## Long description

APP-51 Electronic Hook Switch (EHS) cable for Poly desk phones, model 38439-11. The cable enables remote call control — answer and end calls — directly from a compatible headset, removing the need for a mechanical handset lifter. It is designed for use with Poly desk phones and may also be compatible with other manufacturers' telephones. The APP-51 EHS replaces the older APS-50 cable and adds compatibility with the Plantronics On-line Indicator accessory.
Advantages
The Poly 38439-11 EHS cable provides hands-free call control, durable construction for reliable daily use, and straightforward connectivity with compatible Poly headsets and phones. By eliminating the handset lifter, it simplifies desk setup and reduces moving parts that can wear out. Backward compatibility with the APS-50 function and support for the Plantronics On-line Indicator increase flexibility in mixed equipment environments.
Suitable for (tasks / use cases)
Office desk phones where headset-based call answer/end is required
Contact centers and reception desks needing hands-free call handling
Users replacing an APS-50 cable with improved compatibility
