Plantronics EHS Cables

Plantronics Electronic Hookswitch (EHS) adapter cables work in conjunction with a wireless headset system to provide remote alert and call answer/end capability when used with a variety if advanced desk phones.  This means that when when you are away from your desk, when the phone rings, an audible signal is sent to the wireless headset, and the user can answer the call remotely by selecting the Call Control button on the headset. Similarly, the user can remotely end the call. EHS cables remove the need for the older electromechanical HL10 Handset Lifter. Phone systems that support the EHS capability include models from Avaya, Cisco, Polycom and ShoreTel to name a few.

EHS capability is supported by the following Plantronics wireless headset systems:

  • CS500 series
  • Savi W700 series
  • Savi Office series
APC-41 EHS Cable
