  3. 2. Analyzing VoIP connectivity and performance issues

    Kandidat-uppsats,

    Författare :Mehenni Sadaoui; [2019]
    Nyckelord :VoIP; connectivity and performance issues; call quality; packet traces.;

    Sammanfattning : The appearance of Voice over IP (VoIP) revolutionized the telecommunications word, this technology delivers voice communications over the internet protocol (IP) networks instead of the public switched telephone network (PSTN), calls can be made between two VoIP phones as well as between a VoIP phone and an analog phone connected to a VoIP adapter [1]. The use of this technology gives access to more communication options compared to the conventional telephony but the users face different problems, mostly connectivity and performance issues related to different factors such as latency and jitter [2], these factors affect directly the call quality and can result in choppy voice, echoes, or even in a call failure.
