Just as an FYI - you have too many "Over"'s in your description.... 

FaxOverVoiceOverIP would make sense, but seeing as how "IP" is short 
for "Internet Protocol", saying "Internet Protocol Over Internet" doesn;t 
make much sense...

I would interpret that description as somebody trying to send a fax through a  
VoIP system using a voice-codec like G.711

However, there is the T.38 protocol which is designed to solve this exact 
problem, Asterisk support for it is just rather limited currently (pass-thru 
only).  

T.38 often gets referred to as FoIP (Fax over Ineternet Protocol)
