CP-7841-K9 Overview
CP-7841-K9 is the Cisco IP Phone 7841, a desk handset in the Cisco 7800 Series built for four-line user positions that need Gigabit pass-through at the workstation. The model sits between the two-line 7821 and the sixteen-line 7861, using a backlit grayscale display rather than the smaller entry 7811 display and keeping the familiar fixed call-control layout of the family. It registers to Cisco on-premises and hosted calling environments or supported third-party hosted call control, so service depends on the configured voice platform and assigned user profile. Power comes from IEEE 802.3af Class 1 PoE, with Cisco Power Adapter 3 available for non-PoE desks. The charcoal 7841 hardware row includes the default replaceable black bezel, with a silver bezel available separately. Cisco 7861 changes the same family position with sixteen line keys instead of this model's four.
G.711, G.722, G.722.2, G.729ab, iLBC, and OPUS codec support carries handset, headset, and speakerphone audio across SIP voice deployments. A 3.5 inch 396 x 162 pixel backlit monochrome display presents caller information, directories, services, and soft-key prompts in the 7800 Series interface. Four programmable line keys handle lines, shared appearances, speed dials, or call features, with tri-color LED status for multi-call handling. 10/100/1000BASE-T Ethernet runs through two RJ-45 ports, one for the LAN connection and one for a downstream PC, using Category 5, 5e, or 6 cabling for 1000 Mbps links. IEEE 802.3af Class 1 PoE keeps switch-port power demand low at up to 3.84 watts. CP-7841-K9 also includes a wideband RJ-9 headset path, electronic hookswitch support through the auxiliary port, fixed messaging and directory keys, automatic gain control, acoustic echo cancellation, silence suppression, dynamic noise reduction, TLS and SRTP security, 802.1X authentication, and DHCP or static IP addressing.
CP-7841-K9 deploys on office desks, shared work areas, reception overflow positions, and operations seats where a user needs several call appearances on a managed voice platform. The phone registers through Cisco Unified Communications Manager 12.5 or later, Cisco Hosted Collaboration Solution using supported UCM versions, Cisco SRST, Webex Calling, or supported third-party hosted call control; dial tone comes from that configured platform, not from the handset alone. The two-position foot stand supports desk viewing angles, and the optional Cisco 7800 Series wall-mount kit supports wall placement when desks are removed or space is controlled. ORM Systems supplies this phone new and certified refurbished, with refurbished units factory reset and checked for keypad, display, audio, Ethernet, and PoE behavior before dispatch.

CP-7841-K9 price is $151.23, a 65% saving from the Cisco list price of $432.10. CP-7841-K9 is in stock and available for next-day dispatch. (terms applied)

CP-7841-K9 Use Case
User Access Voice Endpoint
CP-7841-K9 sits at the user access edge and terminates the desk voice connection on a Cisco 7800 Series four-line IP phone. The endpoint receives IEEE 802.3af PoE Class 1 power from the access switch, registers to the call-control platform, and presents four programmable line keys for assigned extensions, shared appearances, or speed dials. The integrated 10/100/1000 Ethernet switch preserves Gigabit workstation connectivity through the phone. The result is a standardized voice endpoint position with PoE-powered calling and desktop data pass-through on one access drop.
Campus Voice VLAN Edge
The phone operates on the campus access layer where voice VLANs, QoS markings, DHCP options, and call-control registration define endpoint behavior. Network teams place Cisco 7841 phones on PoE switch ports, assign device profiles in Cisco Unified Communications Manager or a supported hosted platform, and map the four line keys to user roles. CP-7841-K9 uses wideband handset, headset, and speakerphone audio while keeping desk cabling simple. The result is consistent voice endpoint policy across access closets without replacing Gigabit workstation paths.
Multi-Line Operations Desk
CP-7841-K9 fits desks that monitor several call appearances without requiring a sixteen-line endpoint. Operations teams configure the four programmable keys for primary extensions, shared lines, or speed dials, then use the 3.5 inch backlit grayscale display for caller context, directories, services, and soft-key prompts. The phone connects to the access switch through PoE and hands data onward through its 10/100/1000 Ethernet switch. The result is controlled multi-line call handling at standard desks while keeping endpoint hardware consistent across the Cisco 7800 estate.

CP-7841-K9 identifies the Cisco IP Phone 7841 hardware SKU. The 7841 model denotes the four-line member of the Cisco 7800 Series desktop phone family, while the CP prefix is Cisco's collaboration endpoint part prefix. The SKU is used for ordering the phone hardware rather than a license, power supply bundle, or firmware-only item.
What hardware type is CP-7841-K9?
CP-7841-K9 is an IP desk phone, not a switch, router, wireless access point, or analog handset. It connects to an IP telephony network through Ethernet, registers to a compatible call-control platform, and gives users physical call-control keys, speakerphone, headset connectivity, handset audio, and a local display for calling features and directories.
Where does Cisco 7841 sit in the Cisco 7800 Series lineup?
Cisco 7841 sits above the Cisco 7811 and 7821 in the 7800 Series by providing four programmable line keys and Gigabit Ethernet switching. It sits below the Cisco 7861, which targets users needing sixteen line keys. CP-7841-K9 fits teams that need more line visibility than a two-line phone without moving to a higher-button endpoint.
How many line keys does CP-7841-K9 provide?
CP-7841-K9 provides four programmable line keys. These keys support line appearances and feature access depending on the call-control configuration.
