The Cisco CP-8861-K9 is a desktop IP phone engineered for business-class voice communications, featuring a 5-inch WVGA color backlit LCD display with 800 × 480 pixel resolution that delivers clear visibility of call information, menus, and applications. This endpoint combines 5 programmable line keys with dual-color LED indicators (green/red), 4 soft keys, and 12 fixed feature keys to streamline call handling and feature access. The device supports wideband HD voice across handset, speakerphone, and headset modes, with full-duplex speakerphone technology and acoustic echo cancellation for superior audio clarity. Connectivity is robust: dual RJ-45 Gigabit Ethernet ports (10/100/1000 Mbps) enable both LAN and PC passthrough, while an RJ-9 analog headset port and USB Type-A port accommodate traditional and modern headset options. The CP-8861-K9 supports IEEE 802.3af Power over Ethernet (Class 3), though an optional Cisco CP-PWR-CUBE-4 external power adapter may be required depending on deployment configuration.

Network engineers and IT procurement teams managing Cisco Unified Communications Manager (UCM) or Cisco Webex Calling environments select the CP-8861-K9 to deliver standards-compliant, secure voice services to knowledge workers. The phone implements SIP and SCCP protocols alongside industry-standard codecs—G.711, G.722, G.729a, iLBC, and iSAC—ensuring interoperability and bandwidth flexibility. Wireless capability via IEEE 802.11a/b/g/n/ac (dual-band 2.4 GHz and 5 GHz) provides deployment flexibility, backed by WPA2-Personal and WPA2-Enterprise security (EAP-FAST, EAP-TLS, EAP-TTLS, PEAP) alongside IEEE 802.1X authentication, SRTP media encryption, and TLS signaling encryption for comprehensive security posture. The device operates reliably across standard office environments, with an operating temperature range of 0°C to 40°C.

Whether you are standardizing voice infrastructure across multiple sites or expanding capacity in an existing Cisco telephony deployment, the CP-8861-K9 delivers the feature density and reliability enterprises require.
