Feature and Benefits

The Cisco IP Phone 8800 Key Expansion Module’s large LCD display allows for quick and easy identification of associated buttons. You can adjust the brightness of the individual KEM LCD in the IP Phone 8851, 8861, and 8865 models using the settings menu.
The primary function of the 8800 KEM is to add additional keys to the IP Phone 8851, 8861, and 8865 models for directory numbers, speed dial, or programmable feature keys. These keys are illuminated, and when used as directory numbers or shared-line keys, they make determining line status simple. The 8800 KEM is an excellent call-coverage device. It offers features that are similar but are not meant to be directly comparable to those of traditional direct station selection/busy lamp field (DSS/BLF) modules; therefore, it is neither an operator nor an attendant console.
