Poly APC-43 EHS Electronic Hook Switch Cable

The Poly 85Q55AA is an Electronic Hook Switch cable that lets you answer or end calls on compatible Cisco desk phones without using a separate handset lifter. By linking the phone to a supported Poly headset base, you gain one-touch call control that keeps conversations smooth and desks clear.

The cable works seamlessly with popular Cisco models such as the 7821, 7841, 8841, and 8851. It also operates when an expansion module is attached, so receptionists and power users can enjoy the same effortless control even with extra line keys in place.

This solution is ideal for anyone who spends long stretches on the phone. Customer service teams can take notes while talking, office staff can step away to grab documents, and remote workers can maintain a tidy home setup without extra hardware cluttering the space.

The cable itself feels light in weight and compact in size, so it blends easily with existing cords and needs no external power. Installation takes only a few minutes, and once it is in place you can rely on consistent, reliable call control throughout the day.
