I've long suspected and we've discussed it on VUC many times, that
Polycom uses what used to be know as pre-emphasis and de-emphasis like
techniques to make them sound so good. They really are great, even on
th elow end, and with g722 enabled, they get even better. We are
currently testing a sub branch of the weekly Friday conference using
the ZipDX HD conference bridge and it does make a difference.

Maybe you'll drop in sometime soon Kevin? Otherwise, probably see you
in Rostock in May.

Best,

randy
