A telephone handset universal connector is used to connect between a phone base having a set of four signal outlets, and a handset having a set of four corresponding signal ports. The telephone handset universal connector includes a universal circuitry and a selection switch. The universal circuitry has an electric output 101 for electrically connecting with the four signal outlets of the phone base and an electric output 102 for electrically connecting with the four signal ports of the handset, wherein the selection circuitry provides twelve connection combinations for selectively connecting between the four signal outlets and the four signal ports. The selection switch is electrically connected with the selection circuitry to selectively switch the selection circuitry within the twelve connection combinations.
