In this paper, we propose a SIP-based clustered architecture based on failover and load balancing mechanisms that are used to ensure the high availability and scalability of such systems. We define also a distributed test architecture in order to verify the performance of the implemented system. Experimental results show the importance of failover and load balancing techniques to build highly available systems and the use of load testing as a validation technique to detect servers failure and call losses.}, }
