Voice over Internet Protocol (VoIP) is gaining a lot of attention these days, as more companies and individuals switch from standard telephone service to phone service via the Internet. The reason is simple: A single network to carry voice and data is easier to scale, maintain, and administer. As an added bonus, it's also cheaper, because VoIP is free of the endless government regulations and tariffs imposed upon phone companies.

VoIP is simply overflowing with hack potential, and VoIP Hacks is the practical guide from O'Reilly that presents these possibilities to you. It provides dozens of hands-on projects for building a VoIP network, showing you how to tweak and customize a multitude of exciting things to get the job done. Along the way, you'll also learn which standards and practices work best for your particular environment. Among the quick and clever solutions showcased in the book are those for:

• gauging VoIP readiness on an enterprise network
• using SIP, H.323, and other signaling specifications
• providing low-layer security in a VoIP environment
• employing IP hardphones, analog telephone adapters, and softPBX servers
• dealing with and avoiding the most common VoIP deployment mistakes

In reality, VoIP Hacks contains only a small subset of VoIP knowledge-enough to serve as an introduction to the world of VoIP and teach you how to use it to save money, be more productive, or just impress your friends. If you love to tinker and optimize, this is the one technology, and the one book, you must investigate.

Voice over Internet Protocol (VoIP) networks have freed users from the tyranny of big telecom, allowing people to make phone calls over the Internet at very low or no cost. But while VoIP is easy and cheap, it's notoriously lacking in security. With minimal effort, hackers can eavesdrop on conversations, disrupt phone calls, change caller IDs, insert unwanted audio into existing phone calls, and access sensitive information.

Hacking VoIP takes a dual approach to VoIP security, explaining its many security holes to hackers and administrators. If you're serious about security, and you either use or administer VoIP, you should know where VoIP's biggest weaknesses lie and how to shore up your security. And if your intellectual curiosity is leading you to explore the boundaries of VoIP, Hacking VoIP is your map and guidebook.

Hacking VoIP will introduce you to every aspect of VoIP security, both in home and enterprise implementations. You'll learn about popular security assessment tools, the inherent vulnerabilities of common hardware and software packages, and how to:

• Identify and defend against VoIP security attacks such as eavesdropping, audio injection, caller ID spoofing, and VoIP phishing
• Audit VoIP network security
• Assess the security of enterprise-level VoIP networks such as Cisco, Avaya, and Asterisk, and home VoIP solutions like Yahoo! and Vonage
• Use common VoIP protocols like H.323, SIP, and RTP as well as unique protocols like IAX
• Identify the many vulnerabilities in any VoIP network

Whether you're setting up and defending your VoIP network against attacks or just having sick fun testing the limits of VoIP networks, Hacking VoIP is your go-to source for every aspect of VoIP security and defense.
