The Cisco DP-9841-L-K9 is a Cisco Desk Phone 9841 in the First Light finish, part of the Cisco Desk Phone 9800 Series built for modern enterprise workstations. Running Cisco's PhoneOS software, it registers to a single platform of your choice — Cisco Unified Communications Manager (CUCM), Webex Calling, Webex Dedicated Instance, or Cisco BroadWorks — and supports up to 4 lines through 4 physical line keys, a backlit 3.5" grayscale display, and a wideband HD audio handset. It's powered over a single Gigabit Ethernet cable via PoE, with AI-based background noise removal keeping outgoing calls clear. This unit is Cisco Refresh — Cisco's own certified remanufactured program, in which genuine Cisco equipment is rebuilt and tested to Cisco's own quality standards before resale.

Cisco DP-9841-L-K9 - Key Features & Benefits

  • Gigabit PoE, Single-Cable Setup: An internal 2-port Gigabit Ethernet switch with PC pass-through runs on IEEE 802.3af PoE (Class 2) — no separate power adapter needed on a PoE-capable switch
  • AI-Enhanced Audio: AI-based Background Noise Removal on outgoing audio keeps the caller's environment out of the conversation, backed by Cisco HD Audio compliant with TIA-810/920 and ETSI ES 202 Security: Built-in TPM 2.0, Secure Boot, and TLS 1.3 protect the device and call signaling for security-conscious deployments

Cisco DP-9841-L-K9 - Frequently Asked Questions (FAQ)
  • What's the difference between the DP-9841-L-K9 and DP-9841-K9?
    Both are the same Cisco Desk Phone 9841 hardware and feature set — the L in DP-9841-L-K9 denotes the First Light finish, while DP-9841-K9 (no "L") is the standard Carbon Black finish. There's no functional difference between the two.
  • What phone systems does this register to?
    This phone is Interoperability Tested and Certified for Cisco Unified Communications Manager (CUCM) 12.5 or later, Webex Calling, Webex Dedicated Instance, and Cisco BroadWorks, and is also tested and certified for Asterisk. It's Microsoft SIP Gateway Compatible as well. Native CUCM support isn't available on every CUCM version, so a device package may be required.
  • How is this phone powered?
    IEEE 802.3af PoE (Class 2) over a single Ethernet cable from a PoE-capable switch — no separate adapter required. If your switch doesn't supply PoE, a Cisco Power Adapter 3 (sold separately, region-specific) can power the phone instead.
