High Quality Content by WIKIPEDIA articles! VoIP User is a community driven and financed SIP based VoIP network. The projects aim is to introduce people to the concept of VoIP by allowing members to experiment with SIP and IAX2 devices.The VoIP User network was designed to operate within a community environment and therefore differs substantially from most other VoIP networks. The main highlighted difference being that users can call PSTN phone numbers through VoIP User's PSTN gateway without incurring any call charges. The way that VoIP User is funded is noteworthy: Calls into VoIP User?s numbers generate a small amount of per minute revenue (the ?termination charge?), and this money goes into a community account or ?pot?.

Voice over IP Security
58,84 € *
ggf. zzgl. Versand

Voice over IP (VoIP) and Internet Multimedia Subsystem technologies (IMS) are rapidly being adopted by consumers, enterprises, governments and militaries. These technologies offer higher flexibility and more features than traditional telephony (PSTN) infrastructures, as well as the potential for lower cost through equipment consolidation and, for the consumer market, new business models. However, VoIP systems also represent a higher complexity in terms of architecture, protocols and implementation, with a corresponding increase in the potential for misuse.In this book, the authors examine the current state of affairs on VoIP security through a survey of 221 known/disclosed security vulnerabilities in bug-tracking databases. We complement this with a comprehensive survey of the state of the art in VoIP security research that covers 245 papers. Juxtaposing our findings, we identify current areas of risk and deficiencies in research focus. This book should serve as a starting point for understanding the threats and risks in a rapidly evolving set of technologies that are seeing increasing deployment and use. An additional goal is to gain a better understanding of the security landscape with respect to VoIP toward directing future research in this and other similar emerging technologies.

Voice over internet protocol (VoIP) over WiMAX
50,40 € *
ggf. zzgl. Versand

Existing wireless networks enable different important applications over IP based network such as public internet and Voice over Internet protocol is one of the important applications which have become a possible alternative to public switched telephone network (PSTN). This project investigates one of the time sensitive data applications on WiMAX i.e. VoIP. I carried on WiMAX because WiMAX networks provide advance features and protocols to support the Quality of service (QoS). This project also indicates about the impact of load and mobility on the voice calls. This book provides details about the Voice Over Internet Protocol (VoIP), Which includes types of VoIP calls, VoIP System and Components, VoIP Protocols, VoIP codecs and VoIP Quality of Service (QoS). It also provides detailed study of WiMAX including WiMAX Protocol Layer and WiMAX Quality Of Service(QoS)

IP Telephony Over IUG Network
50,40 € *

Traditional telephony last about 100 years in use as the basic voice communication because of its reliability that satisfy the normal needs. Packet switching network, especially the Internet, which rapidly spread , attract more and more applications, because of its flexibility and efficiency. One of the most important applications is VoIP, which transmit voice in the same method of transmitting data, taking into account that voice is a real time application. Once we can transmit the voice over IP network, we do not need to route calls using the expensive and large central switches of PSTN, since we can route the calls in the same manner that we route data in IP network. This is the task of the soft switch, soft switch may seem to be the counterpart of central office or PBX of PSTN network. Finally, this project outlines the overall system of VoIP communication, and then show how to implement a whole telephone system based on IP protocols. The implementation of this project will improve the telephony service and management in (IUG).

Der Umsatz des Electronic Commerce hat sich in den letzten Jahren vervielfacht. Im Mittelpunkt steht die Kundenorientierung. Mit diesem Ziel sind die Service- und Supportprozesse zukunftsorientiert zu entwickeln und die weiter bestehenden Vertriebswege anzupassen. Der Service und Support über mehrere parallele Kanäle kann über Teleweb geleistet werden. Teleweb ist ein technologie-gestützter Prozess, der die beiden Technologien Collaborative Browsing und Telefonie unter Nutzung der Kommunikationsdienste Internet und PSTN/VoIP über einen CTI-Server integriert, welcher von mindestens zwei Personen parallel benutzt wird. In dieser Arbeit werden dafür die Grundlagen erarbeitet und ein Prozessmodell entwickelt. Bei der Umsetzung ist der Focus auf Call Center gerichtet.
