What makes you think its the modem? It is more likely to be the 
international circuit. A lot of these will no longer carry FAX, as they 
use low bit compression for the voice. Some handle FAX specially, using 
something like T.38. A lot do not. A line has to be pretty bad for the 
V.21 stuff to fail, so a low bit rate channel is quite a likely 
possibility.
