Poly APP-51 Electronic Hook Switch Cable

The Poly 85Q60AA is an electronic hook switch cable that links a compatible Poly desk phone with a Poly headset, giving you one-button control over incoming and outgoing calls. By moving call management to the headset, it removes the need for a mechanical handset lifter and keeps your desktop uncluttered.

Installation is straightforward: connect the cable between the phone’s interface port and your headset base, follow the short pairing process described in the phone’s menu, and you are ready to take or end calls without touching the handset. The cable works with the Plantronics Online Indicator, so people nearby can see when you are on a call and choose the right moment to interrupt.

This model replaces the earlier APS-50, broadening compatibility to newer Poly desk phones while retaining the dependable audio and signaling your team expects. Because the cable is light and flexible, it fits neatly into workstations where space is tight, such as shared hot-desking areas or reception counters.

Whether you support a busy help desk, run back-to-back client meetings from a private office, or handle customer care from a remote setup, the Poly 85Q60AA helps you stay productive. With reliable remote call control, you can step away from the phone to grab a file, refill a coffee, or simply keep your posture natural, all while staying ready to respond at a tap of the headset button.

Highlights:

• Directly connects a Poly headset to compatible Poly desk phones for seamless call control
• Lets you answer and end calls from the headset’s call button, eliminating a separate handset lifter
• Supports the Plantronics Online Indicator so coworkers can see when you are busy
• Replaces the APS-50 and widens compatibility with current Poly phone models
• Lightweight construction that minimizes cable clutter and installs in minutes
