This station is basically the same as the 1120 phone, but with simpler and less expensive body, simplified button locations, four discrete direction arrows for navigation, and a number of other simplifications.
The following are the common features between the 1220 and 1120 phones:
Four programmable feature keys.
The station also allows the user to customize feature key labels, with limitations.

However, the 1220 phone has the following changes:
The navigation function with its up, down, left, and right buttons replaces the navigation rocker.
The Enter button is at the center of the navigation buttons and not at the center of the rocker.
Integrated 10/100 Mbps Ethernet Switch. Only one network port is required for phone and PC.
The Conference key which is a soft key on the 1120 phone is a fixed key on the 1220 phone.
The 1220 phone supports attaching an expansion module to add up to 24 additional buttons (one module with Shift).
