[QUOTE="SPECIAL LOCATION, post: 11568, member: 250"] Yep good idea.. I also have a test phone... but as I said on one of my earlier posts.. many modern phones (with electronic ringy sounds) don't actually use the 3rd bell wire.. they just pick the ringing direct off the two A&B wires. so you can still get ringing sound with 3rd wire open cct! Whereas generally the physical BELL,, metal dome that rings! generally does use 3rd wire.. so you prove all of your wiring to a more thorough level! ;) :D :) [/QUOTE]
