Wireless Phone 9821, Bundle, Carbon Black

Introduction

The Cisco® Wireless Phone 9821 brings new power and flexibility to the 9800 Series, purpose-built for the fast-paced demands of frontline and mobile workers. Running on PhoneOS with Wi-Fi 6E, it delivers robust, secure business calling for both on-premises and cloud-based environments. Its shared-ready design—featuring swappable batteries and AI-driven noise removal—ensures reliable communication, keeping teams connected and productive even in the most challenging, high-noise settings.

With 72% of organizations relying on frontline workers, the 9821 is the essential tool for clinicians in healthcare, warehouse staff in manufacturing, and associates in retail and hospitality. The device is built to endure, featuring an IP54-rated, MIL-STD-8

10 tested exterior that resists dust, water, and shock. Its tactical, glove-friendly buttons ensure reliable operation in demanding environments, while safety is integrated into the core of the experience—with a dedicated action button, push-to-talk, and fall detection, staff have the rapid response capabilities they need to work with confidence.

For IT teams, the 9821 streamlines operations by integrating seamlessly into existing workflows through Zero Touch Provisioning and unified management via Cisco Control Hub. Beyond simplifying deployment and eliminating complex onboarding cycles, the device ensures enterprise-grade security with Transport Layer Security (TLS) 1.3 and Trusted Platform Module (TPM) 2.0. Because the phone is designed to function exclusively within your secure workplace infrastructure, it also acts as a natural deterrent against theft, providing IT with both peace of mind and comprehensive visibility across the entire fleet.
