Abstract: A network-initiated teleconferencing system and method. In one embodiment, teleconference setup information is received pursuant to a setup request for a teleconference generated by an organizer using a messaging module. A messaging server system associated with the messaging module is monitored to obtain retrieve teleconference state information. Relative to a scheduled time, notifications are sent to personal communication devices of one or more participants (external participants, internal participants, or a combination thereof), including the organizer, for receiving consent. Upon receiving one or more consent confirmations from the one or more participants indicative of accepting a call initiated by a network, a call handling process may be invoked to initiate calls to the one or more participants for establishing the teleconference at the scheduled time.
