Plantronics Voyager 4200 UC Series makes it easy to switch between PC/Mac and mobile devices, so it’s easy to stay connected. A dedicated button gives you quick access to mute, while voice prompts alert you if you’re on mute when you start talking. Enhanced voice alerts tell you connection status, remaining talk time, mute status and more. Your colleagues will know when you’re talking to someone because of the red call indicator light. And, you’ll still hear incoming calls if you step away from your desk.
