This book explores issues posed by convergent voice and data networks, and considers future scenarios as Internet telephony continues to alter the communications landscape.

Since the publication of the first edition, the CTI world has changed significantly. Where it was once focused on the integration of voice systems with computers, the focus is now on IP-based voice, or converged networks and services. Today, the telcos are upgrading their systems from circuit-switched to IP-based packet-switched networks. Companies

A TAPI tutorial for the Windows C++ developer, including several applications and a C++ class library developed to make Windows telephony more accesible. The key audiences are Windows developers and telephony programmers.

The real-world guide to securing Cisco-based IP telephony applications, devices, and networks Cisco IP telephony leverages converged networks to dramatically reduce TCO and improve ROI. However, its critical importance to business communications and deep integration with enterprise IP networks make it susceptible to attacks that legacy telecom systems did not face. Now, there’s a comprehensive guide to securing the IP telephony components that ride atop data network infrastructures–and thereby providing IP telephony services that are safer, more resilient, more stable, and more scalable. Securing Cisco IP Telephony Networks provides comprehensive, up-to-date details for securing Cisco IP telephony equipment, underlying infrastructure, and telephony applications. Drawing on ten years of experience, senior network consultant Akhil Behl offers a complete security framework for use in any Cisco IP telephony environment. You’ll find best practices and detailed configuration examples for securing Cisco Unified Communications Manager (CUCM), Cisco Unity/Unity Connection, Cisco Unified Presence, Cisco Voice Gateways, Cisco IP Telephony Endpoints, and many other Cisco IP Telephony applications. The book showcases easy-to-follow Cisco IP Telephony applications and network security-centric examples in every chapter. This guide is invaluable to every technical professional and IT decision-maker concerned with securing Cisco IP telephony networks, including network engineers, administrators, architects, managers, security analysts, IT directors, and consultants. Recognize vulnerabilities caused by IP network integration, as well as VoIP’s unique security requirements Discover how hackers target IP telephony networks and proactively protect against each facet of their attacks Implement a flexible, proven methodology for end-to-end Cisco IP Telephony security Use a layered (defense-in-depth) approach that builds on underlying network security design Secure CUCM, Cisco Unity/Unity Connection, CUPS, CUCM Express, and Cisco Unity Express platforms against internal and external threats Establish physical security, Layer 2 and Layer 3 security, and Cisco ASA-based perimeter security Complete coverage of Cisco IP Telephony encryption and authentication fundamentals Configure Cisco IOS Voice Gateways to help prevent toll fraud and deter attacks Secure Cisco Voice Gatekeepers and Cisco Unified Border Element (CUBE) against rogue endpoints and other attack vectors Secure Cisco IP telephony endpoints–Cisco Unified IP Phones (wired, wireless, and soft phone) from malicious insiders and external threats This IP communications book is part of the Cisco Press® Networking Technology Series. IP communications titles from Cisco Press help networking professionals understand voice and IP telephony technologies, plan and design converged networks, and implement network solutions for increased productivity.

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.

IP (internet protocol) Telephony, enabled by softswitches, isgoing to usher in a new era in telecommunications. By putting voiceand data over one IP network, operators can enjoy lower costs andcreate new, revenue-generating "multimedia" services. This valuable reference offers a comprehensive overview of thetechnology behind IP telephony and offers essential information tonetwork engineers, designers and managers who need to understandthe protocols and explore the issues involved in migrating theexisting telephony infrastructure to an IP-based real timecommunication service. Drawing on extensive research and practical developmentexperience in VoIP from its earliest stages, the authors giveaccess to all the relevant standards and cutting-edge techniques ina single resource. IP Telephony: Deploying Voice-over-IP Protocols: Assumes a working knowledge of IP and networking and addressesthe technical aspects of real-time communication over IP. Presents a high level overview of packet media transporttechnologies, covering all the major VoIP protocols – SIP,H323 and MGCP Details specific strategies to design services for publicnetworks where endpoints cannot be trusted and can be behindfirewalls. Explores the problems that may arise from incomplete protocolimplementations, or architectures optimized for private networkswhich fail in a public environment. This amply illustrated, state-of-the art reference tool will bean invaluable resource for all those involved in the practicaldeployment of VoIP technology.
