Part of the Cisco IP Phone 8800 Series, the 8861 combines a clear widescreen color display, programmable line keys, Gigabit Ethernet, Wi-Fi, Bluetooth and USB connectivity in a user-friendly desktop phone.
The Cisco IP Phone 8861 is suitable for businesses ranging from small and medium-sized offices to large enterprise environments that require dependable VoIP communication and flexible deployment options.
Clear and Professional Voice Communication
The Cisco CP-8861-K9 provides wideband audio and a full-duplex speakerphone for clear business conversations. Cisco also includes technologies such as acoustic echo cancellation, dynamic noise reduction, automatic gain control and voice-activity detection to improve the calling experience.
The phone supports multiple enterprise voice codecs, including G.711, G.722, G.722.2, G.729ab, iLBC, iSAC and Opus.
5-Inch Widescreen Color Display
The Cisco IP Phone 8861 features a 5-inch, 800 × 480 widescreen VGA color display with 24-bit color.
The display provides convenient access to calling features, directories, applications and other supported phone functions.
Five Programmable Line Keys
The CP-8861-K9 includes five programmable line and feature keys, allowing users to configure directory numbers, speed dials and other supported calling functions.
For users who need additional line or feature keys, the phone supports up to three Cisco IP Phone 8800 Key Expansion Modules, providing up to 108 additional keys.
Gigabit Ethernet Connectivity
The Cisco 8861 includes an integrated 10/100/1000 Ethernet switch, allowing the phone to connect to a Gigabit Ethernet network while also providing network connectivity for a co-located PC.
This makes it practical for office desks where both a computer and IP phone need network access.
Built-In Wi-Fi
The Cisco CP-8861-K9 supports 802.11a/b/g/n/ac Wi-Fi, providing an alternative to wired Ethernet connectivity in supported deployments.
Wireless connectivity can be particularly useful in offices where running an Ethernet cable to every workstation is difficult or where flexible desk arrangements are required.

The Cisco IP Phone 8861 supports Bluetooth for compatible wireless headsets and mobile-device integration.
It also provides two USB ports, which can support compatible headsets and charging for personal mobile devices.
Cisco Intelligent Proximity
Cisco Intelligent Proximity allows supported mobile devices to work more closely with the desk phone. Features include moving mobile-call audio to the IP phone and synchronizing supported call history and contacts.
Enterprise Security
The Cisco 8861 includes enterprise security features such as secure boot, credential protection, device authentication, configuration-file encryption and authentication, TLS signaling security and SRTP media encryption.
Power over Ethernet
The Cisco CP-8861-K9 supports IEEE 802.3af and 802.3at Power over Ethernet, allowing compatible network infrastructure to provide power and network connectivity through the Ethernet connection.
A separate Cisco power cube can be used for deployments where PoE is not available.
