The Cisco^®IP Phone 8851NR is a business-class collaboration endpoint that combines high-fidelity, reliable, secure, and scalable voice over IP communications without Bluetooth radio.

With the Cisco IP Phone 8851NR, you can increase personal productivity through an engaging user experience that is both powerful and easy to use. The IP Phone 8851NR 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 on-premises and hosted infrastructure platforms. The 8851NR (non-radio) model is for customers who still wish to have HD audio with flexibility to add Key Expansion Module (KEM) support but without integrated Bluetooth radio.

The IP Phone 8851NR 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 IP Phone 8851NR 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, and 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.
