When you connect hyperterminal to the serial port, communications to the DSU should be instaneous. You will either see a little heart beat on your laptop monitor or the date and time from the DSU. If you hit the enter button, the DSU should ask for the password prompt. Email me, and I will provide you with what is the standard password. The standard password may or may not have been changed by the original installer.

Once you have the password, the DSU will provide you with menus to select from.

Re: the $800 voice mail. It will NOT probably be enough, unless you can find a used one. A 2-port Debut from Comdial runs about $985.00 and a 4-port is about $1,500.00. I will caution you that if you use the Debut system from Comdial you should also place it on a small UPS because the Debut is very toucy about having clean power. If it burps or hiccups because of dirty power they have been known to crash and a lot of times they will not recover unless it goes back to the factory for repair.
