1043,
I don't have experience with the Avaya one-X, but I did get list pricing and features. (I totally missed the part about no IP solutions - sorry!) But since I need to finish what I started - You can get an office setup with loads of features for hundreds per seat (not thousands). Thought it may be worth looking into for feature rich, ease of setup and low cost. Going IP can sometimes save you cost on wiring as well. As far as analog devices, I'd just order a seperate line for FAX/Modem in small office you can usually share or use e-fax features with an all-in-one fax/print/scan/copy device.
