Nobody has said that faxing couldn't use TCP/IP... and there's no reason 
why T.38 couldn't use TCP/IP.  Nobody has said that faxing couldn't use 
HTTP as a transport... or SSL... or any other kind of sensible 
mechanism.  Why in the world people try to keep faxing (data transfer) 
tied-down to audio channels by putting T.38 into H.323 or UDP/IP SIP 
beats me.
