I bought a Digium TE411P hoping the hardware echo canceler would improve 
my echo problems over the software echo canceler, but had no performance 
improvement. Since then I have heard that the Digium T1 cards use the 
same algorithm for both hardware and software echo canceling so hardware 
will only work better if your CPU is overloaded when doing software echo 
canceling.
