Designed for remote desk phone call control (answer/end), the APP-51 Electronic Hook Switch Cable from Poly eliminates the need for a HL10 Handset Lifter. It connects to your Poly headset and allows you to answer and end calls using the headset call control button. It works with Poly desk phones as well as phones from other manufacturers, but please ensure compatibility before purchasing.
Note: The APP-51 EHS cable replaces the APS-50 cable and is compatible with the Plantronics Online Indicator accessory.
