In this paper, we presented an analysis of VoIP traffic on both call and burst levels. The analysed traces were based on a real connection statistics and ON/OFF characteristics of VoIP coders equipped with voice activity detector (VAD). We stated that an exponential distribution is not valid for an approximation of connection duration times as well as for an approximation of the ON/OFF characteristics of voice coders regardless of their type. We also generated synthetic multiplexed VoIP trace and we computed its second order statistics - autocorrelation and Hurst parameter which showed that the trace reveals long-range dependence and self-similarity.
