A multi-endpoint (EP) conferencing system, including a decentralized scalable network of endpoints, includes a source EP configured to connect to a non-virtual target EP. The source EP being configured to transmit to the non-virtual target EP a conference list for distributing to non-virtual EPs and virtual EPs associated with the target EP. The source EP is further configured to receive a conference list of the non-virtual target EP, integrate the received conference list with its conference list to obtain an integrated conference list and distribute the integrated conference list, or parts thereof, to the virtual EPs and the non-virtual EPs. The source EP being further configured to receive a positive selection notification indicative of a requesting EP from EPs that would like to get data from the source EP. In response to receipt of the positive selection notification, the source EP is configured to transmit data to the requesting EP.
