[AG-TECH] Echo Cancellation

[George Estes]

Markus,

    Just wondering what your analysis involved and what results you saw?  I 
have used both, but never really tried to compare the two.
ps.  The last time I used the EF2280 I didn't think the software interface 
was very well developed, compared to Gware for the XAP800.
