Tips: To see if this detangler will work with your phone system simply unplug the line cord out of your handset and count the contacts (pins) inside the handset's port. When you count the contacts you will find either 4 or 6 contacts. 4 contacts indicates it is an RJ11 port which this detangler is compatible with. If you count 6 pins then this detangler will not work as that is an RJ12 port. RJ11 is the most popular pinout in phone systems, so you will likely see this pinout when you count the contacts.
