Also, all this T.38 magic applies to V.21 (14.4 kbps) faxing.
As Scott Berkman can attest - we were mutually involved in a rollout
related to this some months ago - the Cisco T.38 implementation doesn't
support relay at Super G3 (V.34) speeds, nor does it detect Super G3
preambles properly in order to attempt a switch to T.38 at any relay
speed. Have fun with that. :-)
