Well, I'd love to help---but I don't know anything about a 3Com NBX 100---although I'm sitting here with a two cabinet NBX with about 40 phones that I picked up over two years ago. I have all the books and a few CDs---. I'm in contact with a local IT guy who is taking care of one, and one of these days he's going to purchase some of this stuff from me, but in the meantime---it just sits here. If you really want to maintain one, make sure that's what you want to do before you invest a lot of time and effort into one.

Hope you get some action here one of these days....
