Stress Testing of Internet Telephony

The thesis deals with the development of a module for JMeter that adds SIP stress testing functionality that was previously missing in the program. The theoretical part of the thesis deals with Internet telephony and codecs used in telephony. The SIP protocol is discussed in detail and the end of this part is devoted to stress testing. The practical part focuses mainly on the development of the proposed module, where the code of the module is described in detail, but it also deals with the installation and configuration of the Asterisk PBX on which the proposed module is tested. The results of this testing are analyzed at the very end of this thesis
