The invention relates to a conferencing unit for multi-point communication in the course of a telephone conference. Previously, it was not possible to call up and document agreements and decisions in voice-based telephone conferences in a computer-aided manner. The reason was that in traditional conferencing units, all audio channels were mixed into an overall channel and therefore an undisturbed interaction of individual participants with the system is not possible. The invention enables an individual association of a conference participant with a decision processing unit, in which decisions can be announced in a dialog system and stored in a computer-readable format.
