​​What Is the CP-8861-K9=?​​

The ​​CP-8861-K9=​​ is a ​​Cisco IP conference phone​​ designed for ​​large meeting rooms​​ and auditoriums. Part of Cisco’s 8800 series, it features ​​360-degree audio capture​​ and ​​12 microphones​​, ensuring clear voice pickup for up to 20 participants. Unlike desk phones, it prioritizes ​​room-filling sound quality​​ and ​​seamless integration​​ with Cisco Webex and Unified Communications Manager (CUCM).

​​Key Features and Technical Advantages​​

• ​​12-microphone array​​: Eliminates “dead zones” in large spaces with ​​adaptive beamforming​​ technology.
• ​​Acoustic Fence​​: Automatically mutes ​​background noise​​ outside a defined meeting area.
• ​​PoE++ support​​: Powered via ​​802.3bt Ethernet​​ (90W), reducing cabling complexity.
• ​​HD voice and wideband codecs​​: Delivers ​​48 kHz audio sampling​​ for lifelike clarity.

​​CP-8861-K9= vs. Other Cisco Conference Phones​​

Compared to the ​​CP-8832-K9++=​​ (32-line desk conference phone), the ​​CP-8861-K9=​​ focuses on ​​spatial audio performance​​ rather than multi-line call handling. It also includes a ​​built-in 5-inch touchscreen​​ for simplified controls, a feature absent in the smaller CP-7821-K9.

​​Critical Technical Specifications​​

• ​​Codecs​​: G.711, G.722, G.729, and ​​AAC-LD​​ for low-latency audio.
• ​​Security​​: Supports ​​TLS 1.3​​, ​​SRTP​​, and ​​802.1X authentication​​ for secure deployments.
• ​​Compatibility​​: Works with ​​CUCM v12.5+​​ and ​​Cisco Webex Room Devices​​.
• ​​Certifications​​: ​​FCC Part 15​​, ​​CE​​, and ​​EN 55032​​ compliant.

​​Addressing Common User Concerns​​

​​Q: Can the CP-8861-K9= integrate with non-Cisco video conferencing systems?​​
A: Yes, via ​​SIP protocol​​, though advanced features like Webex controls require Cisco infrastructure.

​​Q: How difficult is the setup process?​​
A: ​​Plug-and-play​​ with CUCM auto-provisioning, but optimizing microphone zones may require ​​Cisco-certified technician support​​.

​​Q: Is the device suitable for hybrid meetings?​​
A: Absolutely—it pairs with ​​Webex Desk Pro​​ or ​​Room Kit​​ systems to bridge in-room and remote participants.

​​Practical Deployment Insights​​

In a recent installation for a university lecture hall, the ​​CP-8861-K9=​​’s ​​Acoustic Fence​​ proved invaluable in isolating speaker voices from ambient chatter. While its ​​lack of native Bluetooth​​ may frustrate some users, the ​​wired design ensures zero interference​​—a critical factor in high-stakes environments like courtrooms or boardrooms. For organizations scaling hybrid work, this phone bridges the gap between ​​simplicity​​ and ​​enterprise-grade performance​​, making it a cornerstone for modern collaboration spaces.
