Electronic Hook Switch Cable for remote desk phone call control (answer/end). This cable eliminates the need for a HL10 Handset Lifter. This cable works with a variety of desk phones (Unify, Funwerk, Auerswald, Agfeo, Aastra, DTeWe) and may work with additional manufacturers. Replacement Note: The APS-11 EHS cable replaces the APS-10 cable and features compatibility with the Plantronics On-line Indicator accessory.
