We've had VG-200's providing transcoding services for our G.729 users when accessing Unity for a couple of years. Recently, we've added CMM's to our transcoding resources. When using the CMM to transcode between the user and Unity there are occasions where there is high volume white-noise injected into the voice stream. It was so bad I had to yank the CMM's out of production and go back to the old war-horse VG-200's. Anybody else seeing this occurance?
