If you can control what kinds of barcodes appear on the incoming faxes 
(and most people asking these kinds of questions are able to control 
this) then it has been my experience that a datamatrix (which isn't 
technically a bar code, but serves the same purpose and sometimes is 
mistakenly called a type of barcode) works best.  Furthermore, with 
libdmtx you have very powerful and free tools to do whatever work you 
need done.

So, for example simply putting this into FaxDispatch will load the 
$DATAMATRIX variable with whatever dmtxread decodes.

 DATAMATRIX=`/usr/local/bin/dmtxread $FILE`

Please see: http://www.libdmtx.org/

Thanks,

Lee.
