Last year the number of users who used basic voice call over IP networks considerably increased. Voice over IP (VoIP) network must provide intelligent services such as free phone (FP), account card calling (ACC) and others. It is needed to evaluate the influence of the new intelligent services on performance of SIP proxy server. Each intelligent service has own interaction between the intelligent network nodes and SIP proxy server. The analytical model of SIP proxy server which operates like soft SSP node was proposed in the paper. Development of analytical SIP proxy server model was based on Jackson's theorem. The calculation of the influence of services FP on SIP proxy server of the given network was carried out by using the proposed model
