Although Grade of Service is very important in VoIP providers evaluation, We wasn't able to find any paper regarding the topic of measuring GoS variables for IP networks utilizing SIP, which are defined like for PSTN/ISDN/GSM networks (post-selection delay, answering delay, release delay, or probability of end-to-end blocking). Due to the lack of research in this field, it was necessary to start from defining measures and cover the full path towards developing an testing application. The most demanding stage was to provide methodology for determining the GoS values in IP networks with SIP. During that phase it was significant to take characteristics of the SIP protocol under deep consideration. As a result of the research practical implementation of tester application was created and tested in operator environments.
