About Plantronics Audio Processors
Most phones do not directly support the use of a headset; they need an audio processor, amplifier, or other adapter in order for call audio to transmit properly to and from the headset. Plantronics audio processors/amplifiers enable the use of our H Series headsets with most desk phone models. Note that when you purchase an audio processor, it comes with the cables you need to connect to both your headset and desk phone.
To learn if your phone requires an audio processor, refer to our product configurator. If your phone does not require one, choose one of our direct connect cable options.
