Abstract The use of Voice over Internet Protocol (VoIP) innovation is rising due to its various merits. Nevertheless, the ineffective bandwidth a key dilemma that restricts fast-rising VoIP innovation. main factor behind this sizable packet preamble. This research creates technique address created known as payload elimination (PldE). fundamental concept PldE exploit information (elements) pream...

The traditional circuit-switched telecommunication network and the packet-switched data network are converging to a single packet-switched network. One important application of the converged network is telephony communications, also referred to as VoIP (Voice over IP). Call signaling protocols, such as H.323, SIP and MGCP, have been developed to support VoIP communications. To enable devices us...

Skype, Google Talk, Yahoo voice etc. are all applications that enable the use of the Internet for voice conversations. They offer cost effectiveness and are easy to use, and due to these reasons many new VoIP applications are coming into existence. However, all forms of communications need to be monitored for security purposes to ensure their correct usage. With the development of more and more...

In recent years Voice over Internet Protocol (VoIP) has become a popular multimedia application over the Internet. At the same time critical security issues in VoIP have started to emerge. The Session Initiation Protocol (SIP) is a predominant signalling protocol for VoIP. It is used to establish, maintain and terminate VoIP calls, playing a crucial role in VoIP. This paper is aimed at developi...

Recently, Voice over IP (VoIP) has become an important service for the future internet. However, for ubiquitous wireless VoIP services, greater coverage will be necessary as promised by the advent of e.g. 802.11 WLAN based wireless meshed networks. Unfortunately, the transmission of small (voice) packets imposes high overhead which leads to low capacity for VoIP over 802.11 based multihop meshe...

Voice over IP (VoIP) is a technology to transport media over IP networks such as the Internet. VoIP has the capability of connecting people over packet switched networks instead of traditional circuit switched networks. Recently, the InterAsterisk Exchange Protocol (IAX) has emerged as a new VoIP which is gaining popularity among VoIP products. IAX is known for its simplicity, NAT-friendliness,...

Voice over Internet Protocol (VoIP) products is an emerging technology that can contain forensically important information for a criminal activity. Without having the user name and passwords, this forensically important information can still be gathered by the investigators. Although there are a few VoIP forensic investigative applications available in the literature, most of them are particula...

Voice-over-Internet protocol (VoIP) is an emerging technology that is beginning to replace traditional telephone services because it is much more cost effective for the consumer and businesses. Long distance charges are relatively a thing of the past, and in general there are more feature-rich services available over a VoIP line than traditional phone services. VoIP provides phone services with...

Voice over Internet Protocol (VoIP) is a service from the internet services that allows users to communicate with each other. Quality of Service (QoS) is very sensitive to delay so that VOIP needs it. The objective of this research is study the effect of different queuing algorithms within the router on VoIP QoS. In this work, simulation tool “OPNET Modeler version 14.0” is used to implement th...

Title of Thesis : AN ALGORITHM TO EVALUATE THE ECHO SIGNAL AND THE VOICE QUALITY IN VOIP NETWORKS Andre Neumann Kauffman, M.S., 2006 Directed By: Associate Professor, Steven A. Tretter, Department of Electrical and Computer Engineering Voice over the Internet Protocol (VoIP) has been increasingly popular, but reliability and voice quality remain important factors that limit the widespread adopt...
