Plantronics Polaris models are only compatible with phone systems that are "headset ready" (usually marked with a headset symbol or labeled "headset" on the bottom or side of the phone). Such telephones have a built-in amplifier. A Plantronics amplifier (such as the Plantronics M22) is NOT required. All Plantronics Polaris headsets include the bottom cable to plug directly into your phone modular jack (see picture below):
