Poly APC-45 EHS Cisco
For modern Plantronics/Poly Headsets with Cisco SPA models 512, 514, 525G
A wireless headset is a great invention, so why complicate things with mechanical handset lifters? This baby will enable you to answer calls from anywhere with your wireless headset (provided you don't stray more than 100m from your phone so don't get too carried away).
Poly APC-45 is compatible with the following wireless headsets:
Always be aware of incoming calls, even when away from your desk, with the headset ring alert.
Freedom to move around the office and accept and end calls from wherever you are with your wireless headset call control button.
Connect an (optional) On-line Indicator so that people know when you are on a call.
