It's a sampling problem. VOIP does not sample voice at the same rate as
the POTS line does. Running an all-analogue device over a digital
carrier can "look" like watching a pc monitor that was taped by a video
camera. It just doesn't sync up right. Running analogue fax over VOIP
like Vonage (and CBeyond where I first ran into this problem) requires a
sample rate compatible with fax data rates. Some integer multiple of fax
speed is required or else there is frame drops and/or broken frame data
fields. On the far end of this there is now a very confused fax machine.

Voice data over the fax line will sound different using VOIP. POTS
doesn't care since it's all the same stuff to it.
