“…The test result at 32kbps cannot be present due to 100% packet loss on the usage of a-law codec. Prajwala et al [15] also experience the same result, G.711 (a-law) gives more delay compared to other codec on 128kbps bandwidth test.…”

The usage of internet protocol for voice communication is widely used and more efficient rather than an analog signal. However, there is no security guaranteed on IP-based voice communication. The voice payload can be easily tapped or even manipulated. In the case of improving the security aspect, communication quality should be also considered. VoIP requires sufficient bandwidth to get proper communication quality. The ITU-T released a standard unit of communication quality, known as Mean Opinion Score (MOS) which is made from the subjective judgments of some individuals. However, MOS method takes time and is expensive. In this research, we measure VoIP communication which is secured by using VPN and build a tool for analyzing the voice packet between communication peers. The tool has capabilities to measure delay, jitter, and packet loss. Since VoIP has a QoS standard by ITU-T, the usage of VPN for security purpose needs to be considered. The sound quality might be decreased due to the addition of header for tunneling method, as well as the additional delay when the encryption processing is carried out. We used 3 types of codec: a-Law, GSM, and iLBC which will be passed on 4 types of bandwidth (256, 128, 64, 32 kbps) through the UDP-based VPN that use 3 types of encryption method (3-DES, Blowfish, AES).

Critical infrastructure, which includes facilities necessary for the normal functioning of society (e.g., power plants, transportation hubs, hospitals, etc.), requires reliable communication to ensure uninterrupted operation and coordination of actions in emergency situations. This paper presents a methodology for measuring and improving the quality of voice communication via VoWi-Fi and VoLTE technologies at critical infrastructure facilities. One of the key aspects of the methodology is the creation of a test environment that reflects the real working conditions at critical infrastructure facilities. This includes using devices that support VoWi-Fi and VoLTE technologies, setting up Wi-Fi networks and mobile Internet access, and selecting standard test scenarios to assess voice quality. An important part of the methodology is measuring various communication quality parameters, such as signal strength, delay, and packet loss. For this purpose, special measurement tools are used, including the Ping Monitor and G-NetWi-Fi apps on the Android platform. The obtained data allow us to objectively assess the effectiveness of VoWi-Fi and VoLTE technologies at critical infrastructure facilities, in particular, using the proposed MOS (Mean Opinion Score) metric. It has been established that one of the main disadvantages of the traditional approach to using VoWi-Fi and VoLTE is the lack of automatic switching between these technologies in the event of a deterioration in the quality of one of them, which can lead to unsatisfactory perception of the conversation by the user. The proposed methodology involves the use of a MOS metric monitoring system that continuously measures the quality of voice communication on both technologies and implements a mechanism for adaptive switching between VoLTE and VoWi-Fi. This allows for automatic switching to the optimal technology depending on current conditions and provides the best quality of service for the user. In general, the article provides important information for implementing and optimizing these technologies at critical infrastructure facilities to improve the reliability and efficiency of voice communications.

“…It examines ways for determining the quality of packet telephony data transfer. A packet model was created and validated to account for VoIP architecture that supports several audio codecs for voice compression [14]. In LTE networks, the integration of packet technologies, codecs and QoS support mechanisms ensures that voice messages are perceived at a level of at least 4 on the MOS scale [15].…”

4G mobile connectivity protocol, LTE (Long Term Evolution), is lower dormancy and higher data rates. LTE overseers may utilize the current circuit to control voice through the fallback procedure Networks exchanged as LTE is totally Internet Protocol (IP) advancement. Voice over IP administrations (VoIP) are needed to give the voice over IP associations, similar to the Internet, to prevent this. Voice Codec is one of the basic sections of VoIP that can be communicated on Internet and change simple signs into compacted computerized parcels. In any case, there are various sorts of codecs that lift voice streams dependent on transfer speed and application necessities. There is, still, no default codec reasonable to everybody. Some codecs have better effectiveness, with different conditions and therefore the transmission capacity is lower. Every one of these qualities will influence the Ultimate corporate assortment of codecs. In this paper, investigation on various kinds of codecs is held that can be utilized with ns-3 test system in VoIP over LTE. Moreover, we have proposed some framework for examination of VoIP traffic over LTE nature of administration (QOS) by arranging various VoIP codecs. Furthermore, as far as deferral, jitter, parcel misfortune and error-proposed scenarios, the study of the different VoIP codecs across the LTE network has been evaluated.
