Clearance items can be either customer returns in "like-new" condition (Open Box Items), unused inventory stock rotation, or manufacturer refurbished. All items are tested, quality assured, fully functional, and carry a full 90 day manufacturer's warranty.
The Plantronics EHS APV-63 Electronic Hook Switch for remote desk phone call control (answer/end) is recommended for use with the CS500 series headsets and the Grandstream GXP-2124 deskphone. This cable eliminates the need for a HL10 Handset Lifter.
We recommend consulting the manufacturer's telephone compatibility guide before purchasing headsets and accessories. Please find the guide here
