I know that ADT (the company that makes the echo cancellation 
algorithm) has received some of the sample audio files and are working 
on trying to fix it.  We are working hard to solve this problem.  All 
things considered, I have heard (with the new echo canceller) that if 
you set echocancelwhenbridged=no it makes the problem go away.  Have 
you tried that?
