HP APC-43 Cisco Electronic Hook Switch Cable

Connect a compatible Cisco desk phone to a supported headset system for electronic hook-switch control. The APC-43 cable carries the call-control connection needed to answer and end calls remotely, so users can operate calls from a headset rather than reaching for the telephone handset. It replaces the separate handset-lifter approach used where no electronic hook-switch interface is present. Install the cable as a direct accessory between the desk phone and headset equipment, then use the headset’s supported call-control functions for everyday voice work. This arrangement suits fixed desks, shared reception positions, contact-center stations and other locations where a Cisco phone remains the primary call endpoint. The black cable is supplied as one unit for phone connectivity. HP 38350-13 corresponds to the Poly APC-43 Cisco electronic hook switch cable. Its role is specific: it provides an electronic answer/end-call interface for compatible Cisco desk phones, rather than adding audio ports, network connectivity or a handset. Select it when the phone and headset equipment support the required EHS connection.
