The Polycom Headset Hook Switch Control Adapter can be used as an alternative to the HL10 lifter.
The Polycom Headset Hook Switch Control (APP-5) adapter transforms the Polycom Unified IP phone experience by extending the advantages of Plantronics professional wireless headset systems.
- Always be aware of incoming calls - even when away from their desk - with the headset ring alert.
- Freedom to move around the office and accept and end calls from wherever they are with their wireless headset call control button.
- Direct connection to their Polycom SoundPoint IP phone, which eliminates the need for a mechanical handset lifter device.
