IETF (Internet Engineering Task Force) and other working groups have put lot of efforts to come up with a protocol, which could lay standards for Internet Telephony. These efforts gave birth to Session Initiation Protocol (SIP). The imminent acceptance of the SIP as an official IETF standard marks an important milestone to the IP telephony industry. That milestone is the merging of Internet based distributed technologies with traditional telephony. This paper describes what is SIP, its components, its various features and a basic overview of its working.

Voice over IP is contributing heavily to the productivity boon. VoIP makes location independence a reality, as specialists and support staff appear to be seemingly everywhere at once, providing a local touch and enabling human resource optimization. This white paper details the VoIP productivity phenomenon and cites examples of success.

As traditional TDM network evolve towards IP, both incumbents and new entrants are moving from traditional TDM switch telephony solution towards VoIP solution while companies and individuals want to reduce their rising communications costs. The consolidation of separate voice and data networks offers an opportunity for significant savings. Accordingly, the challenge of integrating voice and data networks is becoming a rising priority for many network managers. Companies are pursuing solutions which will enable them to take advantage of reduced costs of broadband networks for voice and data transmission, as well as utilize the Internet and company Intranets as alternatives to costlier mediums.

VoIP (Voice over IP) is a new technology that enables telephone communication over packet switched networks such as the Internet using the Internet Protocol (IP). Internet Service Providers (ISPs), Application Service Providers (ASPs), Local Exchange Carriers (LECs), and Inter Exchange Carriers (IXCs) may all desire or need to implement this technology in order to gain or retain a competitive edge by offering an array of new services to their subscriber base. In today's quickly changing computer services world, one thing is rapidly becoming clear. Computer and telephone technologies are merging. If the ISP, ASP, LEC, or CLEC does not integrate these two services and do it soon, their competitors may leave them behind. One way to maintain an edge in this market is to use a Linux-based solution. The hardware, software, and licensing benefits easily make Linux tempting.

Though VoIP is still evolving, packet-based telephony is becoming more advanced. Voice protocols have further developed to offer a richer set of features, scalability, and standardization than what was available only a few years ago. Today, Juniper Networks, Inc. has solutions that enable you to deploy reliable, high-performance networks that support VoIP services. Juniper Networks solution translates into lower maintenance costs by using a common, ubiquitous network to provide any number of services. The paper provides detailed information on the VoIP technology and the VoIP Network Solutions by Juniper.

In a relatively short period, Internet telephony has advanced rapidly. This appealing technology, which allows users to perform calls with a fraction of the cost of regular telephone calls by using IP networks to carry the voice signals, is growing ever more popular. Many developers and manufacturers now offer PC telephony hardware and software but also gateway servers are emerging to act as an interface between the Internet and the PSTN making VoIP calls almost an obvious choice. The white paper by Telco Systems introduces the concept of VoIP technology and goes on to explain the same in detail.

Voice over IP (VoIP) services have come a long way over the past several years. Plagued by initial concerns over substandard quality and questionable reliability, VoIP vendors have stepped up, and solved these early problems. Many VoIP providers now deliver toll quality transmission, and quality of service (QoS) levels have significantly improved to match the integrity provided by traditional voice systems.

This white paper presents a typical VoIP architecture and then suggests a framework for testing VoIP networks. The test strategy is presented as well as a detailed discussion of the actual testing required for each network element. A list of Voice over IP specifications is provided as an appendix as well as a list of acronyms. The main objective of this paper is to provide insight into the intricacies of designing Voice over IP networks of carrier grade quality. It is intended for network design and test engineers.

To transmit voice over any network, in particular IP network, one has to have an idea of what exactly are the issues in the transmission of voice over such media. The first, and the most preliminary, thing would be to discuss the concept of how the voice is channeled into a digital stream from an otherwise analog mode. This involves two complementing steps called Grabbing and reconstruction. There are a number of issues one has to keep in mind when designing a VoIP system. This paper aims to enlist and abstract some of them which are critical to a typical VoIP Design process.

This paper presents an overview of the main technical problems to be addressed for the provision of interoperable services between IP telephony and the PSTN. The pivotal element of the solution resides in an inter-working function (IWF). This function is typically implemented in a gateway whose requirements and behavior are here analyzed in terms of signaling and control protocols (control plane), user data transfer (user plane), and management features (management plane).

This white paper addresses Voice-enabled applications. Voice-enabled web services can be accessed from any phone at home, in the office and, via wireless, on the road. The calls are routed through the regular telephone network (Public Switched Telephone Network .PSTN), through any wireless phone network, or directly through the Internet using VoIP (Voice over Internet Protocol). Therefore, they feature ubiquity on top of simplicity.
