Application Scenarios
Use CP-8841-K9 when the desk-phone standard calls for a Cisco 8800 Series endpoint with a color 5-inch WVGA display rather than the grayscale 8811 screen.
Fit this SKU into office desks where one access-switch drop must serve both the phone and a co-located PC through the Cisco-documented 10/100/1000BASE-T internal Ethernet switch.
Select CP-8841-K9 for Cisco Unified Communications Manager environments where Enhanced UCL is already planned and the site can provide PoE Class 2 or the correct Cisco Power Cube 4 country-cord path.

- In a CP-8841-K9 vs CP-8841-W-K9 comparison, the table difference is the documented color: CP-8841-K9 is the charcoal 8841 and CP-8841-W-K9 is the white 8841.
- The CP-8841-K9 vs CP-8811-K9 difference is display type. CP-8841-K9 keeps the 8841 color WVGA screen, while CP-8811-K9 is the charcoal 8811 with a grayscale screen.
- For buyers deciding which model to choose, the CP-8841-K9 comparison should first confirm color standard, then confirm whether the endpoint requirement is the 8841 color display or the 8811 grayscale profile.
Selection Guide
1. Choose CP-8841-K9 for the charcoal 8841 endpoint
Select CP-8841-K9 when the bill of materials calls for the Cisco IP Phone 8841 in charcoal with five programmable line keys and a color 5-inch display.
2. Use CP-8841-W-K9 only for the white 8841
Move to CP-8841-W-K9 when the same Cisco 8841 phone is required in white for a desk-standard or room-design match.
3. Use CP-8811-K9 when grayscale display is acceptable
Review CP-8811-K9 when the buyer wants the same 8800 Series desk-phone class but does not need the 8841 color display.
4. Confirm license and power before release
Verify Enhanced User Connect License coverage for CUCM and decide between PoE Class 2 switching and Cisco Power Cube 4 with the matching regional AC cord.
