CONFERENCE-CALL SYSTEM AND CONFERENCE-SPECIFIC ACCESS CODES

摘要

A conference-call system receives a conference-specific access code from an invited participant of a conference call and a conference-specific access code from an initiator of the conference call. The conference-call system grants the invited participant access to the conference call when the conference-specific access code from the invited participant matches the conference-specific access code from the initiator. The conference-specific access code from the initiator and the invited participant each include a base code portion and a portion added to the base code portion by the initiator of the conference call.
