Key Features of Cisco CP-8861-K9

Five Programmable Line and Feature Keys

The Cisco CP-8861-K9 includes five programmable line and feature keys that help users manage multiple communication functions from a single desktop device. These keys can be configured for supported lines, speed-dial functions, or other call-management features, making the phone suitable for employees who handle several calls or frequently access specific contacts and services.

High-Resolution Color Display

The integrated 5-inch color display offers an 800 × 480-pixel resolution and a 24-bit color depth. This provides a clear and accessible interface for viewing caller information, call status, menus, directories, and other supported phone functions. The display is designed to improve day-to-day usability in professional office environments.

Wideband Audio and Clear Voice Communication

The Cisco 8861 supports wideband audio and multiple voice codecs for compatible Cisco collaboration deployments. Supported codecs include G.711 A-law and μ-law, G.722, G.722.2, G.729ab, iLBC, iSAC, and Opus. Codec availability and actual audio performance depend on the configured platform, firmware, network, and call environment.

Gigabit Ethernet Connectivity

The phone includes an integrated 10/100/1000 Ethernet switch, allowing the device to connect to a Gigabit Ethernet network while providing a downstream network connection for a compatible computer. This design can help reduce cable requirements at the workstation and simplify network connectivity in office deployments.

Integrated Wi-Fi Support

The CP-8861-K9 supports 802.11a/b/g/n/ac wireless networking for compatible deployments. Integrated Wi-Fi provides additional flexibility for organizations that want to deploy IP phones in locations where traditional wired network connectivity may be limited or where wireless installation is preferred.

Bluetooth and USB Accessory Support

Bluetooth 3.0 Enhanced Data Rate support allows compatibility with supported Bluetooth accessories and mobile integration features. The phone also includes two USB ports for compatible accessories and supported device functions. Actual accessory compatibility depends on the phone firmware and the Cisco collaboration platform in use.

Power over Ethernet Support

The Cisco CP-8861-K9 supports IEEE 802.3af and IEEE 802.3at Power over Ethernet standards and is classified as PoE Class 4. This allows the phone to receive power through a compatible network connection, helping reduce the need for a separate power adapter in supported network installations.

Technical Specifications

Compatibility and Licensing

The Cisco CP-8861-K9 is intended for use with supported Cisco collaboration platforms and compatible Cisco Unified Communications environments.
