Abstract: A teleconferencing system based on application software run on a primary server that establishes a teleconference involving a plurality of callers and at least one facilitator. The teleconferencing system enables transferring callers from the primary server to connected secondary servers, each of which is connected to the primary server, thereby enabling the size of the teleconference to scale either upon initiation of or during the teleconference. Callers may be transferred to secondary servers, and secondary servers may be added or removed from the teleconferencing system during a teleconference. The inventive teleconferencing system enables an almost unlimited number of callers to participate in a teleconference.

Abstract: A teleconferencing system for establishing a facilitator-led teleconference involving a plurality of callers, a facilitator, and at least one party that can receive transfers. The teleconferencing system is operated by the facilitator under the control of application software through a user interface. A facilitator-led teleconference is formed and the callers are informed of how to initiate a transfer to the party, such as by touching of a key on their telephone keypad. The system detects the callers who initiate transfer. If the party is available the initiating caller is automatically transferred to that party. If the party is not available, such as would happen if numerous callers initiate transfer to that party, the initiating callers are placed into a transfer queue. When the party becomes available the callers in the queue are then transferred in queue order.

Abstract: A teleconferencing system that enables facilitator-led teleconferences in which a caller can transfer their call to a different conference group, facilitator, or another party by initiating a transfer command, such as by pushing a particular key on their telephone keypad. Application software controls a switch that automatically transfers a caller to a different conference group, facilitator, or party when a transfer-initiating act, such as pressing a key on a keypad, is sensed. The transfer is reported to the current facilitator and to the new facilitator, if any, who is provided with contact information regarding the transferring-in caller.
