Research indicates that the utilization of existing symmetric and asymmetric cryptosystems, as well as steganography, fails to ensure the requisite security and reliability in IP networks, where IP PBX Asterisk assumes the role of information transmission facilitator through switching processes. Consequently, this publication undertakes the development and investigation of a four-tiered information protection method when employing various voice codecs in IP networks based on IP PBX Asterisk. The adoption of multi-tiered protection significantly prolongs the cryptanalysis duration for malicious actors, thereby serving as a deterrent to information interception. The primary achievement of this research lies in minimizing the latency incurred during information traversal across the four layers of protection to less than 150 milliseconds, a benchmark widely acknowledged as optimal for assessing voice traffic service quality during transmission. It is noteworthy that a delay parameter of 150 milliseconds in telecommunications networks is pivotal; failure to meet this criterion at the receiving end may result in signal distortion such as jitter, audio degradation, unintelligibility, and other impairments. The devised methodology can be employed in networks transmitting highly classified or business-sensitive information. We contend that the developed encryption enhancement methodology, which prolongs the cryptanalysis duration for malicious entities and the conducted analysis, represents a novel scientific contribution.
