Ce livre sur la voix sur IP (VoIP et ToIP) est destiné aux acteurs du domaine des systèmes, réseaux et télécoms d'entreprises, ainsi qu'à toute personne souhaitant découvrir et comprendre ce domaine de la Voix sur IP. Il s'adresse également aux décideurs informatiques qui doivent faire évoluer leur architecture de téléphonie. Il permet de détailler toutes les étapes de la mise en place de l'autocom Open Source Asterisk, de la conception-architecture à la mise en production. La démarche progressive des différents chapitres permet d'aborder toutes les étapes indispensables pour mettre en production une T-VoIP autour d'Asterisk : du choix de l'architecture cible à la mise en œuvre d'un call center, en passant par l'installation du serveur, le choix des passerelles opérateurs, la nécessaire préparation du réseau, la mise en place d'un plan de numérotation éprouvé, l'interconnexion de sites distants et l'utilisation potentielle d'outils supplémentaires pour enrichir les fonctionnalités du PBX. Tous les sujets sont présentés avec de nombreux exemples pratiques. Des connaissances sur l'administration d'un système Linux sont souhaitables pour tirer le meilleur profit de cet ouvrage.

A guide to successful deployment of the Cisco IP Telephony solution Real-world case studies from the Cisco design consulting engineers who developed the PDIOO process provide practical advice on all stages of successful IPT deployment Concise understanding of the PDIOO phases enables architects and engineers to successfully deploy the Cisco IPT solution Division of the process into PDIOO phases provides a logical and defined guide for network engineers and architects as they proceed through each of the phases in deploying the Cisco IPT solution Includes detailed questionnaires for each phase of deployment in the PDIOO cycle—a great aid in understanding customer networks and requirements Network infrastructure design, call processing infrastructure design and applications, and voice-mail system design are covered in depth Cisco® IP Telephony (IPT) solutions are being deployed at an accelerated rate, and network architects and engineers need to understand the various phases involved in successful deployment: planning, design, implementation, operation, and optimization (PDIOO). On the road to that understanding, those involved need to collect information for each phase of deployment, and then follow through with the best architecture, deployment model, and implementation based on the data collected. Cisco IP Telephony: Planning, Design, Implementation, Operation, and Optimization is a guide for network architects and engineers as they deploy the Cisco IPT solution. With this book, you will master the PDIOO phases of the IPT solution, beginning with the requirements necessary for effective planning of a large-scale IPT network. From there, you’ll follow a step-by-step approach to choose the right architecture and deployment model. Real-world examples and explanations with technical details, design tips, network illustrations, and sample configurations illustrate each step in the process of planning, designing, implementing, operating, and optimizing a chosen architecture based on information you have collected. In-depth instruction on each PDIOO phase provides specific details about the tasks involved and best practices for successful implementation of the IPT solution. This book also contains predesigned questionnaires and PDIOO assistance tools that help you determine the requirements of each phase of the PDIOO cycle. Authors Ramesh Kaza and Salman Asadullah have been involved with Cisco IPT solutions from the beginning and have planned, designed, and implemented major IPT networks using the guidelines found here. Cisco IP Telephony: Planning, Design, Implementation, Operation, and Optimization provides the step-by-step explanations, details, and best practices acquired by the authors while working with the top Cisco IPT customers. This book is part of the Networking Technology Series from Cisco Press®, which offers networking professionals valuable information for constructing efficient networks, understanding new technologies, and building successful careers.

La voix sur LTE (Long Term Evolution) présente les mécanismes mis en oeuvre dans le réseau de mobiles 4G pour le transport de paquets IP contenant la voix et la signalisation téléphonique, ainsi que les technologies utilisées pour la fourniture du service téléphonique dans le réseau IMS (IP Multimedia Sub-system). Malgré la difficulté liée au handover du réseau 4G vers le réseau 2G/3G, l’établissement d’une communication téléphonique ne sera pas réalisé sur un réseau 4G. Cet ouvrage analyse les technologies mises en oeuvre, comme le CSFB, solution d’attente qui permet à un mobile attaché au réseau 4G de recevoir une alerte (paging) transmise par le réseau 2G/3G. Le protocole SIP sur lequel se base la signalisation téléphonique transférée par le réseau 4G, le réseau IMS qui fournit le service et définit le routage, le mécanisme SRVCC qui assure le maintien de la communication et le serveur d’applications TAS, sont également développés. L’auteur Consultant et formateur en réseaux et télécommunications, intervient auprès des industriels et des opérateurs sur des études d’architecture. Il anime des formations sur les réseaux 4G et IMS pour NEXCOM.

ORACLE 11G: SQL is an introduction to the fundamental SQL language used in all relational databases today. This textbook is not simply a study guide; it is written for those who have just a basic knowledge of databases and can be used in a course on this latest implementation of SQL from Oracle. Learning these concepts and techniques prepares students for the first exam in both the Oracle Database Administrator and Oracle Developer Certification Exam paths and offers a solid understanding of using Oracle 11g SQL effectively. The first part of ORACLE 11G: SQL focuses on creating database objects, including tables, constraints, indexes, sequences, synonyms, and users, and manipulating data. The second part explores data query techniques, such as row filtering, joins, single-row functions, aggregate functions, subqueries, and views. Several advanced query topics, such as ROLLUP, CUBE, and TOP-N analysis, are also introduced. To help students bridge these SQL topics to further studies, appendixes introduce SQL tuning, compare Oracle’s SQL syntax with other databases (MS SQL Server and MySQL), and explain how to embed SQL in applications (ASP.NET). An overview of the two Oracle connection interface tools, SQL Developer and SQL Plus, is also provided. Important Notice: Media content referenced within the product description or the product text may not be available in the ebook version.
