It uses a single pair but on the outside pins (white/orange pair on T568B)
There is an 8 port DKSC and a 16 port DKSC16.
I guess it depends how many phones you need to have wired up. I do not like using patch panel for voice, but if I had to do it this way,I would run 25 pair cables with amphenols from the KSU to the patch panel. Punch down each pair to a port and you are good.
