We have a T100P and a TE405P on Supermicro dual Xeon 2.8, SCSI backplane, 
*server* systems...  we get some echo on some calls out to the Bell Canada 
PRI, and some on calls through nufone.  It's definitely destination related 
for us.

The T100P connects to an Adit600 FXS channel bank which goes to our Meridian 
MICS -- Eventually I'll be replacing the channel bank and POTS trunk lines on 
the MICS with a proper PRI card.
