You're going to need the password and a laptop with hyperterm or equiv.
In my hotel, I was able to make an extension for my desktop with HyperTerminal, and I have a modem for extension 299. I just dial up 299 through hyper terminal and log in that way and I can access the settings. I changed the Extensions to show the proper Room Number/ Locations.
