In this paper we evaluate the performance and behavior of P2P VoIP applications (Skype, Google Talk) under different network conditions. We adopt different values for capacities of critical links, delay and packet loss and assume the quality of received audio as the interest measurement for evaluating its performance. We use the PESQ algorithm to compare the sent and received audio in order to infer MOS and measure the impact of each network parameter over the quality of received audio. Instead of ranking VoIP P2P applications, this work aims at analyzing various performance aspects and pointing out the observed weaknesses and strengths.
