NOTICE the picture of this cord laying on an iDCS 18D phone.Relaxed the curly part of this cord is about 40 inches long, NOT 25 FEET. This manufacturer calls it a 25 foot cord because 25 feet of material is goes into the curling machine. This naming scheme is confusing, but it's the industry standard.
25 foot cords should not be used on desk phones unless precautions are taken. The cord needs to hang by its own weight to keep the coils from tangling. This holds true for any manufacturer. De-tanglers won't help.
