To quote the Mythbusters, "there's your problem".

Fax over IP = forget it unless the connection between your two Asterisk
machines is some form of LAN connection.  This *may* change a little
when the T.38 support in Asterisk includes a gateway mode, which I don't
believe it does yet. (IIRC 1.6 includes much better support for T.38,
but I don't think it includes this kind of gateway yet - anyone care to
correct me?)
