Electronic Hookswitch HP APA-24 (Alcatel) — black, TAA-compatible

The HP Poly APA-24 (Alcatel) Electronic Hookswitch in black is a TAA-compatible accessory that provides electronic hook-switch control for compatible desk phones and headsets. Designed for use with supported Alcatel/HP telephony systems, this device enables remote answer and end call functions from a connected headset, improving hands-free call handling in office environments. The compact black unit connects inline between a headset and phone base to transmit the headset’s call-control signals to the telephone system.

Advantages

This electronic hookswitch offers reliable remote call control without modifying the desk phone. It supports seamless integration with compatible Alcatel/HP systems and works with standard headset connections to enable answer/end functions from the headset inline. The black finish is unobtrusive in office setups, and TAA compatibility ensures compliance with certain procurement requirements.
