I should have probably included some instructions on using the backend.
To build the spandsp backend, you will need spandsp installed.  It can
be downloaded from http://soft-switch.org.  Once spandsp is installed,
Asterisk can be configured and built in the normal manner.

All faxing operations are done through the SendFAX and ReceiveFAX
dialplan applications.  They accept a TIFF file as either the file to
send or as the destination of the received file.  More information can
be found in the documentation for those two applications.

Thanks.
