If you want to send a fax, you first need a suitable
tiff-file. You can create such a file from a *.ps
using

 gs -q -sDEVICE=tiffg3 -dNOPAUSE \
                   -sOutputFile=letter.%03d letter.ps </dev/null 

This will produce a tiff-file for each sheet of the ps-file.
You can merge those several files to one tiff using

    tiffcp file1 file2 ... fileN out.tiff



To send a fax, you can add the following entry in your
extensions.conf:

    exten => 1234,1,txfax(/home/steveu/testfax.tif)

Then go to your fax machine, dial 1234 and you will receive
your fax (depending on your fax machine it might be neccessary
to hit the "start/dial" button again, if the asterisk answers). 
It should also be possible to send the fax straight
from asterisk, but currently I don't know how.
