Download or read book Cisco Voice Gateways and Gatekeepers written by David Mallory and published by Pearson Education. This book was released on 2006-08-17 with total page 741 pages. Available in PDF, EPUB and Kindle. Book excerpt: Deployments of voice over IP (VoIP) networks continue at a rapid pace. Voice gateways are an essential part of VoIP networks, handling the many tasks involved in translating between transmission formats and protocols and acting as the interface between an IP telephony network and the PSTN or PBX. Gatekeepers and IP-to-IP gateways help these networks scale. Gatekeepers provide call admission control, call routing, address resolution, and bandwidth management between H.323 endpoints including Cisco IOS® voice gateways and Cisco® Unified CallManager clusters. IP-to-IP gateways allow VoIP calls to traverse disparate IP networks. Cisco Voice Gateways and Gatekeepers provides detailed solutions to real-world problems encountered when implementing a VoIP network. This practical guide helps you understand Cisco gateways and gatekeepers and configure them properly. Gateway selection, design issues, feature configuration, and security and high-availability issues are all covered in depth. The abundant examples, screen shots, configuration snips, and case studies make this a truly practical and useful guide for anyone interested in the proper implementation of gateways and gatekeepers in a VoIP network. Emphasis is placed on the accepted best practices and common issues encountered in real-world deployments. Cisco Voice Gateways and Gatekeepers is divided into four parts. Part I provides an overview of an IP voice network. Part II is dedicated to voice gateways, including discussions of Media Gateway Control Protocol (MGCP); H.323; Session Initiation Protocol (SIP); voice circuit options; connecting to the PSTN, PBX, and IP WAN; dial plans; digit manipulation; route selection; class of restriction; Survivable Remote Site Telephony (SRST) and MGCP fallback; digital signal processor (DSP) resources; and Tool Command Languaue (Tcl) scripts and Voice XML (VXML). Part III addresses voice gatekeepers, including detailed deployment and configuration. Part IV is dedicated to IP-to-IP gateways.

Book excerpt: Configuring Cisco Voice Over IP, Second Edition provides network administrators with a thorough understanding of Cisco's current voice solutions. This book is organized around the configuration of all of Cisco's core VoIP products, including Cisco CallManager software, Cisco 7910 series of phones, and server-based IP PBXs. In addition, AVVID coverage has been added.An update to a bestselling title in a growth market. Continued competitive pressure on ISPs to deliver VoIP will create strong demand information on topicVoice Over IP is expected to make great inroads in 2002. Voice-over-IP got its start at the time of the first edition of the book; it is now real and more companies are adopting it since IT managers have become less skeptical of IP telephony's reliability and more aware of the potential cost savings and application benefits of a converged network. Voip wares now promise easier quality-of-service (QoS) deployment, and a multitude of new IP phones and conferencing stations for corporations.Cisco and IBM recently announced a package deal that could help businesses quickly roll out IP voice in a small or midsize office. Since getting into the IP telephony market two years ago, Cisco has seen quick success in selling its voice-over-IP products into its vast installed base of IP LAN equipment customers. The firm was the top vendor of IP phones in the first quarter of this year and second in IP PBX system shipments (behind 3Com), according to Cahners In-Stat.

Available in PDF, EPUB and Kindle. Book excerpt: In The Implosion of Capitalism world-renowned political economist Samir Amin connects the key events of our times - financial crisis, Eurozone implosion, the emerging BRIC nations and the rise of political Islam - identifying them as symptoms of a profound systemic crisis.In light of these major crises and tensions, Amin updates and modifies the classical definitions of social classes, political parties, social movements and ideology. In doing so he exposes the reality of monopoly capitalism in its contemporary global form.In a bravura conclusion, Amin argues that the current capitalist system is not viable and that implosion is unavoidable. The Implosion of Capitalism makes clear the stark choices facing humanity - and the urgent need for a more humane global order.
