Which call control platforms does CP-8865-K9 register to?

CP-8865-K9 registers to Cisco Unified Communications Manager 8.6.2, 9.1.2, 10.5.2, 11.0 and later, and to 8.5.1 with nonsecure mode only. BE 6000 supports 8.6.2, 9.1.2, 10.5.2, 11.0 and later, and HCS supports 8.6.2 and later. Signaling is Session Initiation Protocol, and the CUCM license is Enhanced User Connect License.

What PoE class does CP-8865-K9 need?

CP-8865-K9 is an IEEE PoE Class 4 phone, compatible with IEEE 802.3af and 802.3at switch blades. With two or three key expansion modules it needs 802.3at PoE or a CP-PWR-CUBE-4 power cube with the country cord, and the rear USB fast charge is lost on 802.3at unless the port supplies UPOE.

Which key expansion module PIDs does Cisco list for CP-8865-K9?

The 8865 datasheet lists CP-8800-V-KEM= (Charcoal), not CP-8800-A-KEM=. The 8865NR datasheet lists CP-BEKEM= (Charcoal) and CP-BEKEM-W= (White) instead. Cisco does not state whether the PIDs are interchangeable, so confirm the module against the physical unit when ordering.

Which spare parts does Cisco list for the CP-8865-K9 video phone?

Video-phone bezels are CP-8800-B-VID-BEZEL= (black) and CP-8800-S-VID-BEZEL= (silver). The datasheet also lists the CP-8800-FS= foot stand, CP-DX-HS= handset and CP-DX-CORD= handset cord. Standard 8800 bezels do not fit the video models, which use their own VID bezel PIDs.

How much current can the rear USB port on CP-8865-K9 supply?

The rear USB port supplies 500 mA and can be raised to 2.1A at 5V, while the side port supplies 500 mA, per the 8865 datasheet. The phone supports UPOE, and 802.3at PoE is the baseline for accessory USB charging.

How many USB devices can one USB port on CP-8865-K9 serve on MPP firmware?

Up to five devices per USB port, and each key expansion module counts as one device, per the MPP technical details. Unpowered hubs are not supported, and neither are powered hubs with more than four ports.

Which Wi-Fi bands does CP-8865-K9 use?

The phone uses 802.11n at 2.4 and 5 GHz and 802.11ac at 5 GHz, per the MPP technical details. The same document lists the Bluetooth radio as version 4.1.

Can CP-8865-K9 register to Cisco Unified CME?

No. The IP Phone release notes mark CME as unsupported on this model. CME 10.0 with IOS load 15.3(3)M is the release they list for the models that do register. Firmware 14.3(1)SR3 covers CP-8865-K9, but 14.4(1)SR1 does not.

CP-8865-K9 Description

The CP-8865-K9 is a Cisco IP Phone 8865 video desk phone in the 8800 Series for Unified Communications desks that carry HD video calls. The phone has five programmable line and feature keys, a 5 in. 800 x 480 color display, 720p HD video, 802.11a/b/g/n/ac Wi-Fi and Bluetooth 4.1 for mobile integration. It takes up to three key expansion modules, and with two or three modules the rear USB fast charge is lost on 802.3at PoE unless the port supplies UPOE.

Application Scenarios

Executive Video Desk

On an executive or manager desk, the phone carries 720p HD video calls on its 5 in. color display, with Bluetooth 4.1 pairing a headset or a mobile phone.

Reception With Expansion Modules

At a front desk that covers many lines, up to three key expansion modules extend the five line keys to 113 line buttons.

Desk Shared With A PC

Where one access-switch drop serves the phone and a co-located PC, the internal 2-port Gigabit Ethernet switch passes the PC connection through the phone.

CP-8865-K9 and CP-8865NR-K9 differ in radios: CP-8865-K9 includes 802.11a/b/g/n/ac Wi-Fi and Bluetooth 4.1, while CP-8865NR-K9 has neither radio. Sites that bar wireless devices from the desk need CP-8865NR-K9, which also allows up to 10 line keys in Enhanced Line Mode against 5 on CP-8865-K9. CP-8865-W-K9 matches CP-8865-K9 in every table row except its white finish. All three video phones take up to three key expansion modules, and two or three modules need 802.3at PoE or a CP-PWR-CUBE-4 power cube.

Ordering Checklist

Power source: Use IEEE 802.3at or UPOE PoE, or CP-PWR-CUBE-4 with a country cord. A desk without PoE has no power, and the cube is not powered without its country cord.
Key expansion module: Order CP-8800-V-KEM= for each module, up to three per phone; with two or three modules use 802.3at or a power cube. The rear USB fast charge is lost on 802.3at with two or three modules unless the port is UPOE.
Wall mount: Order CP-8800-VIDEO-WMK= for the video phone; the 8865 has no wall kit for a phone with a module. Wall placement needs the video mount on the order, and a module cannot be wall mounted with it.
