This paper presents a comprehensive analysis of modern approaches to optimizing the transmission of voice information in computer networks and protecting it against potential cyber threats. The key factors affecting the quality of voice communication are examined, including packet delay, jitter, data loss, and route instability in multiservice networks. Particular attention is given to the functioning of VoIP technologies, routing mechanisms, and Quality of Service (QoS) tools that enable traffic prioritization and increase the stability of voice packet delivery. The study compares the efficiency of static and dynamic allocation of network node resources and analyzes the operation of a physical router versus a system with static resource virtualization. Using a simulation model, the behavior of voice, video, and data traffic is examined under various load scenarios. The obtained results show that applying virtualization ensures more uniform resource utilization, reduces delays, and prevents buffer overload compared to traditional approaches. At the same time, the limitations of static virtualization under variable traffic intensity are highlighted. The conducted analysis confirms the feasibility of applying router resource virtualization to improve the quality and reliability of voice data transmission in multiservice networks. The results may be useful for network technology specialists, VoIP solution developers, and researchers in the field of cybersecurity.
