Overview of Cisco 8845 IP Phone (CP-8845-K9) | New


The Cisco 8845 IP Phone (CP-8845-K9) can help you boost personal productivity by providing strong and simple-to-use user experiences. It blends an appealing new ergonomic design with 720p HD video and wideband audio for crystal-clear video and voice communications and "always-on" reliability. The 8845 encrypts video and phone communications for security and provides access to a comprehensive array of unified communications services.

Furthermore, when you use your mobile device at your desk for work, Cisco Intelligent Proximity combines the worlds of desk and mobile for you. During active mobile calls, you can shift the audio path to the 8845 to take advantage of its improved audio acoustics. Sharing a chat with a colleague who is listening in is one example. This feature allows you more freedom at your workplace.

The Cisco 8845 IP Phone includes five configurable line keys. You can arrange keys to support either numerous directory numbers or call capabilities such as rapid dial. You can also increase efficiency by processing several calls for each directory number by utilizing the multicall-per-line capability. Fixed function keys provide one-touch access to programs, messaging, and the directory, as well as frequently used calling capabilities like hold/resume, transfer, and conference. Backlit acoustic keys allow for greater audio path choices and switching.
