asterisk users - Mar 2005 - Echo for first 15 to 20 seconds

I am using asterisk with a handful of DM04B cards. Everything seems fine except
for an echo on all calls on the local end of the call. In almost all cases the
echo goes away after 15 to 20 seconds. I am attributing the echo going away to
the echo cancellation code that was enabled when the following options are set:

echocancel=yes ;
echocancelwhenbridged=yes
echotraining=yes ; 

Is there anyway short of playing with these options which I have already done to
improve this echo issue.

Instead of echotraining=yes, use echotraining=800 and don't forget
to 'stop' and restart asterisk. A simple reload won't cut it.

I thought echotraining=400 was the default?


Cheers,
Dean
