Abstract:

In recent times, the usage of Voice and Video over Internet Protocol (VoIP) services has increased tremendously. There are many signaling protocols such as Bearer Independent Call Control (BICC), H.323, Media Gateway Control Protocol (MGCP), Session Initiation protocol (SIP) etc., that are used for establishment of sessions and to carry out voice and video data services. SIP has become popular because of its easy implementation, flexibility and good scalability. Choice of Open Source SIP server software (OS-SIP Server Software) is important when deploying in a VoIP based network. So we need to

This diploma thesis focuses on attacks on PBX Asterisk, FreeSWITCH and Yate in LTS versions. In this work was carried out two types of attacks, including an attack DoS and the attack Teardown. These attacks were carried out using two different protocols, SIP and IAX. During the denial of service attack was monitored CPU usage and detected if its possible to establish call and whether if call can be processed. The Security of PBX was build on two levels. As a first level of security there was used linux based firewall netfilter. The second level of security was ensured with protocols TLS and SR

Abstract:

This Master’s thesis deals in detail with the SIP protocol – a method of communication between two entities, various types of transmitted messages and their content. Few SIP libraries are introduced and two of them are used for development of an application for audio/video conference-calls. Compilation of OPAL and PTlib libraries for Windows 7 Professional (64bit) is described, and problems resulting from lack of information provided by authors. New improved “how to build” is presented. At the end, paper focuses on several ways of development of mentioned application.

The improvement of SISP practices has rapidly become one of the most critical issues facing many organisations, including banks. Globally, the banking sectors, including the Saudi one, have developed and implemented many IS strategies. Several systems have been executed to support the countries’ economies which have benefited from the increased trading resulting from the greater flexibility in time and costs associated with banking transactions. To continue these achievements and to improve SISP processes, several factors require careful investigation based on their relationship to SISP succes

SIV env sequence variation arising from evasion of antibodies is well established and closely mimics the pattern observed in HIV-infected human patients, yet despite the exp

Abstract:

Strategic Information Systems Planning (SISP) is an important activity for helping Chief Information Executives (CIOs) and top management identify strategic applications and align Information Technology (IT) with business needs. Like all strategic planning, SISP requires measuring how well SISP is done and how planning is improving over time. The measurement of these intangibles is a complex exercise. There have been few efforts undertaken in the Information Systems (IS) literature to formally develop a model for assessing and measuring SISP efforts. In this study, two models were proposed:

The implementation of the SIP-based Voice over IP (VoIP) and multimedia over MANET is still a challenging issue as many routing factors affect the SIP signaling performance and the voice Quality of Service (QoS). The nodes' mobility in MANET cause dynamic changes on the route calculations, topology, hop numbers, and the connectivity status between the correspondent nodes. The SIP-based VoIP depends on the caller’s registration, call initiation, and call termination processes. Therefore, the SIP signaling performance has an important role for the overall QoS of SIP-based VoIP applications over

Abstract:

Sedulius sive Ilarleh. Bynames (cognomina) in the early medieval memorial tradition. – More than 2.000 personal names occurring in the libri vitae of Reichenau (D), St. Gall (CH) and Brescia (I) and also in the early documents of St. Gall are listed in this essay. These names are cognomina because of the significant appellative meaning in Old and Middle High German times. They are divided in 10 groups: (1.) ethnic bynames (type: Hesso, Latinus), (2.) bynames given at birth (type: Willicomo, Gotedanc) (3.) bynames designating relationship (type: Fater, Muatir), (4.) bynames from animals (type:

Abstract:

<p>Traditional public switched telephone networks (PSTN) are replaced more and more by VoIP services these days. Although it is good for saving costs, the disadvantage of this development is that VoIP networks are less secure than the traditional way of transmitting voice. Because VoIP networks are being deployed in open environments and rely on other network services, the VoIP service itself becomes vulnerable to potential attacks against its infrastructure or other services it relies on.</p><p>This thesis will present a discussion of security issues of the Session Initiation Protocol (SI

Abstract:

<p>Context awareness is an important aspect of pervasive and ubiquitous computing. By utilizing contextual information gathered from the environment, applications can adapt to the users specific situation. In this thesis, user context is used to automatically discover multimedia devices and services that can be used by a mobile Session Initiation Protocol (SIP) user agent. The location of the user is captured using various sensing technologies to allow users of our SIP user agent to interact with network attached projectors, speakers, and cameras in a home and office environment. In order to

Abstract:

The switched telephony network was designed for voice calls. Expansion of datacommunication has lead to a wide range of experimentation to create new services. Theses services take place outside the network. When adding new services we currently encounter problems due to limitations of the simple devices at end points. Theo Kanter has proposed a new model to remove these limitations; this model is called “Adaptive Personal Mobile Communication”. The model consists of several components in the application layer of ISO standard. This model is based on peer to peer connections and the purpose of

Abstract:

Session Initiation Protocol (SIP) is fast emerging as the next generation signaling protocol. It operates independently of the underlying network transport protocol, establishing sessions between multiple users irrespective if the media is voice, data or video. It is projected to eventually replace the existing multiple voice and video signaling protocols as a single protocol which achieves all. SIP implements a non-trivial grammar. Parsing this grammar to extract the protocol fields proves to be a high overhead for the CPU. This paper presents hardware offload architecture; the SIP Offload En
