If an organization is looking into IP telephony systems, they should make sure they have adequate power protection to achieve the same high availability they are accustomed to in their traditional phone system, a level of availability, which is usually higher than for other IT applications. This white paper addresses power protection issues for IP telephony systems and presents a number of considerations for ensuring high availability.

The IP telephony Cookbook is a reference document addressing technical issues for the set-up of IP telephony solutions. Its goal is to provide the user community with guidelines and information about the IP telephony world and everything related to it. Since the Cookbook is intended to be a technical document, the main target audience are the network engineers and system administrations at universities and (NRENs); however, university students and researchers may find it useful both for enriching their technology background as well as for finding information about advanced research topics and projects in the European community.

With the Internet explosion and advanced PC applications that use more and more bandwidth, the data network volume has increased dramatically and is now the dominant bandwidth consumer. Therefore, it now makes sense to use the data network to transport voice instead of the voice network to transport data traffic. This design guide covers the issues related to designing an IP telephony or voice over IP (VoIP) network for transporting voice and data over a common LAN or WAN infrastructure. Understanding the underlying technology used to transport voice traffic is important in designing an IP telephony network. Design principles used to deploy a successful LAN-based VoIP network will not necessarily work when applied to a WAN configuration. This document discusses the major hurdles that need to be addressed when designing either a LAN or WAN based VoIP network.

Enterprises in banking, insurance, real estate, and retailing have a basic business topology of dozens, hundreds, or thousands of small branch offices that are chartered to service their local communities. Communications-wise, these branches need both local telephony services to connect with customers and business applications such as e-mail, workflow, command and control, or technology support services to support hierarchical corporate infrastructures. IP telephony and an emerging suite of convergence applications can uniquely deliver outstanding reliability, productivity, and lower costs. These technologies and capabilities are at the heart of the business case to justify a new approach to the branch network.

The focus of this paper is customer premises equipment (CPE) devices. By subjecting a CPE device to the comprehensive battery of testing discussed, a robust solution can be demonstrated to a carrier whose customers have high expectations of reliability and quality of their communication systems. Many IP telephony systems have not met those expectations - they have been plagued by poor reliability, limited functionality, and disappointing sound quality. Carriers are looking beyond the hype attached to voice over Internet protocol and are measuring the performance of these products to the same standards as traditional systems. A testing regimen such as that described above provides assurance that the attributes of reliability and quality of service are available.

Due to regulatory conditions in today’s market, local toll bypass is the key driver behind IP telephony for service providers and customers alike. But IP telephony enables more than just the potential for cost reduction. The shift away from reliance on the public switched telephone network (PSTN) for voice services opens up new opportunities for enhanced service offerings. This paper examines four emerging services that could spearhead the widespread deployment of IP telephony services: unified messaging, Web-based call centers, Internet "call waiting," and voice virtual private networks (VPNs).

Vendors try to impress their customers with measures of reliability, but what does that mean? The Energizer Bunny keeps running when other batteries cannot. This demonstrates stamina, not reliability. This paper provides an in-depth view of all the issues relating to reliability and availability (the 99.999% goal) as they pertain to the PBX and network landscape.

Companies are migrating from dedicated, somewhat closed systems to open environments that converge diverse voice, data, and video applications onto single IP-based networks. In this new model, telephony runs as an application, and must operate on and interoperate with the IP network's data infra-structure and management environment. Success of an enterprise's telephony enabled business applications depends on their smooth integration into the IP network. This paper explores the new service requirements that this migration is creating for IP Telephony support services, the Avaya IP Support Services architecture and layered service options, and insights on how to select the right IP Support Service for the business.

At present IPv6 technology is primarily known for its almost unlimited IP addressing space. This capacity offers sufficient addressing space for countries, which currently lack IPv4 addresses. It can also be used to manage deployment of future mobile networks and their billions of terminals or to provide a permanent address for high speed, always on Internet access (xDSL, cable etc.) which is becoming standard. In addition to this capacity, IPv6 will be the catalyst for future communication evolutions within businesses, evolutions that will be characterized by a high level of mobility thanks to wireless technologies and massive introduction of peer to peer applications.
