Desperately seeking fax spam filter.

We are getting more and more junk faxes, and
hope someone can help with a good fax Spam
filter like the type used for junk email.

We have a dedicated line for the fax machine.

Regards, Frank
 
That would have to be some sort of device that attaches between the phone
line and your Fax machine. It would have to receive the Fax, OCR it,
examine the OCR output for questionable content, then either dump everything
if its spam, or forward the native Fax file on to your Fax machine if OK; to
the best of my knowledge, there is no such thing. Your best bet is probably
here:

I need a "filter-in" filter, that is I give
my fax number out to clients, and then only
these have access, all others are excluded.
This works for junk email.

Somebody must make a "black box" to fit
between the line & the fax machine?

This "black box" could be programmed by a
computer. After all, the fax machine
displays the number of the incoming call.

The number which is displayed by the fax machine is the number which is
programmed-in in the setup of the sending machine. So it could be faked
-- although I regard the probability that a sending spammer matches one
of your clients' IDs as small.

But I see another option:
If all your clients send from phone lines which issue a CLI (calling
line identification), I recommend you look for a telephone device which
restricts incoming calls to those whose CLI matches one of the
registered ones. I think something like that is available in some small
scale PBXs.

If that's what you want, Google for "inbound call blocker" or just "call
blocker." These devices are primarily sold to block unwanted telephone
calls, but as far as the devices are concerned, there's no difference
between a voice telephone call and a fax call. You need to have Caller
ID (from the telco) in order for these things to work.
