yeah, what you have to do is download the user manual and read your butt off. I'm in a small business trying to set up the exact same thing except with about eight phones. The programs are garbage, you have to do everything manually. I would suggest first setting up each piece with a static... the 9000 and 400. Mine is like 192.168.1.60 (spa9000 ip) and .70 (the 400). From there you log into each peice and configure it using the manual. Its written well, but takes some getting used to. Good luck.
