The use of telephone and VoIP (Voice over Internet Protocol) interviews has become necessary owing to the legal restrictions safety measures introduced during COVID-19 pandemic. This furthered scholarly dialogue surrounding choice interview mode, assumption that face-to-face are "gold standard" [Novick, 2008: 397]. general public also more accustomed utilising in their day-to-day lives. In this...

Voice over Internet Protocol (VoIP) and its underlying Session Initiation (SIP) are widely deployed technologies since they provide an efficient fast means of both voice data communication a single network. However, in spite their advantages, also have security threats due to the inherent vulnerabilities (IP) that can potentially be exploited by hackers. This study introduces novel defense mech...

Voice over Internet Protocol (VoIP), is a technology that allows you to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line. VoIP services have compelling technical advantages over circuit switching. VoIP networks are based more on an open architecture than that of their circuit-switched contemporaries. This open, standards-based architecture means...

Voice over IP (VoIP) systems are gaining in popularity as the technology for transmitting voice traffic over IP networks. As the popularity of VoIP systems increases, they are being subjected to different kinds of intrusions some of which are specific to such systems and some which follow a general pattern of IP attacks. VoIP systems pose several new challenges to Intrusion Detection System (ID...

How can we obtain realistic mobility models? This has been a question that many researchers have attempted to answer, mostly by analyzing existing WLAN traces. But in the future, will user on-line behavior change with the introduction of new mobile services and devices? We aim to investigate this issue in our study. In this paper, we analyze the mobility of a subset of users different than the ...

The growing importance of VoIP telephony over untrusted networks raises the requirements to encrypt VoIP calls. To achieve a good trade-off between audio quality and network traffic, Variable Bit Rate (VBR) codecs are widely employed. VBR codecs encode speech data at different bit rates depending on the complexity of the input signal. We implemented a practical side channel attack on VoIP appli...

The Long Term Evolution (LTE) is a high data rates and fully All-IP network. It is developed to support well to multimedia services such as Video, VoIP, Gaming, etc. So that, the real-time services such as VoIP, video, etc. need to be optimized. Nevertheless, the deployment of such live stream services having many challenges. Scheduling and allocating radio resource are very important in LTE ne...
