A presence server determines a presentity's media status and availability for engaging in real-time communication sessions in a presence system by receiving, from the presentity, a maximum number of real-time interactions per real-time media types supported by the presentity, and collecting presence information identifying real-time communication sessions currently engaged in by the presentity. The presence server determines the media status for each of the real-time media types supported by the presentity based on the maximum number of interactions and the presence information, and determines available real-time media types from the determined media statuses.
