Abstract: A conference participant attempting to log into a conference that has been rescheduled is informed that the conference has been rescheduled to such-and-such date and/or time. If the login attempt is before or during the conference, the participant is offered information pertaining to the conference. If the login attempt is after the conference has ended, the participant is offered the information plus a recording of the conference. An identifier is associated with the conference and used by the host and the participants to uniquely identify the conference.

Abstract: When one party to an active call has momentarily stepped away from the call that has not been put on hold, the other party can record and leave a message for the party that stepped away, and then hang up. The call is monitored for return of the party that stepped away. When the returned party begins to speak, the message is immediately played to the returned party in response. In a conference, after a conferee who wishes to leave the conference, records a message and hangs up, the conference is monitored for either a break in the conversation or conversation directed to the party that left, and in response the message is played to the other conferees.

Abstract: A conference manager establishes and controls a conference and subconferences for a plurality of telecommunication terminals so as to reduce telecommunication costs by establishing the conference and dynamically placing telecommunication terminals geographically located with conference or isolated remote telecommunication terminals geographically located remote from the conference into the conference. The conference manager requests that other conference managers establish subconferences to conference together remote telecommunication terminals that are geographically located together. The conference manager requests that the other conference managers extend these subconferences to the conference. Further, the conference manager controls the other conference managers to interconnect the subconferences if the conference manager determines that communicating cost can be lowered by interconnecting two or more of the subconferences.
