Plantronics APC-82 EHS Cable for Cisco Phones

Plantronics APC-82 EHS Cable for Cisco IP Phones

The Plantronics APC-82 EHS Cable is a dedicated Electronic Hookswitch (EHS) cable that enables remote call control between your Plantronics headset and compatible Cisco IP desk phones. If you’re tired of manually lifting the handset every time a call comes in, this simple cable lets you answer, end, and mute calls directly from your wireless headset – no bulky mechanical handset lifter needed. Designed for a wide range of Cisco 7800 and 8800 series phones, the APC-82 connects directly to the phone’s auxiliary port (AUX) and to your Plantronics headset base. Setup is plug‑and‑play: connect, and you’re ready to enjoy true hands‑free efficiency.

How It Works

The APC-82 cable connects to your Cisco phone’s RJ9 or RJ45 auxiliary port (check your phone model; typically the AUX port on the back) and to your Plantronics headset base (such as the CS500 series, Savi 700 series, or Voyager Focus UC base) using the included connectors. Once installed, the cable transmits electronic hookswitch signals between the phone and the base. When you press the call control button on your headset, the base tells the phone to go off‑hook – exactly as if you had lifted the handset. Press again to end the call; the phone will hang up automatically. The cable also supports mute and volume adjustments from your headset. No external power supply is needed; the APC-82 is a passive cable that draws minimal power from the phone. For a complete wireless office experience, pair this EHS cable with a high‑quality wireless headset – explore our selection at FindHeadsets for Plantronics and Poly models that are fully compatible.

Why Choose This Product

Without an EHS cable, using a wireless headset with a Cisco IP phone requires either manually lifting the handset or using a mechanical handset lifter. The APC-82 is a much cleaner, more reliable solution. It provides true electronic hookswitch control: answer, end, and mute directly from your headset. It also improves audio quality because the signal stays electronic rather than passing through a mechanical connection. For call center agents, busy executives, or anyone taking many calls daily, the time saved and reduced motion strain add up significantly. Plus, it keeps your desk tidy and professional. This cable is specifically optimized for Cisco phones, ensuring flawless operation with no additional configuration.
