Poly APS-11 EHS Cable | Siemens/Aastra – 85Q78AA

Product Overview

The Poly APS-11 EHS Cable (85Q78AA) enables electronic call control between compatible Poly wireless headsets and Siemens, Aastra, Mitel, and Unify desk phones. This Electronic Hook Switch cable allows users to answer and end calls directly from their headset without physically interacting with the desk phone, eliminating the need for a mechanical HL10 Handset Lifter.

The APS-11 sends ring alert signals to your headset anywhere within wireless range, so you never miss a call while away from your desk. Compatible with Poly CS500 series and Savi series wireless headsets, this cable replaces the legacy APS-10 and adds compatibility with the Poly On-Line Indicator (OLI) accessory for visual call status.
