What Is the Cisco CP-8851-K9 IP Phone?

The Cisco CP-8851-K9 is a professional business VoIP phone engineered for knowledge workers, administrative assistants, and executive managers who require enhanced peripheral flexibility alongside traditional telephony features. By combining enterprise-grade security with modern wireless capabilities like Bluetooth, it delivers an adaptable communication hub designed for modern office productivity.

Its ergonomic design reduces physical fatigue during long corporate hours, while context-sensitive soft keys and programmable line options provide immediate access to essential call management functions without navigating complex software menus.

Bluetooth Integration and Enhanced Mobility

A standout capability of the Cisco CP-8851-K9 is its native Bluetooth 3.0 radio support. This functionality allows professionals to connect compatible wireless headsets directly to the phone, granting complete freedom of movement around the office space during active calls.

Furthermore, users can pair their smartphones with the desk phone. When a mobile call arrives, it can be routed directly through the Cisco IP phone audio path, or mobile contacts can be synchronized for easy office dialing, bridging mobile and desktop communication workflows seamlessly.

Brilliant 5-Inch Display and Interface Usability
