Plantronics APD-80 Electronic hookswitch EHS Cable for use with CS500-Series wireless headset and all Savi wireless headset models (CS540, CS510, CS520, CS530, WO100, WO200, WO350, W730, W740, W710, W720, W730, Voyager Legend CS), when connected to the Grandstream GXP-2124, GXP-2130, GXP-2140, GXP-2160, Shoretel IP 480, 480G, 485 and Verizon Landmark LM416.
This device allows the user to answer and end calls from the headset remotely while away from the desk by simply pressing the talk button on the earpiece. An audible beep tone is provided in the earpiece to alert the user to an incoming call. The call answer/end function is all electronic (rather than mechanical as it is with the HL10 handset lifter). No lifter is needed!
IMPORTANT: For the Grandstream models listed above, you will also need an adapter extension cord in order for the EHS cord to reach the necessary port (part 85638-01). Please see below.
Please feel free to call us if you are unsure which EHS (electronic hookswitch) is right for your phone. Part 87327-01. Covered by 1 year factory warranty.
