1. VoIP Tuning Services Packet
   The transfer of voice traffic over packet networks, and especially voice over IP, is rapidly gaining acceptance. Many industry analysts estimate that the overall VoIP market will become a multi-billion dollar business within three years. While many corporations have long been using voice over Frame Relay to save money by utilizing excess Frame Relay capacity, the dominance of IP has shifted most attention from VoFR to VoIP. Voice over packet transfer can significantly reduce the per-minute cost, resulting in reduced long-distance bills. In fact, many dial-around-calling schemes available today already rely on VoIP backbones to transfer voice, passing some of the cost savings to the customer. These high-speed backbones take advantage of the convergence of Internet and voice traffic to form a single managed network. 
                   
2. VoIP White Papers and Application Notes
   Listed here are Newport Networks' White Papers with brief summaries of the topics. There is an on-line version of each, plus a PDF copy of the papers may be downloaded from the document centre. VoIP Security is becoming ever more important as high profile fraud cases hit the press. Strong authentication of users helps mitigate these attacks, a fact recognised by 3GPP in the IMS security framework. But 'VoIP over IPsec' poses problems in wireline networks when it encounters NATs. This paper examines the problems when IPsec meets NAT and looks at TISPANs solution to the problem.
                
3. VoIP Papers and Presentations
   Voice over Internet Protocol (VoIP) is the technology used to transmit conversations digitally over the Internet. VoIP is being adopted globally and changing the landscape of telecommunications for businesses and consumers. This presentation describes VoIP and how it compares to traditional phone systems, the standards organizations promoting the technology, and what this means for you now and in the future. This paper describes what VoIP is, how it compares with the legacy phone technology, and what solutions can be devised using internet to carry voice. It also explores what government is doing to regulate this technology, how the standards organizations are organized, what businesses and other groups are trying to sell, and what this means for business and residential consumers.
              
4. VoIP Basics for IT Technicians
   The IP phone is coming - or has arrived - on a desk near you. The IP phone is not a PC, but it does have a number of hardware and software elements also resident in PCs. VoIP brings a new environment to the network technician that requires expanded knowledge and tools to deploy and troubleshoot IP phones. Previously, LAN diagnostic tools mainly had to analyze Ethernet, but now they must also support VoIP signaling protocols and voice transmission, so understanding VoIP will be crucial for the network technician. VoIP Basics whitepaper for insights into VoIP technology specifically for the network technician, including: - * Standards * Protocols * Hard and soft phone implementations * Gateways and call servers * LAN and WAN networks * Security
          
5. VoIP White Paper Meeting Center
   Genesys Conferencing is one of the world's first companies to offer a multimedia conferencing platform, which tightly integrates audio, web, multi-point video and enterprise solutions to provide the richest collaboration experience available in the marketplace today. With its commitment to innovation, Genesys is expanding its service offerings to include several variations of Voice over Internet Protocol (VoIP). VoIP is a technology that transmits voice over data networks. Its main application is to allow individuals to conduct voice conversations over an IP network instead of the existing Public Switched Telephone Network (PSTN). This paper will focus on VoIP solutions for enterprises.
               
6. VoIP Research Library
   Voice over Internet Protocol (VoIP) is a process of digitizing and sending voice telephone signals over the Internet or other data network. Enterprises of all sizes can benefit from this technology, but they must do some research to decide if VoIP is right for them. Which vendor should I call? Would I rather deploy and manage my telecommunications in-house, or does it make sense to outsource to a hosted services provider? How much will this cost, and how much money can I save in the long run? The first thing most people realize about VoIP technology is that it can save their business money by reducing or eliminating the toll charges for long-distance and even local calling. However VoIP is more than a plan to lower a company's phone bill. There are also so-called "soft" benefits enabled by VoIP, such as increased worker productivity, the ability to collaborate among multiple branch offices, and lower operational expenditures as a result of simplified management schemes.
