on 11/22/2005 remember to take an extension phone off of the hook. This will avoid "ringer shock" if a call should come through while working on the extension jack.

on 5/10/2007 I learned from the pro, a 4 conductor wire that is twisted is a must, pro wire will be marked UL listed NEVER use modular line cord to make extensions, the color of a basic 2 line circuit is

Red & Green, Line 1

Yellow & Black, Line 2
