Full Product Overview

The Cisco Desk Phone 9861NR, part number DP-9861NR-K9, is the No-Radio (NR) secure variant of the mid-upper tier Cisco Desk Phone 9861 enterprise IP desk phone within Cisco’s 9800 Series portfolio, built on unified cross-platform Cisco PhoneOS firmwareWebex.

Exclusive Hardware Difference vs Standard DP-9861-K9

Theonly hardware distinction:

• Standard DP-9861-K9: Equipped with rewritable NFC tag, dual-band Wi-Fi 802.11ac, Bluetooth 5.2 radio modules for wireless headsets, mobile contact sync and NFC zero-touch provisioning.
• DP-9861NR-K9 (No-Radio Variant): All wireless radio hardware is fully removed from the PCB –no NFC tag, no Wi-Fi radio, no Bluetooth radio; every other telephony hardware, port, display, keypad, audio processing, PoE budget, KEM expansion compatibility and PhoneOS feature set are identical to the standard wireless model.

Core Positioning & Hardware Tier Comparison
