Note: Jabra recommends that you upgrade to the newer version of this cable - Use the new EHS adapter # 14201-43.
Jabra EHS #14201-16, for Cisco allows you to Go farther… do more! The Cisco Headswitch Headset Control (HHC) enables Electronic Hookswitch (EHS) functionality to work with Cisco 7900G phones manufactured after September 2007. Simply "plug and play" to hear ring tones, answer and end calls, adjust volume, or even mute calls from your headset's integrated controls, all up to 300 feet away from your phone! Use with Jabra wireless headsets.
The Cisco HHC EHS converts from the HHC standard used in Cisco phones to the DHSG standard used in Jabra headsets — and vice versa — to allow you to maximize the benefits of both your wireless headset and Cisco Unified IP phone for expanded efficiency and productivity.
