Cisco IP Phone 8800 Key Expansion Module

A key expansion module allows you to add extra line appearances or programmable buttons to your phone.
The programmable buttons can be set up as phone line buttons, speed-dial buttons, or phone feature buttons.
Simplified dialing is not supported on the expansion modules.
The following table describes the number of Key Expansion Modules supported by each model in the Cisco
IP Phone 8800 Series.

• Key expansion module 1 is the closest unit to the phone.
