I'm sure you didn't quite mean to write what you have said above. Fax
transmission builds upon exactly the same ITU-T standards as data
transmission. For example, 33.6 kbps fax transmission (so called "Super
G3") uses the same V.34 standard as 33.6 data modems. At slower speeds,
fax modems use a half-duplex standard that is less complex than that
used by full duplex modems running at the same speed.
If there is a problem with Digium hardware handling fax signals it
cannot be laid at the purported "massively more complex" signalling of
fax transmissions.
