In this paper, the authors introduce their new VoIP model the aim of which is to meet the challenges of modern telephony. They present project concepts, details of implementation and their testing environment which was designed for testing many aspects of VoIP based systems. Their system combines mechanisms for ensuring best possible connection quality (QoS), load balance of servers in infrastructure, providing security mechanisms and giving control over the packet routing decisions. The system is based on Peer-To-Peer (P2P) model and data between users are routed over an overlay network, consisting of all participating peers as network nodes.
