Hello.
I'm running new phone wire in my house.
What's there now is solid four-wire cable with red, green, yellow and black wires.
It has a few splices in it, which is why I want to replace it with new wire.
What kind of wire should I run from the outside interface box to the inside jacks?
Should I use a solid wire like what's there now, or some cat5e or cat6?
Thanks in advance!
