ИССЛЕДОВАНИЕ СПОСОБА ПОСТРОЕНИЯ СЕТИ IP ДЛЯ ПЕРЕДАЧИ ТРАФИКА НА БАЗЕ АТС ASTERISK

The article is devoted to the study of the method of organizing an IP network for secure data transmission based on the IP-PBX Asterisk, used as a switching station and gateway for traditional PBXs. The purpose of the study is to analyze and model the parameters of the studied IP network using Opnet Modeller for model time when changing codec types during voice traffic transmission. The results of the study show how the value of the transmitted total load changes when the type of codecs changes, the other parameters change insignificantly.
