To date, widespread is the connection to the Internet, which is a global public IP network with a large number of IP users and increased requirements for the capabilities of IP networks, using them not only for data transmission, but also for interactive video conferencing, transmission of voice information streams and for other real-time applications. Growth of network resources’ users entails the emergence of a large volume of transmitted information and the problem of reliable, secure data transmission, that is, to the problem of information security. The solution to this problem is the use of encryption algorithms, as well as the choice of the OS server, configuration and settings of the Asterisk software firewall. In this regard, this publication has developed a simulation model of a wireless telecommunications network based on PBX Asterisk software IP consisting of wireless devices -workstations, border wireless router, Asterisk server, IP cloud, Wireshark traffic analyzer and others. Using the NetDoctor utility of the Opnet environment, the security of the configuration of the built simulation model of the wireless telecommunications network based on the PBX Asterisk IP software was checked. To carry out simulation modeling of the developed network, settings of all network equipment are performed and experiments are carried out on it, as a result of which it is established that when using the G711, G729, G726 and G728 codecs, small delays are obtained in the interval Router 1 - IP Cloud - Router 2 when using the G711. The rest of the codecs have low latency values at other network sites. Also, a passive attack was performed on the network based on the Wireshark traffic analyzer to determine the protocols, connection time, IP addresses of the network to study the security of the wireless network. The obtained results are aimed at using them in the design of new networks or their modernization.
