Architecture that presents general presence information and in-meeting presence information as advanced state presence information in the roster of a virtual conference meeting or session. For example, one advanced state is showing a user that was invited to the session but that has not joined into the session. The advanced state presence information can also then show what the user is currently doing (e.g., offline, busy, etc.). Moreover, the advanced state presence information can show the communications state (e.g., audio) of the user such as free/busy information, call information, desktop locked (to attend to other activities), and so on.
