The Cisco CP-8821-K9 is a professional-grade wireless IP phone engineered for enterprise mobility. Designed to keep workers connected across large facilities and campuses, this handset operates over 802.11 Wi-Fi networks and integrates natively with Cisco Unified Communications Manager (CUCM), delivering the same feature-rich experience as a desk phone — without the tether.Built with the needs of healthcare, hospitality, manufacturing, and higher education environments in mind, the 8821 supports push-to-talk, Bluetooth headset connectivity, and a long-lasting battery suitable for extended shifts. Its intuitive interface mirrors the familiar Cisco IP phone experience, reducing training time and accelerating adoption across large teams.
This refurbished unit has been inspected and tested to ensure full operational functionality, offering enterprise reliability at a fraction of the cost of new hardware. WhaleyComm sources refurbished Cisco equipment to help IT teams maximize budget without compromising on quality or performance.
Key highlights include a color display, support for multiple lines, and compatibility with Cisco's broader UC ecosystem including CUCM and Cisco Unified Communications Manager Express (CME). The CP-8821-K9 is the base model in the 8821 series and does not include a battery charger in the base configuration — making it ideal for organizations already standardized on the 8821 platform seeking to expand their fleet cost-effectively.
