In generaly this is a bad idea (especially dialup internet). If both the 
gateways you use support T.38 origination/termination then faxing will not be 
a problem at all.

However, in your case I assume you are only transporting the calls over LAN, 
and there is no WAN/Internet involved... which means you will probably achive 
a high success rate for both dialup and fax... I wouldn;t be surprised if you 
can;t max out the baud on your dialup internet connections though... i'd 
expect a slight reduction in speed (and errors, though error correction built 
into your modem would hopefully take care of this, at the cost of a a little 
speed due to re-transmissions)
