• respectively transmitting an indication of the volume of the determined loudest audio and an identification of the node associated with the loudest audio from each of the one or more nodes of the respective one or more groups to a respective decision maker associated with each one or more groups;
• determining, in each one or more decision maker, the highest received volume and the associated identification;
• and
• instructing, by a decision maker, the node of the identification corresponding to the highest determined volume to transmit the received media stream of the endpoint associated with the determined loudest audio to one of:
• all nodes in the one or more groups and to a respective proxy associated with each of the one or more groups.
