I have successfully received a fax from faxzero.com on this
installation, as have I successfully sent a fax from freeswitch to the
PSTN fax machine in question.

I've been digging, but there doesn't seem to be a whole lot of
information on faxing.  I guess I could use a bit of direction.  Any
input is much appreciated.


Thanks!
