Objet : modem protective device?


        While not strictly on topic, assuming they are still made this may
be of interest to those of you concerned with modems and wardialing.
        Some 20 years ago in a previous life I had a modem protective device
(a modem condom!) which fronted the modem on the phone line and when dialed
supplied a sythisized voice which asked you to "enter your code". You then
fed it a code via DTMF and it (if it liked your code) faked ring to the 
attached modem and then passed the call through when the modem answered.
This 
is of course very good protection against war dialing (which is the pen-test

relevance that I hope will get this through moderation :-)), since the war 
dialer gets a human (or semi human) voice not modem tones. The problem is
that 
several google searches on "wardialing modem protection" in various 
combinations turn up lots of articles on war dialing but no references that
I 
can see to the product that I want again. Does anyone know a source of such
a product? I find it hard to believe that such a useful device has died out!
