Voice broadcasting, also known as Auto Dialing or Robo Dialing, is a mass communication technique, begun in the 1990s, that broadcasts telephone messages to hundreds or thousands of call recipients at once. Voice Broadcast users can contact targets, whether they be members, subscribers, constituents, employees or customers, almost immediately. When used by government authorities, it may be known as “reverse 911,” since such notifications are intended only for use in emergencies.
Voice broadcast systems manage a database of phone lists, as well as digitally recorded phone messages. Using telephony components, these computers can simultaneously broadcast thousands of phone messages.
Advanced systems include telephony boards with answering machine detection, and the logic to properly play a unique message to answering machines without message truncation.
