Important Note: Plantronics Polaris Headsets can only be use with telephones with a headset jack built-in (ie. Nortel, NEC, etc). DO NOT BUY THIS HEADSET WITH A VISTA M12 or M22 AMPLIFIER. If your phone does not have a headset jack and internal amplifier, then the Plantronics H-Series Headsets with an external amplifier such as the Plantronics Vista M22 are a good solution.
