I work in a large warehouse and need to move a phone across the room, about 120 ft. I made a cable using CAT 5 and used a 6 conductor phone connector, but cannot get phone to power up. The phone is an inter-tel multi line phone system
. I tested the line I made with a data cable tester, all 6 wires give signal, and the phone only needs two working wires to work. When I plug in the wall jack, the tester shows Volts! so I don't think there is anything wrong with the line. However, When I plug in a shorter phone line about 25' the phone works. I tried using a data coupler for phones and extend the line that way and it stops working.
So is the problem the distance of the cable? There is probably about 300ft of line leading up to the wall jack. So the line I made would make it 400+ ft. But to my knowledge phones can handle great distances. So I am not sure what the deal is. Would changing the connector to a 4 conductor make a difference?
