Phone cords are a type of twisted-pair cable and use an rj-45 connector.

The answer is FALSE

The RJ11 is most commonly known as the "telephone" standard. Most wired landline phones almost certainly use an RJ11 jack or an RJ11 connector. RJ11 has between 4 or 6 wire connection, but only 2 wires are used for connection as compared to a RJ14 which is also used in connecting telephone lines and uses 4 wires for connection.
