[comp.dcom.modems] Call Back Modem Systems

jim@eda.com (Jim Budler) (02/02/89)

I need to implement secure dialup for our factory. I envision a
callback controller, i.e. accepts incoming calls, receives the
touchtone codes, and passes this to the host computer. The host
computer accesses the callback database, and calls the matching
phone number on seperate Hayes-compatible modems.

Key requirements:

	1) Seperate dial in request line.
	2) One request line and callback database supports multiple
	outbound modems (4 to 16 modems).
	3) Sun 3, SunOS 3.5 compatible

Additional desirable feature:

	1) Dialback software implements additional password access
	requirements, so dialups have to satisfy access requirement
	before being passed to /bin/login.


Any information?

Thanks in advance
