The Jabra Supervisor Cord connects two Jabra Quick Disconnect headsets to the desk phone, so that supervisor resources can be deployed easily to manage more complex customer conversations or for training purposes. The supervisor’s microphone can be turned on or muted using the mute button integrated in the cable’s supervisor interface. Primarily for desk phones; also works with softphones via LINK 2X0. For new softphone deployment, Jabra recommends the LINK 265 USB Supervisor Solution.
