Abstract: Described a conference call method and system that automatically and securely establishes a conference call without requiring participants to call in to a telephone company. The method and system include a security device to ensure that each of the parties called by the service provider is authorized to be one of the participants of the conference call. In particular, each participant is provided with a security identifier such as a personal identification number (PIN), password, voice identification (“PASSKEY”), or other identifier. The security identifier can be uniquely assigned to one participant or all of the participants can share the same identifier. To establish a conference call, a telephone service provider simultaneously calls each of the participants at the scheduled time of the conference call. Each participant provides the security identifier to the service provider and is connected into the conference call after authentication of the security identifier.
