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

Introduction
The days of staring at a mess of wires under the desk coming out of a PSTN Master Socket are truly over. The advent of VoIP has broken the stranglehold of a telephone cable and the network has finally taken over. I would not say that IP Telephony has revolutionised the telephony sector. That momentous transition happened years ago. We currently are going through a phase where it is common to have IP Telephony integrated into any enterprise and network administrators are actively implementing security measures and policies to it. Network security is of paramount importance and IP Telephony is not to be left behind. The fact is that Cisco, the market leader in network technology, also happens to be leading the IP Telephony field. Hence it has rightly decided that establishing robust security architecture is core to Cisco IP Telephony.
The latest Cisco title addresses the aforementioned issue promptly and efficiently. Whenever a technology becomes efficient, scalable and portable and is seen as an improvement on the incumbent technology, it is deemed indispensable. From that moment it also becomes a point of failure that can cripple a business because it has now inherited security vulnerabilities and threats. The same can be said about Cisco IP Telephony. What this books aims to achieve is, and I quote, "to explain an End-to-End IP Telephony Security approach and architecture..." And I assure you, this title does plenty of justice to that aim. So let's dig deeper into the way this book deals with the issues and how it tackles security policies, principles and their respective implementations.
