Conventional wisdom holds that currently there are two types of network operators - those who are currently running VoIP and those who are thinking about it. Even those not planning on immediate implementation of Voice over IP would be reluctant to roll out infrastructure incapable of supporting VoIP. This solution note explores the attributes and characteristics of networks capable of properly supporting Voice over IP or other similar delay sensitive applications.

This paper talks about VoIP and IP Telephony. Legacy data rarely required transmission rates greater than 56 Kbps, it was easy to consider transporting it along with the already establish voice network. The other was created when IP traffic accounted for a greater volume than voice on carrier networks. This view was, and still is, "Build a data network, and the voice will ride for free." This is the view of convergence that is the basis of voice over IP (VoIP).

Instant Teamwork is a collaboration technology that lets any device, in any location, communicate and work with any other devices in various and potentially geographically diverse locations. This includes the platform of course - being able to share voice, data, and even video, but it also includes applications. Instant teamwork means integrating capabilities into major applications that allow for easy capture and summarization, integrated collaboration tools, and spontaneous collaboration, when needed, between devices. This paper will look now at the various components that are needed to enable VoIP on a client PC, as well as the various standards and specifications that play a major role in enabling VoIP on the PC.

When managing an enterprise VoIP environment or a multi-client infrastructure for delivering hosted services, there are several key requirements that must be addressed at each stage of its lifecycle. Viola Networks has defined a 4-stage lifecycle framework for managing the design and delivery of cost-effective business-class VoIP services. This framework can be used to evaluate and implement a VoIP lifecycle management system. A comprehensive VoIP management solution must address these requirements with tools that support best practices that create business value. Viola's lifecycle management framework covers the full spectrum of management requirements, from planning through production, when building a large-scale VoIP services operation.

This white paper describes VoIP Lifecycle Testing. As the technology has matured and new business benefits have emerged, more companies are implementing voice over their corporate Internet Protocol (IP) networks. To ensure the success of VoIP implementation, project teams should therefore pay close attention to their network testing tools and practices. In particular, they should strongly consider implementing true “lifecycle” testing technology.

A VoIP solution that is truly easy to implement and manage can pay for itself very quickly, sometimes in a matter of months. However, manageability depends largely on the underlying architecture of the voice system. Some platforms are extensions of legacy voice switches, others are built on top of legacy data technologies, and still others were designed from the ground up for converged voice and data. This paper examines the impact these very different starting points have on management and it considers what should be possible when voice is managed via IP.

The business case for VoIP has a strong cost saving focus, based on lower call and line costs, but also in reduced administration and increased flexibility of the service. But there are other considerations for enterprises considering VoIP, such as the size and distribution of their offices. It is important for enterprises to focus on the wider picture, looking beyond the headline cost savings, in deciding whether or not to migrate to VoIP. This White Paper is designed to be a management guide to VoIP, and is based primarily on the results of a large-scale survey of end-user enterprises in the UK across a range of business sectors and sizes.

The purpose of this paper is to examine, from a numbering perspective only, the impact of Voice over Internet Protocol (VoIP). This paper provides background information on VoIP service but the primary focus is intended to examine how the service uses telephone numbers from the PSTN and how this use potentially affects the life and present assignment and administration of NANP numbers.

Today’s VoIP solutions fall into three basic categories, systems evolved from traditional PBX platforms, systems evolved from traditional data-switch platforms, and systems designed from the ground up for VoIP. All three of these architectures can be used to deliver VoIP systems with reliability, but they involve different degrees of complexity and cost. This paper examines the effects that these different architectures have upon the ability to deliver IP-based voice systems that are both highly available and cost effective.

The growth in popularity of electronic commerce on the Internet, such as advertising on the Web, providing product information, ordering, and order taking, means that enterprise communication systems must be able to support to highly network-oriented businesses. The voice over Internet protocol (VoIP) is an attractive approach to meeting these requirements. This paper gives an overview of integrating voice and data by using VoIP technology and describes Hitachi's solutions for IP-based enterprise communication systems for both wide area networks (WANs) and local area networks (LANs).
