Cisco Desk Phone 9861 DP-9861NR-K9 - No Radio 10-Line VoIP Phone, 5-Inch Color LCD, Gigabit PoE, PhoneOS - Cisco Refresh

The Cisco Desk Phone 9861 (DP-9861NR-K9) is the No Radio variant of Cisco's premium 9800 Series 10-line VoIP desk phone, built for secure enterprise environments where wireless radios must be absent at the hardware level — government, defense, finance, and healthcare deployments. It pairs a 5-inch backlit color LCD (800 x 480) with 10 physical line keys, Cisco HD wideband audio, and Cisco Smart Audio noise removal. Running Cisco PhoneOS, a single device registers to Cisco Unified Communications Manager (CUCM) 12.5 or above, Webex Calling, Webex Dedicated Instance, or Cisco BroadWorks. Connectivity is wired only via a 2-port Gigabit Ethernet switch with IEEE PoE Class 3 power.

Cisco DP-9861NR-K9 - Key Features & Benefits

• No Radio Hardware Variant: Ships without Wi-Fi, without Bluetooth, and without NFC, meeting the wired-only policy requirements common in government, defense, financial, and healthcare networks. All other 9861 capabilities are unchanged from the standard model.
• 10 Physical Line Keys, Expandable: Ten backlit physical line keys handle busy call flows directly. With Cisco Desk Phone 9800 Key Expansion Modules the phone scales to a maximum of 130 line and programmable line keys — that figure requires three KEMs plus the Cisco Power Adapter 3 and applies on CUCM and Webex Dedicated Instance. Capacity varies by calling platform.
• 5-Inch Color LCD with Cisco PhoneOS: A 5-inch backlit 800 x 480 color display paired with a 4-way navigation key, a dedicated calendar button, and a customizable Action button that can be configured for emergency alerts, paging, or other administrator-defined actions.
• Cisco Smart Audio with Noise Removal: Delivers Cisco HD wideband audio through a full-duplex speakerphone and a wideband-capable handset. Cisco Smart Audio provides conventional and AI based background noise and voice removal for the sending side and conventional and AI based background noise removal for the receiving side.
• Single-Cable Gigabit PoE Deployment: An internal 2-port 10/100/1000BASE-T Ethernet switch (IEEE 802.3i/802.3u/802.3ab) shares one drop between the phone and a co-located PC, powered by IEEE Power over Ethernet Class 3 with 802.1Q VLAN separation for voice and data traffic.
• Hardware-Rooted Enterprise Security: Built on Trusted Platform Module (TPM) 2.0 with Secure Boot, image authentication, TLS 1.3 signaling encryption, SRTP media encryption, 802.1X with custom device certificate, Secure Unique Device Identifier (SUDI), and Security-Enhanced Linux.

Cisco DP-9861NR-K9 - Frequently Asked Questions (FAQ)

• What is the difference between DP-9861NR-K9 and DP-9861-K9?
  The NR (No Radio) variant ships without Wi-Fi, Bluetooth, and NFC hardware, while the standard DP-9861-K9 includes Wi-Fi CERTIFIED 802.11a/b/g/n/ac dual-band and Bluetooth 5.2. Display, 10 line keys, audio, Gigabit Ethernet, and PoE are otherwise identical — choose NR when wireless radios are prohibited by policy.
• Which calling platforms does this phone work with?
  Cisco lists the 9800 Series as interoperability tested and certified for Cisco Unified Communications Manager (CUCM) 12.5 or above, Webex Calling, Webex Dedicated Instance, and Cisco BroadWorks. It may interoperate with other SIP platforms, though additional configuration can be required, and native CUCM support is not available on every version — a device package may be needed.
• How is the phone powered, and can I connect a Key Expansion Module?
  It draws power over the network via IEEE Power over Ethernet Class 3, or from the optional Cisco Power Adapter 3 (sold separately). Under PoE Class 3 the USB-A port supports one Cisco Desk Phone 9800 KEM; with the Cisco Power Adapter 3 you can drive up to three KEMs.
