Plantronics offers Electronic Hook Switch (EHS) cables for many phone models (Avaya, Cisco, Polycom & more). This allows you to answer / end calls at the touch of your headset button. If an EHS cable isn't available for your phone model, the Planbtronics HL10 handset ilfter will allow you this same functionality.
Corded Desk Phone
Recommend an optional EHS Cable or Handset Lifter (HL10) for best experience. This allows calls to be answered / ended with the headset button.
