Cisco CP-8800-A-KEM-3PC - 28-Key Audio Expansion Module for 8851 and 8861 MPP IP Phones - New

The Cisco CP-8800-A-KEM-3PC is the Audio Key Expansion Module with Multiplatform (MPP) Firmware designed exclusively for the Cisco IP Phone 8851 and 8861 running MPP host firmware — not for the 8865 video phone, and not for 8800 Series phones running Cisco Enterprise (UCM) firmware. It adds 14 physical buttons across 2 pages for 28 total programmable line, speed dial, and feature keys, illuminated by multicolored LEDs and labeled on dual color LCD displays. Ideal for receptionists, administrative assistants, executives, and busy office users on third-party SIP, UCaaS, and Webex Calling platforms running supported MPP firmware (version 11.2.3 or later). The module draws power from the attached phone through the spine connector; depending on how many KEMs are attached, the host phone itself may need 802.3at PoE or the Cisco Power Cube 4.

Cisco CP-8800-A-KEM-3PC - Key Features & Benefits

• 28 Programmable Buttons: 14 physical multicolored LED buttons across 2 pages deliver 28 total programmable keys for directory numbers, speed dials, BLF/line status monitoring, and feature keys — ideal for high-volume call coverage
• Dual Color LCD Displays: Two graphical TFT color LCDs with 16-bit color depth and backlight clearly label each programmable key for instant identification of line status (idle, ringing, busy, or null)
• MPP Firmware — Requires an MPP Host Phone: Built for Cisco Multiplatform Phone firmware (MPP) supporting third-party call control (SIP) on open SIP, UCaaS, hosted PBX, and Webex Calling platforms; requires MPP firmware version 11.2.3 or later on the host 8851 or 8861. Not intended for on-premises Cisco Unified Communications Manager (UCM) deployments running Enterprise firmware
• Scalable Expansion — Up to 3 KEMs per Phone: Attach up to 2 KEMs to the 8851 or up to 3 KEMs to the 8861 for a maximum of up to 84 additional programmable keys across three side-by-side modules on a single 8861 (28 keys per module x 3 modules)
• Plug-and-Play Side-by-Side Installation: Connects to the phone’s accessory port via the included spine connector with a matching foot stand; powered directly from the host phone at 48V DC, 5W per module — no separate power adapter needed for the KEM itself

Cisco CP-8800-A-KEM-3PC - Frequently Asked Questions (FAQ)

• Will this work with my Cisco Unified Communications Manager (UCM/CallManager) deployment?
  The CP-8800-A-KEM-3PC is the Multiplatform (MPP) version and is designed for MPP host phones running third-party SIP, UCaaS, hosted PBX, or Webex Calling deployments. It is not intended for on-premises Cisco UCM environments running Enterprise firmware. If your 8851 or 8861 runs Enterprise (UCM) firmware, you need the non-MPP variant (CP-8800-A-KEM=) instead.
• Is this compatible with the Cisco IP Phone 8865?
  No. The Audio KEM (CP-8800-A-KEM-3PC) is supported on the 8851 and 8861 only. The 8865 video phone requires the Video KEM (CP-8800-V-KEM-3PC) — audio and video KEMs cannot be mixed on the same phone.
• How is the KEM powered, and do I need anything extra?
  The KEM itself does not have its own power port — it draws power from the attached phone via the spine connector at 48V DC, 5W per module. The host phone’s power source is what scales with the number of KEMs attached: Cisco generally recommends 802.3at PoE (or the Cisco Power Cube 4) when any KEM is attached. Configurations with two KEMs on an 8851 typically require the Cisco Power Cube 4. Confirm the exact power requirements for your phone hardware version and KEM count against the Cisco IP Phone 8800 KEM data sheet power compatibility table.
