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 Vista M12 or Plantronics M22) is NOT required. All Plantronics Polaris headsets include the bottom cable to plug directly into your phone modular jack (see picture below):
