The Cisco IP Phone 8851 is a business-class collaboration endpoint that combines high-fidelity, reliable, secure, and scalable voice over IP communications. The IP Phone 8851 combines an attractive new ergonomic design with wideband audio for crystal clear voice communications, “always-on” reliability, and encrypted voice communications to enhance security. This handset 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. Please note that this model is SIP ONLY not 'call manager' version.

Description

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.
