The Cisco IP Phone 8800 Key Expansion Module adds extra programmable buttons to the phone. The programmable buttons can be set up as phone speed-dial buttons, or phone feature buttons.

There are 3 expansion modules available:

Cisco IP Phone 8800 Key Expansion Module—Single LCD screen module, 18 line keys, 2 pages, two-column display only.
Cisco IP Phone 8851/8861 Key Expansion Module—Dual LCD screen module for audio phones, 14 line keys, 2 pages, one-column display only.
Cisco IP Phone 8865 Key Expansion Module—Dual LCD screen module for video phones, 14 line keys, 2 pages, one-column display only.

The Cisco IP Phone 8851/8861 Key Expansion Module and the Cisco IP Phone 8865 Key Expansion Module require Firmware Release 11.2(3) or later.

You can use more than one expansion module per phone. But each module must be the same type. You cannot mix Cisco IP Phone 8800 Key Expansion Module with a Cisco IP Phone 8851/8861 Key Expansion Module or with a Cisco IP Phone 8865 Key Expansion Module. You cannot mix audio expansion modules with video expansion modules. You also cannot use a video expansion module on an audio phone or an audio expansion module on a video phone.

The following table lists the phones and the number of key expansion modules that each model supports.

Key Expansion Module Power Information

If you use a key expansion module with your IP phone, then Power over Ethernet (PoE) is enough to power your expansion modules. But, your phone must have an IP address in order to charge the expansion module.

A power cube is needed for smartphone or tablet charging when your key expansion module is attached.

A key expansion module uses 48V DC, 5W per module. If you are charging a smartphone or a tablet, note the following:

Side USB: Up to 500mA/2.5W charging
Back USB: Fast charging, Supports up to 2.1A/10.5W charging

The fast-charging feature on the back USB does not work when more than one key expansion module is attached to a Cisco IP Phone 8861 using 802.3at PoE.
The fast-charging feature on the back USB doesn’t work when more than one key expansion module is attached to a Cisco IP Phone 8861, unless Cisco Universal PoE (UPoE) is used.
Cisco IP Phone 8851 with 2 key expansion modules works on 802.3at PoE only with v08 or later hardware. You can find the phone version information on the lower back of the phone as part of the TAN and PID label. Version information is also located on the individual phone packaging.
