A system and method for identifying users dropped from a conference call and rejoining the user to the call upon reconnection. Users can participate in the conference by connecting through different types of networks using a device having one or more types of communication lines. When a user is disconnected before the end of the conference (due to a bad mobile phone connection, for example), a bookmark is placed in the recording indicating the disconnection point. When the user rejoins the conference, the user is given the option to begin listening to the conference at the point where the user was disconnected. The user can issue playback-type requests, such as play, rewind, fast forward, etc., to review missed information. Other users are alerted by a characteristic tone when a user disconnects from the conference and by another characteristic tone when the disconnected user rejoins the conference.
