From state of the art technologies for load balancing and reliability increase in VoIP infrastructures one learns that no homogenous solution exists. Thus compromises have been made as in the number of machines versus achieved reliability, or with regard to separation of load balancing and failure resilience. In this paper we present a distributed architecture for VoIP services based on peer-to-peer principles. In contrast to other peer-to-peer based approaches, relying upon an external DHT service, our architecture utilizes peer-to-peer technologies to integrate load balancing and failover requirements with a centralized VoIP server concept. This results in an integrated solution with focus on todays service provider requirements. Within the scope of this work, a proof-of-concept software solution has been designed and implemented. We show that the proposed architecture can be easily scaled up and provides efficient, redundant storage for user and session data.
