The most important GoS parameter for networks with SIP protocol is end-to-end call setup delay. So far there were no coherent models allowing calculation of these parameters for networks with SIP protocol. Few models were developed but they are insufficient. In the paper we propose model which allows end-to-end call setup delay calculation for networks with SIP protocol. The model is using chain of M/G/1/K models and is applicable for network with any number of the links. There are two versions of calculation depending on service time distribution type. In basic form the model bases on deterministic service time distribution and equations for M/G/1/K were taken directly from the literature. In more sophisticated version, for uniform distribution of service time, equations were derived by the authors. The paper includes results of call setup delay calculation obtained using each distribution type. They show that there is no big difference when applying model with deterministic service time than using model with uniform distribution service time (for all checked scenarios the difference was below 3%). The results were verified by simulation.
