I was unable to find anything on this.  I would appreciate a pointer,
or some terms on which I could search and find this claim.

I have been fiddleing with NIST tones for calibration of audio apps
since 1997, but only recently has the subject of VOIP come up with my
customers.  As for why I posted in this NG, after following it for
some time I see that members here have a wide range of knowledge of
precision time and frequency topics.  I doubt that any VOIP NG would
have any interest or expertise in such things.
