Running Cisco PhoneOS, the 9851 supports Cisco Unified Communications Manager (CUCM 12.5+), Webex Calling, Cisco BroadWorks, and 3rd Party Call Control (3PCC) platforms, all configurable without changing hardware.

AI-based Background Noise Removal (BNR) on the outgoing side reduces distractions, while Cisco HD audio and a bass-enhancing acoustic enclosure deliver full-duplex speakerphone clarity. HAC-compliant handset supports hearing aid users. Dual Gigabit Ethernet (10/100/1000) with PC pass-through, USB-A and USB-C headset ports, and PoE 802.3af power provide flexible connectivity. USB-C also charges a connected device when using the optional AC adapter (sold separately). TPM 2.0, TLS 1.3, SRTP, Secure Boot, and Image Authentication secure every call. ENERGY STAR certified; over 74% post-consumer recycled plastic. Includes: phone, handset, cord, desk stand, Ethernet cable. Power adapter not included.
- AI Background Noise Removal & Cisco HD Audio: Cisco AI-based Background Noise Removal (BNR) filters outgoing audio to reduce distractions, ensuring the far-end caller hears you clearly. Full-duplex speakerphone uses a larger driver and bass-enhancing acoustic enclosure for natural-sounding voice quality. Cisco HD audio is TIA-810/920 compliant with AEC (Echo Cancellation), AGC (Gain Control), and PLC (Packet Loss Concealment) for clarity on any network.
- 6 Physical Line Keys | Up to 46 Programmable Keys: Six physical line keys with tri-color LED indicators give instant visual status for calls and messages.

- One Platform: CUCM | Webex Calling | BroadWorks | 3PCC: Cisco PhoneOS lets one device register to CUCM (12.5+), Webex Calling, Cisco BroadWorks, or 3rd Party Call Control (3PCC) platforms including Asterisk and hosted SIP providers — no hardware swap needed. Simplifies procurement, deployment, and training. One Button to Push (OBTP) enables instant meeting join from the phone screen on Webex Calling or CUCM. Native desk reservation and hot desking supported.
- Dual Gigabit PoE Ethernet + USB-A & USB-C Headset Ports: Dual-port 10/100/1000 Gigabit Ethernet with PC pass-through shares one network drop between phone and computer.
