The Plantronics APV-63 is an electronic hookswitch (EHS) cable for Avaya desk phones and may work with additional manufacturers. The APV-63 is designed for use with Plantronics headsets in the Savi 700 series, Savi Office series and CS500 series.

 

The Plantronics APV-63 EHS cable allows you to take calls and end calls by the push of a button on your Plantronics headset even when you are not within arms range of the phone, eliminating the need for a HL10 Handset Lifter.
