Unattended meet-me-conference controlled by a telephone terminal

摘要

Creating the capability of a meet-me-conference call on a telephone terminal by actuation of a meet-me-conference button on the telephone terminal. The meet-me-conference button is actuated for a particular line appearance, and the meet-me-conference is then established by other telephone terminals calling the telephone number associated with that line appearance. The user of the telephone terminal can join the conference at a later point in time by going off-hook (call originator). As other parties call that line appearance, the telephone terminal adds them to the conference. As parties join the conference, their names are displayed on the telephone terminal, and a second button on the telephone terminal can be utilized to drop parties as they are added to the conference. A second actuation of the meet-me-conference button prevents further callers to the line appearance from being added to the conference which is also referred to as deactivation of the meet-me-conference.
