Wireshark is a software application that is used to capture packets in a network and present information about certain packets in as much detail as possible. Rather than using a traditional private branch exchange (PBX), we used a Raspberry pi, which is a set of credit card-sized single-board computers, as a server for handling voice and video call communications over a wired or wireless LAN network while monitoring the entire system. While some VoIP services require a computer or a dedicated VoIP phone, others allow you to make VoIP calls using your landline phone via a special adaptor. VOIP technology enables the transfer of multimedia data such as audio and video. Voice over Internet Protocol (VoIP) is one of the emerging technologies that may provide low-cost service with high-quality and availability. Many organizations choose to establish their own service in order to manage internal calls.
With the advancement of technology, the telephone network has become the primary mode of communication worldwide, and private businesses have increased their reliance on telephone communication. Dari hasil analisa, dapat disimpulkan bahwa jumlah data sebenarnya yang dikirim dan diterima hanya dapat dilihat dari bagian informasi detail paket. Dari data hasil pengukuran, Wireshark menambahkan beberapa byte sebagai informasi tambahan yang berisi informasi mengenai network adapter, IP, dan jenis protokol yang digunakan. Dalam publikasi ini, file hasil capture Wireshark yang didapatkan dari panggilan suara melalui sistem komunikasi Voice over Internet Protocol (VoIP) dianalisa. Keakuratan dalam interpretasi data memiliki peranan yang signifikan dalam analisa suatu hasil pengukuran.
From the analysis, it is concluded that the actual transmitted or received data can only be seen from the packet’s detail information section. From the data, Wireshark added some bytes as additional information containing network adapter, IP, and protocol information. In this paper, a Wireshark captured packet file obtained from a voice call made through Voice over Internet Protocol (VoIP ) system is analyzed. P> Accuracy in data interpretation plays an important part in experiment result analysis.
