83017-01 - APU-7 EHS Electronic Hook Switch Cable for Cisco/Nortel:

Electronic Hook Switches (EHS) communicate electronically with your phone giving your wireless headset answer/end and ring alerts remotely.  The use of an EHS cable eliminates the need for an HL10 handset lifter. 

Plantronics has several EHS adapters, each being unique to a specific telephone and wireless product.  We strongly suggest confirming compatibility with us before purchasing.
