Poly RD-1 Electronic Hook Switch Cable

The Poly 85R71AA is an electronic hook switch cable that lets you control calls from a compatible Poly wireless headset without reaching for the phone handset. By connecting the cable between your deskphone and headset base, you can answer or end calls at the press of a button on the headset itself. Incoming call alerts reach your ear instantly, so you can step away from your desk and still pick up before the caller hangs up.

This simple add-on is a practical upgrade for anyone who spends the day on the phone, from customer service agents to managers who jump between meetings and calls. It pairs smoothly with Poly CS50, CS60, CS70, and Voyager 510S models, so setup takes only a few minutes and no extra lifter hardware is required. The cable’s design is compact and finished in black, so it keeps a low profile on crowded desks while standing up to daily bending and plugging.

With physical dimensions of 13.39 by 9.06 by 2.76 inches, the RD-1 fits easily alongside your phone base or within a cable tray. Once installed, it streamlines call handling, reduces desk clutter, and helps ensure you never miss a call when you step away for a file or coffee.
