vicidial_live_agents list of statuses

Hi, what are the list of statuses captured in vicidial_live_agents table? I can see in the real-time report that a user is in Dead status, but when I query on the vicidial_live_agents table where status is Dead, I cant find any records which status is Dead. So, I was wondering if that table will really have a "Dead" status, or how do we capture users in "Dead" status on the vicidial tables?
