Plantronics APD-80 Electronic Hookswitch for Grandstream 2124 Phone

Plantronics APD-80 – Electronic Hookswitch for Grandstream GXP2124 Phone

The Plantronics APD-80 is an Electronic Hookswitch (EHS) adapter designed specifically for the Grandstream GXP2124 enterprise IP phone. If you use a Plantronics wireless headset with this Grandstream model and are tired of manually lifting the handset every time you answer a call, this small adapter is the solution. It enables true remote call control – answer, end, and mute calls directly from your headset – without the need for a bulky mechanical handset lifter. Setup is plug‑and‑play: connect the adapter between your Grandstream GXP2124 and Plantronics headset base, and you’re ready to enjoy hands‑free efficiency.

How It Works

The APD-80 connects to your Grandstream GXP2124 phone’s dedicated RJ9 headset port and to your Plantronics headset base (such as the CS500 series, Savi 700 series, or Voyager Focus UC base) using the included RJ9 cable. Once installed, the adapter translates the phone’s electronic hookswitch signals. When you press the call control button on your headset, the adapter tells the phone to go off‑hook – exactly as if you had lifted the handset. Press again to end the call, and the phone hangs up automatically. The adapter also supports mute and volume adjustments from your headset. No external power supply is needed – the APD-80 draws power directly from the phone’s headset port. For a complete wireless office experience, pair this EHS adapter with a high‑quality wireless headset – explore our selection at FindHeadsets for Plantronics and Poly models that are fully compatible.

Compatibility & Design

The Plantronics APD-80 is specifically designed for the Grandstream GXP2124 phone. It also works with some other Grandstream models that use the same EHS interface (check your phone’s compatibility). It is compatible with Plantronics headset bases that feature an EHS port, such as:

Plantronics CS500 series (CS510, CS520, CS530, CS540)

Plantronics Savi 700 series (W710, W720, W730, W740)

Plantronics Voyager Focus UC base

The adapter is compact (approx. 2 x 1.5 x 1 inches) and sits discreetly between your phone and headset base. It includes a short RJ9 cable. The unit is black with a small status LED. No drivers or software are required – it’s pure plug‑and‑play.

Why Choose This Product

Without an EHS adapter, using a wireless headset with a Grandstream GXP2124 forces you to either manually lift the handset or use a mechanical handset lifter. The APD-80 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 adapter is specifically optimized for the Grandstream GXP2124, ensuring flawless operation.
