IMPORTANT NOTE: If you have a self-contained "consumer" 2-line phone, we do not recommend the use of an extension cord or a 25-foot line cord, because of the strong possiblility of getting crosstalk (bleeding of a conversation or noise from one line to another). If you need a long cord, use the special anti-crosstalk cord shown on this page, which has twisted pair construction, rather than four parallel wires used in the extension cords.
Some multi-line "system" phones that have separate wire pairs for "voice" and "data" also need twisted-pair cords.
This convenient cord allows you to easily plug in two phones, or a phone plus an accessory, or two accessories, up to 25 feet from the phone jack. Neutral almond color. Costs less than buying a separate 25-foot line cord and splitter. Not dollar store junk.
NOTE: With some phone systems, you may not be able to connect two devices at one time to one jack.
