> Unscrew one of your phone jacks in the wall to see what kind of wire is behind it. If your house was built or renovated after the year 2000, chances are you have cat5, cat5e, or cat6 wires and there should be labels printed on the casing of the wires. (if you do see cat 5 or 6, you’re solid and it’s an easy conversion. If you don’t, it’ll be a lot tougher as new cat6 cables will need to be run in place of the phone lines)
