“…Hence, some cost is incurred only in the case where the student is either beyond the campus WIFI range or is communicating with a person not on the WIFI. The study therefore confirms earlier works on the economics of IP-PBX which makes Voice over IP (VOIP) a cost-effective alternative to the legacy PBX or key system [27].…”

This paper reechoes the need to use VOIP-based communication channels in order to reduce the heavy cost burden of communication in Sub Saharan Africa and other developing countries. We focus specifically on the context of the campus environment and implement IP PBX to cut down the cost of placing and receiving voice calls, instant messaging and voice mails with other colleagues connected to an Asterisk server on WIFI-enabled networks. We are motivated by the ease and cost-effectiveness of setting up WIFI-enabled IP network infrastructure which in recent times could be extended to allow inter-institutional linkage to allow collaboration and research.

“…Yu have studied by capturing every incoming and outgoing SIP packet from the tcpdump data. In addition to the REGISTER flooding attack, we also identified the INVITE flooding attack [10]. Our major findings are (1) a REGISTER flooding rate of 200 msg/sec has the potential to deplete CPU resource and causes a Denial of Service (DoS) attack, and (2) an INVITE flooding rate with only 110 msg/sec could cause a DoS attack because of process stack overflow.…”

IP Telephony, Internet Telephony, Digital Phone or often also called VoIP (Voice Over Internet Protocol) is a technology that allows long-distance voice conversations with the Internet. The increasing number of VoIP users and other IP-based multimedia streaming services naturally raises security issues. Many users are likely to lose their privacy in communication. To overcome this security problem a security system must be implemented. Implementing a security system will use VPN Gateway using SSL and TLS encryption on the VoIP server. The VPN Gateway method is used to build a private network so that only certain users can use the private network. The TLS method is used to secure a user signaling session to the server. From the test results obtained that the VoIP server that uses VPN Gateway and TLS on the server can overcome the attacks e.g., eavesdropping, attacking authentication, teardown session, and denial of service.

“…A more comprehensive set of results is gathered by Yu [19] in a study of over 8 million intrusion attempts into a company VoIP network, operating using an IP-PBX. Additionally, included in the paper is an evaluation of three methods (disconnection of IP-PBX from the internet, firewall protection, and application protection) and their effectiveness when implemented in the IP-PBX.…”

Voice over IP is quickly becoming the industry standard voice communication service. While using an IP-based method of communication has many advantages, it also comes with a new set of challenges; voice networks are now accessible to a multitude of internet-based attackers from anywhere in the world. One of the most prevalent threats to a VoIP network are Denial-of-Service attacks, which consume network bandwidth to congest or disable the communication service. This paper looks at the current state of research into the mitigation of these attacks against VoIP networks, to see if the mechanisms in place are enough. A new framework is proposed titled the “Call Me Maybe” framework, combining elements of latency monitoring with dynamic protocol switching to mitigate DoS attacks against VoIP systems. Research conducted around routing VoIP over TCP rather than UDP is integrated into the proposed design, along with a latency monitoring mechanism to detect when the service is under attack. Data gathered from a Cisco Packet Tracer simulation was used to evaluate the effectiveness of the solution. The gathered results have shown that there is a statistically significant improvement in the response times of voice traffic when using the “Call Me Maybe” framework in a network experiencing a DoS attack. The research and findings therefore aim to provide a contribution to the enhancement of the security of VoIP and future IP-based voice communication systems.
