The Plantronics Spare EHS 3.5MM Cable is an Electronic Hook Switch (EHS) cable for Panasonic Phones. This cable communicates electronically with the phone, eliminating the need for the HL10 lifter. The SAVI W700 or the CS500 series headsets can be used with certain Panasonic SIP phones with this cable.
It works with select Panasonic KX-DT, KX-NT and KX-UT phones.
