Wall of Wood (Score 1)

I just did the same thing for a couple of manufacturing buildings, including the business offices for both, and if you're going to be stuck in the same room I would suggest covering one wall completly with plywood and use it to mount your phone system, data / phone circuits, phone blocks, etc. Also, have all of your cabling attached to that wall using D brackets. Make sure you "map" it out on paper before you start mounting things. And for God's sake, make sure everything is ran clean and tidy. Don't forget to tag all of your cables.
