asterisk users - Sep 2009 - DAHDI TDM440E still has echo on bridged connections

"
Hello,

Strangely i purchase a TDM440E with the echo canceller onboard and I still
receive a horrible echo and i'm only
using bridged connections between DAHDI/4 and DAHDI/1.  I turned of echo
cancellation on bridged connections which seemed to help alittle bit.  I ran
fxotune -i5 and setup fxotune -s to apply settings on startup, which has helpped
but there is still echo on the begining of each call. Any idea's as to why
there would be an echo at the beginning of a bridged conversation with echo
cancellation turned off?

Also this only happens on incomming calls not outgoing calls


Thank you,
Brad Finberg
