi

I have a TDM400 and 4 channels of HPEC. I don't use the POTs lines 
much so I didn't realize it wasn't working. This morning I was 
watching the console and noticed that the echo canceller didn't load 
when a call came in. /etc/dahdi/system.conf showed mg2 for all 4 
channels. I changed them all to hpec and then restarted dahdi and 
Asterisk and suddenly HPEC was working.

Is there something I need to do with HPEC to make sure the 
dahdi_genconf generates a proper system.conf or is there somewhere 
else I show tell asterisk to use HPEC?
