I just read DueE's "Laptop connection to NAM" and I think I am even more confused, but then again, that's not hard to do. I have a Nortel MICS with Norstar Voice Mail 4.0. I need to change the Class of Service, Password Expiry setting to '0'. I did this with 2.0 by attaching to the NAM II serial port with HyperTerminal and accessing the Application Administration menu. This does not seem to work with 4.0. When I attach to the NAM serial port, I get no response on HyperTerminal. We do not have the Norstar Voice Mail Manager option but we do have a network card. I have tried connecting through the network card with no luck. I even have a copy of the Voice Mail Manager software that I tried using, but still doesn't work. Any suggestions?
