There are a number of things that can provide "device state" in Asterisk.  That 
includes "real" devices such as SIP endpoints, or any other channel driver. 
However, it also includes things like monitoring the state of a space in 
parking, or the usage of a MeetMe conference.  I have also written a small 
dialplan function which lets you create custom device states.  A lot of people 
use this for things like having a light on the phone that reflects whether the 
agent is logged in or not.
