About the Cisco CP-8841-K9 IP phone / endpoint
As a critical hardware component requiring rapid replacement in production voice environments, the Cisco CP-8841-K9 IP phone demands a reliable supply chain partner. This endpoint from Cisco's IP Phone 8800 Series delivers enterprise-grade calling functionality through a compact desktop form factor. The device features a 5-inch grayscale backlit LCD with 800 x 480 pixel resolution, paired with 5 programmable line keys and 5 context-sensitive softkeys for intuitive call management. The CP-8841-K9 supports dual RJ-45 Gigabit Ethernet ports (10/100/1000 Mbps)—one for LAN uplink and one for PC passthrough—enabling flexible network integration. Power delivery via IEEE 802.3af Power over Ethernet (PoE) runs at approximately 5 W idle to 7 W active, with optional external supply via the CP-PWR-CUBE-4 for demanding deployments.
Network engineers and IT procurement teams standardizing on Cisco unified communications select this model for its dual call control compatibility with Cisco Unified Communications Manager (UCM) and Cisco Webex Calling. The phone operates on SIP protocol and delivers HD Voice through wideband audio codecs including G.711, G.722, G.729, and iLBC, ensuring crystal-clear conversations across the enterprise. Security is hardened through 802.1X port authentication, TLS signaling encryption, and SRTP media encryption, while IEEE 802.1Q VLAN tagging and voice VLAN support enable segmentation in complex network topologies. Quality of Service is managed through IEEE 802.1p and DSCP marking. Dual headset connectivity—RJ-9 analog port and USB Type-A—accommodates diverse peripheral requirements, and full-duplex speakerphone operation supports collaborative environments. Operating across 0°C to 40°C (32°F to 104°F), the device integrates reliably into standard office and data center conditions.
