The Cisco
®
IP Phone 8851 is a business-class collaboration endpoint that combines
high-fidelity, reliable, secure, and scalable voice communications with Cisco Intelligent
Proximity for telephony integration for personal mobile devices to support midsize to
large enterprise businesses.
With the Cisco IP Phone 8851, you can increase personal productivity through an engaging user experience that is
both powerful and easy-to-use. The IP Phone 8851 combines an attractive new ergonomic design with wideband
audio for crystal clear voice communications, “always-on” reliability, encrypted voice communications to enhance
security, and access to a comprehensive suite of unified communication features from Cisco communication
servers.
In addition, Cisco Intelligent Proximity brings the worlds of desk and mobile together for you when you are using
your mobile device at the desk for your work. You can move the audio path over to the Cisco IP Phone 8851 during
active mobile calls to take advantage of its superior audio acoustics. An example would be to share a conversation
with a colleague who you want to listen in. This capability gives you greater flexibility and a superior user
experience when at your desk.
The IP Phone 8851 also comes standard with a USB port so you can charge your smartphone when at your desk,
and stay connected when away from your desk.
The Cisco IP Phone 8851 offers five programmable line keys. You can configure keys to support either multiple
directory numbers or calling features such as speed dial. You can also boost productivity by handling multiple calls
for each directory number using the multicall-per-line feature. Fixed-function keys give you one-touch access to
applications, messaging, directory, as well as often-used calling features such as hold/resume, transfer, and
conference. A five-way navigation cluster helps you transition through menus more easily. Backlit acoustic keys
provide flexibility for audio path selection and switching.
