The Jabra HHC adapter works with your Jabra PRO 920 wireless headset, to enable remote answering on some Cisco IP phones.
This Electronic Hook Switch (EHS) means you will be able to answer telephone calls while away from your desk, without a handset lifter. You will hear the telephone ring in your wireless headset, then at the touch of a button you can answer the call.
This adapter is compatible with the following Cisco IP phones:
7942G, 7945G, 7962G, 7965G1, 7975G1
