Poly APS-11 APS-11 Electronic Hook Switch Cable

The Poly 85Q78AA is the APS-11 Electronic Hook Switch Cable that gives you direct control over desk phone calls from your compatible Plantronics headset. Instead of rushing back to your phone every time it rings, you can answer or end conversations with a tap on the headset, even when you are a few steps away.

This cable sends electronic hook switch signals between the phone and the headset base, so no mechanical handset lifter is required. The result is a quieter workspace, fewer moving parts on your desk, and call handling that feels smooth and reliable.

Compatibility is broad. The APS-11 supports many Siemens desk phone models and additional brands that follow the same EHS standard. On the headset side, it works with the Plantronics Savi 700 Series, C5500 Series, MDA200, and Savi Office Series. If you are upgrading from the APS-10, the APS-11 is the current replacement and it adds support for the Plantronics On-line Indicator, which lights up to show colleagues you are busy.

Sales professionals, customer support agents, and anyone who spends the day on the phone will appreciate the freedom to grab a file, stretch, or step away from the desk without missing a call. The cable is TAA compliant, making it a safe choice for government or regulated environments where that certification is mandatory.
