CP-7861-K9 Description
CP-7861-K9 is a Cisco IP Phone 7861 desk phone in the Cisco IP Phone 7800 Series, designed for enterprise IP voice users who need a Cisco call-control endpoint with more direct line access than the lower-key 7800 models. It supports sixteen programmable line keys, a 3.5 in. 396 x 162 pixel grayscale display, an integrated 10/100 Ethernet switch for LAN and downstream-device connectivity, IEEE 802.3af Class 1 PoE with power consumption not exceeding 3.84 W, wideband audio with a full-duplex speakerphone, and Cisco Unified Communications Manager 12.5 and later support with the Enhanced User Connect License boundary.

Application Scenarios
Deploy CP-7861-K9 for administrative, manager, or operator positions that need many visible line appearances or feature keys without moving outside the Cisco IP Phone 7800 Series.
Fit this phone into access networks where the desk phone and optional downstream device can stay on 10/100BASE-T Ethernet while the user still needs the larger sixteen-key layout.
Place CP-7861-K9 on Cisco Unified Communications Manager bills of material where Enhanced User Connect License coverage is already planned for the desk endpoint.

- In a CP-7861-K9 vs CP-7841-K9 comparison, the main difference is sixteen line keys on CP-7861-K9 versus four on CP-7841-K9, while CP-7841-K9 is the 7800 Series model with 10/100/1000BASE-T Ethernet.
- The CP-7861-K9 vs CP-7821-K9 difference combines line-key count and CUCM license tier: CP-7861-K9 has sixteen line keys with Enhanced UCL, while CP-7821-K9 has two line keys with Basic UCL.
- For buyers deciding which model to choose, the CP-7861-K9 comparison should confirm whether the desk requires sixteen visible keys before accepting the 10/100BASE-T Ethernet path.
Selection Guide
1. Reserve the 7861 for sixteen-key user positions
Choose CP-7861-K9 when the user profile needs sixteen supported line keys. Select CP-7841-K9 for four-line desks and CP-7821-K9 for two-line desks.
2. Check the desktop Ethernet requirement separately
Keep CP-7861-K9 on orders where 10/100BASE-T is acceptable for the phone and downstream-device ports. Move to CP-7841-K9 only when the 7800 Series desk design requires Gigabit Ethernet pass-through.
3. Align the CUCM entitlement with the phone tier
Attach Enhanced User Connect License coverage for Cisco Unified Communications Manager. Do not substitute a Basic UCL plan that fits the 7811 or 7821 tier.
4. Treat color and mounting as separate order lines
Confirm whether the deployment standard is charcoal CP-7861-K9= or white CP-7861-W-K9=, then add the CP-7861-WMK= wall-mount kit only where the desk layout requires wall installation.

|
Cisco PID |
CP-7861-K9= for Cisco IP Phone 7861 |
Prevents substitution with a lower-line-count 7821 or 7841 phone |
|
Line-key requirement |
Sixteen supported line keys on Cisco IP Phone 7861 |
Confirms that the user position needs the 7861 layout instead of a smaller 7800 Series model |
|
Desktop Ethernet path |
10/100BASE-T LAN and downstream-device ports |
Flags requests that actually require the Gigabit Ethernet pass-through of CP-7841-K9 |
|
Voice platform baseline |
Cisco Unified Communications Manager 12.5+, Cisco Hosted Collaboration Solution 8.6.2+, or Cisco SRST 8.x+ |
Keeps the endpoint matched to Cisco-documented call-control support |
|
CUCM entitlement |
Enhanced User Connect License |
Avoids attaching Basic UCL coverage that belongs to the 7811 and 7821 tier |
|
Power method |
IEEE 802.3af Class 1 PoE or Cisco Power Adapter 3 |
Separates switch-powered desks from locations that need an external Cisco power adapter |
|
Color and mounting extras |
CP-7861-K9= for charcoal, CP-7861-W-K9= for white, and CP-7861-WMK= if wall mounting is required |
Keeps color and mounting decisions from being hidden inside the base phone SKU |

Even with holiday delays in the carrier network, shipment arrived on time.
Documentation included matches what we’d expect from a sealed retail unit. Invoice formatting was a bit different from what our AP system expects, but workable.
We ran a cost comparison across four vendors. Layer23 was the clear winner. Wish the lead time was a bit shorter, but product quality made up for it.
Looks complicated but it’s very helpful. Seller was very kind.
16 lines! I can see everyone’s status. Great phone for front desk.
