Conference phones are meant for holding conferences between three and a bigger amount of participants. This allows all participants listening and speaking simultaneously. Usually the conference is begun by the participant having “Conference Phone”. Other participants call to a special number for a conference which connects them with “Conference Bridge” that joins all lines together.
