Converged networks have been evolving since their initial deployments, with simple Voice over IP transport services giving way to next-generation networks supporting intelligent multimedia communications. The focus of the enterprise has evolved as well, moving from simple cost savings towards embedding communications into business processes, improving worker productivity, and enhancing customer interactions. Yet even the most advanced enterprises have typically limited their IP Telephony deployments to their own intranets, and not across the public network. Multiple integration challenges have prevented the full realization of end-to-end IP telephony communications.However, solutions are emerging that will reduce these challenges, and at the same time deliver an additional wave of financial and operational benefits.

With the potential for significant reductions in travel expenses, as well as conducting more productive meetings leading to more efficient and effective decision making, video conferencing has always held out tremendous promise within the enterprise environment. A major development recently has occurred in the communications environment that is likely to break down the limitations that have suppressed the growth of video conferencing. The migration to converged IP networks and the spread of IP Telephony has provided a receptive platform infrastructure that can enable video to become a fully integrated element within the telephony environment. This platform, combined with the technological advancements in video and collaboration tools are ushering in a new era of video telephony.

The vision that Avaya has for converged voice and data communications is to create a network environment that supports maximum enterprise efficiency. Session Initiation Protocol (SIP) [18] is a key technology for this evolution towards a converged communication architecture. SIP as an enabler of converged communication applications has been able to gain industry-wide acceptance by placing control of the communication across distributed networked entities and by providing a means of integration at various levels in the protocol stack. Such integration is now possible in a multi-vendor environment with multiple applications across a wide range of industry sectors. Converged communications that is driven by ubiquitous IP network connectivity defines the next stage of evolution in enterprise communications.

SIP is an application layer, peer-to-peer communication protocol that facilitates openness, simplicity, flexibility, and reuse in an “All IP” Architecture. This paper offers a look at how Avaya views SIP in enterprise evolution. It also describes SIP technology, elaborates on the role of SIP in realizing converged communications, and describes details of the SIP protocol and associated technologies.

Organizations with multi-vendor, multi-application and widely distributed communications systems need a reliable way to integrate and optimize their network infrastructure. Session Initiation Protocol (SIP) supports converged communication applications by placing control of the communication across distributed networked entities and smoothly integrating the various system levels. This white paper is designed to help business leaders understand the impact of SIP-based converged communication in Voice over IP (VoIP), Unified Communication and Customer Relationship Management (CRM) solutions. This paper also offers CIOs guidelines for migration to an enterprise SIP network, and details some new Converged Communication Solutions.

Education involves making connections. This paper explains that to make these connections a few decades ago, a school, or college needed only people, buildings, and books. To make them now requires an additional asset: network device ports. 10/100 Mbps switched Ethernet ports connect users at the educational institution to another world of information and tools. The ports can allow students to take distance-learning courses, faculty to put courses online, researchers to relay fieldwork, and everyone to collaborate with colleagues across town or around the world.

IP Accounting is a very useful accounting feature in Cisco IOS, but it is not as well-known as other features, such as NetFlow. However, compared to NetFlow, IP Accounting offers some advantages that make it an interesting feature to investigate. For instance, easy results retrieval via a MIB and limited resource consumption. Furthermore, access-list accounting currently cannot be solved with the NetFlow implementation. In this sample chapter from Network Management: Accounting and Performance Strategies, study the various IP Accounting features in Cisco IOS, learn to distinguish between different IP Accounting functions and understand SNMP MIB details. The chapter also provides a command-line reference.

Industry trends suggest that the PC and telephone user experiences will converge over the next several years. This convergence raises important questions for the HCI community: how should the PC-phone user experience be designed, and how does PC-phone technology affect work practices? This paper focuses on the first question and provides some initial data on the second question.

This paper demonstrates how service providers can achieve capital and operational savings while implementing packet trunking and migrate from circuit to packet services in their networks by installing the Optical Interface Unit (OIU) in the Lucent Technologies 5ESS Switch. The paper includes an overview of the architectures enabled by this technology. The general OIU platform is described, together with a discussion of implementation benefits, including voice quality, unified OAM&P, and protection.

The ability to deliver the highest voice and video quality across a network or subscriber base, under dynamically changing network conditions, and given the heterogeneous mix of subscriber access devices (including CPU, codec, Internet connection type and capacity), is the key determinant of service quality. Eyeball Networks' patented Any-Bandwidth Technology guarantees every subscriber the best possible voice and video quality over any Internet connection and on any device - every time.

As IP technology advances, enterprise fax servers are advancing as well and are now beginning to support FoIP communications in much the same fashion as they support telephone-based systems. For organizations considering adopting or transitioning to an IP-infrastructure, the role of the fax server is stronger than ever. FoIP brings many benefits, and when deployed properly with a RightFax Server it can be the right transport mechanism for an organization. This whitepaper discusses how fax servers and FoIP investments fit into an organization's overall document delivery strategy. It also calls attention to issues and challenges organizations should consider when determining how best to take advantage of traditional telephone-based systems, FoIP, or a mix of both, with their fax server.

While Internet telephony aims to provide services at least equal to traditional telephony, the architecture of Internet telephony is sufficiently different to make it necessary to revisit the issue of feature interaction in this context. While many basic feature interaction problems remain the same, Internet telephony adds additional complications. Complications arise since functionality tends to be more distributed, users can program the behavior of end systems and signaling systems, the distinction between end systems and network equipment largely vanishes and the trust model implicit in the PSTN architecture no longer holds. On the other hand, Internet telephony makes end point addresses plentiful and its signaling makes it easy to specify in detail the desired network behavior. Many techniques for resolving interactions in the PSTN are no longer easily applied, but several new techniques, explicitness, authentication, and verification testing, become possible in the Internet environment.
