Was it like watching a 106' plasma at 1080p for the first time? <grin>

I found it quite interesting the first time I used a Polycom IP650 (the first wideband capable hardphone to arrive at Digium) that the voice quality was much improved even using G.711! Presumably this is due to using higher quality speakers, mics and other audio bits required to provide wideband audio quality, but it would appear from this (exhaustive) sample set that in fact many phones (even from high end manufacturers) don't even provide the maximum audio quality achievable with G.711. -- Kevin P.
