Abstract: Methods and nodes for enabling a teleconference involving multiple peer nodes in a P2P network (502). A first peer node (500) appoints a subset of the peer nodes to act as Floor Control Peers, FCPs, (504) in a floor control overlay by handling floor requests from peer nodes to make input to a floor in the teleconference.
