mgetty might have something useful - see http://home.leo.org/~doering/mgetty/mgetty_15.html
thanks. Hmm, maybe it can be as simple as setting up fax support for just the black list.
From what I read on your link, it suggests the configuration
can be set to only accept for specified numbers. That way the listed phone numbers for telemarkers could get a fax response which can be really annoying. The next step may be to send any fax responses to /dev/null I just ordered a Wildcard X100P card for $5.95 through googlebase and started the build for /usr/ports/comms/mgetty+sendfax Maybe late next week I can try this approach and report back.
