Abstract

The invention relates to a method for managing a packet switched, centralized conference call between a plurality of terminals (13). In order to enable an enhancement of the user comfort, it is proposed that the method comprises at a conference call server (12) receiving data packets from all terminals (13). Based on these data packets, then at least one terminal (13) currently providing voice data is determined. In a next step, the data received in the data packets is mixed, and the mixed data is inserted into new data packets together with at least one identifier associated to one of the terminals (13) which were determined to provide voice data, such that the at least one identifier can be distinguished from any other information in the data packets. Finally, the new data packets are transmitted to terminals (13) participating in the conference call. The invention relates equally to a corresponding server and to a corresponding terminal.
