The Cisco Unified IP Color Key Expansion Module (KEM) attaches to your Cisco Unified IP Phone

speed dials, or programmable buttons to your phone.
You can add one Key Expansion Module (KEM) to the Cisco Unified IP Phone 8961 to add up to 36
extra lines or buttons, two Expansion Modules to the Cisco Unified Phone 9951 to add up to 72 extra

The programmable buttons can be set up as phone line buttons, speed-dial buttons, or phone feature
