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.
