The Agent EHS cable for Avaya 1400, 1600 and 9600 works in conjunction with the Agent wireless DECT headsets. It offers remote operation of your Avaya deskphone (1400, 1600 or 9600 series), eliminating the need for a mechanical handset lifter. This offers you the freedom to move around the office but still be able to answer calls while you are away from your desk.
