Method for carrying out a voice conference and voice conference system

A method of carrying out a voice conference with at least three voice terminals in a communication system, the voice terminals each having a receive channel to receive coded voice data occurring during the voice conference for the outputting of voice signals formed by decoding the received voice data at the respective voice terminal, and a recording channel to supply coded voice data for the voice conference, with the voice data to be supplied being formed by coding from voice signals recorded at the respective voice terminal, comprising:

• assigning at least temporarily one of the voice terminals to a first group such that the voice data supplied by way of its respective recording channels is decoded respectively for it into individual voice signals, these individual voice signals are superimposed to form an aggregate voice signal and the aggregate voice signal is coded into first aggregate voice data;
• assigning at least temporarily two of the voice terminals to a second group such that the second group only includes voice terminals for which extensive inactivity is identified at their respective recording channels;
• and
• supplying the first aggregate voice data to the voice terminals assigned to the second group by way of their respective receive channels for respective outputting of the first aggregate voice data.
