I think this is not necessarily a single problem. As I understood
Steve the 8 byte tiff file just means, that there was no fax received,
which can have various reasons.

I don't have a workaround so far, but I'll try to give as much detail
as possible of what's happening on my installation, in the hope that
it helps Steve to find out what's going wrong.
The Asterisk machine is a K6/333 (too slow?), connected to the
internal ISDN line of a small ISDN PBX (chan_capi). I've tried to
receive faxes from a real fax machine and from a fax modem with no
success. Both devices are connected to analog lines of the PBX.
I run Asterisk in verbose mode, and try sending a Fax from the
modem with sendfax (http://alpha.greenie.net/mgetty).
After some time sendfax prints out the following message and exits:
sendfax: FAILED to transmit 'f1.g3'.
Transmission error: +FHNG:20 (Unspecified Transmit Phase B error)
Asterisk's log looks like this:
