Mediaproxy doesn't care about the content of the media streams. AFAIR, 
the real problem with T.38 and NAT between two endpoints A and B is that 
B waits for T.38 packets from A before replying, but mediaproxy needs at 
least one packet from each A and B to be able to bridge together the 
streams (otherwise it doesn't know to which NAT ports the streams have 
to be redirected).

Just my 2 cents,
Andy
