I would pull the wires out and put them into a 12 port surface patch panel

richms: 6 way plates are too tight to work with IMO, both installing them and actually getting your finger between plugs to pull them out.

I would pull the wires out and put them into a 12 port surface patch panel, loop thru a few sockets at one end to make your ones to jump for phone (say 9-11), use one of them for the unfiltered DSL (12) and the rooms on 1-5. Then use the pair splitters on the outlets you want to have analog phone available on.
