[comp.dcom.modems] Recommendations on call back modem system

Does anyone know of a good call back modem setup that allows the user
to call in to a phone number, get a computer voice that asks for a
code sequence, and if the user types a good one, calls the user from
an internal database?  (Something like 'defender'?) Or one that allows
the user to call in with his/her computer and ask for a password with
the same result if correct?  I have used defender before as a user but
don't know how to get in touch with the company and have used the other
type before also, but can't seem to find an article about them.  Any one
can give me a recommendation and where to reach the company that makes
it would be appreciated.

Thanks in advance,

Ben
