It enables electronic hook-switch control so calls can be answered and ended directly from the headset. The black cable is designed for straightforward installation without additional configuration.

Users needing EHS on supported Cisco models

The cable suits professionals who want remote call handling on their existing Cisco handset. Buyers whose phone system uses a different EHS standard or lacks an EHS port will not be able to use this adapter. Those requiring Bluetooth or DECT pairing without a wired link should consider alternative solutions.
