“…But, despite the many advantages of the Asterisk PBX, the problem of secure data transmission in the network, especially when it is scaled when the PBX acts as an independent service system, remains not fully understood [28][29][30][31][32]. Most research is currently focused on protocols and encryption [33][34][35][36], as well as the quality of the transmitted voice traffic [37][38][39][40]. This does not eliminate the main threats as the attackers are currently focused on something else [41].…”

The research problem described in this article is related to the security of an IP network that is set up between two cities using hosting. The network is used for transmitting telephone traffic between servers located in Germany and the Netherlands. The concern is that with the increasing adoption of IP telephony worldwide, the network might be vulnerable to hacking and unauthorized access, posing a threat to the privacy and security of the transmitted information. This article proposes a solution to address the security concerns of the IP network. After conducting an experiment and establishing a connection between the two servers using the WireShark sniffer, a dump of real traffic between the servers was obtained. Upon analysis, a vulnerability in the network was identified, which could potentially be exploited by malicious actors. To enhance the security of the network, this article suggests the implementation of the Transport Layer Security (TLS) protocol. TLS is a cryptographic protocol that provides secure communication over a computer network, ensuring data confidentiality and integrity during transmission. Integrating TLS into the network infrastructure, will protect the telephone traffic and prevent unauthorized access and eavesdropping.
