Internet has penetrated into our very lifestyle and has become an essential part of our daily requirement. From on line buying and selling to searching for every possible information; the World Wide Web provides us all. Internet’s latest offering is voice over IP service which has changed the very way communication was perceived. Initially VoIP or voice over IP was not given a warm welcome. Much of it had to do with the fact that high speed Internet which is essential for call transmission was not easily available to one and all. With changing times this scenario has drastically changed. High speed broadband service has become a reality in the contemporary times with every nook and corner having a cyber-cafe and 2 out of 3 houses equipped with high speed Internet service.
Voice over IP call termination service has brought along with it bounteous leverages which makes it the preferred choice of many. It is the most cost effective method of making calls. Long distance and International calling through it can be made at a much cheaper rate thereby allowing you to save with every call that you make. Finally you have a reason to keep talking!
Besides this, Voip services provide enhanced quality with number of improvements being made in this field over a period of time. It increases the overall efficiency since it helps transmit voice, data and video all through a single channel i.e. via Internet. This in turn will have a direct positive effect on the productivity of your organization.
One of the best parts of using branded voice over IP service is that it provides ease of operations. You can make VoIP calls through your computer if it has an Internet connection by using a headset. However, if you are comfortable using fixed line telephones that we have been using till now, then VoIP facilitates that too. You can simply attach an ATA (analogue adapter) along with your regular phone and make calls exactly the way you used to at much cheaper rates. Life couldn’t get better!

Hacking Voip $27.97 Voice Over Internet Protocol (VoIP) networks, the technology used to place phone calls through the Internet, suffer from the same security holes as standard IP networks, as well as new threats specific to telephony. In addition to attacks on network availability and authentication, administrators must contend with eavesdropping, audio injection, Caller ID spoofing, VoIP phishing, and other unique exploits. All of these security holes can result in the leakage of information and in unreliable phone calls. Hacking VoIP reviews the many possible VoIP attacks, and discusses the best defenses against them for both enterprise and home VoIP solutions. Author Himanshu Dwivedi introduces popular security assessment tools, describes the inherent vulnerabilities of common hardware and software packages, and provides the first ever VoIP security audit program. The book covers common enterprise VoIP protocols such as SIP and RTP as well as unique protocols like H.323 and IAX. |

Switching to VoIP $26.36 More and more businesses today have their receive phone service through Internet instead of local phone company lines. Many businesses are also using their internal local and wide-area network infrastructure to replace legacy enterprise telephone networks. This migration to a single network carrying voice and data is called convergence, and it’s revolutionizing the world of telecommunications by slashing costs and empowering users. The technology of families driving this convergence is called VoIP, or Voice over IP. VoIP has advanced Internet-based telephony to a viable solution, piquing the interest of companies small and large. The primary reason for migrating to VoIP is cost, as it equalizes the costs of long distance calls, local calls, and e-mails to fractions of a penny per use. But the real enterprise turn-on is how VoIP empowers businesses to mold and customize telecom and datacom solutions using a single, cohesive networking platform. These business drivers are so compelling that legacy telephony is going the way of the dinosaur, yielding to Voice over IP as the dominant enterprise communications paradigm. Developed from real-world experience by a senior developer, O’Reilly’s Switching to VoIP provides solutions for the most common VoIP migration challenges. So if you’re a network professional who is migrating from a traditional telephony system to a modern, feature-rich network, this book is a must-have. You’ll discover the strengths and weaknesses of circuit-switched and packet-switched networks, how VoIP systems impact network infrastructure, as well as solutions for common challenges involved with IP voice migrations. Among the challenges discussed andprojects presented: building a softPBX configuring IP phones ensuring quality of service scalability standards-compliance topological considerations coordinating a complete system ?switchover? migrating applications like voicemail and directory services retro-interfacing to traditional telephony supporting mobile users security and survivability dealing with the challenges of NAT To help you grasp the core principles at work, Switching to VoIP uses a combination of strategy and hands-on how-to that introduce VoIP routers and media gateways, various makes of IP telephone equipment, legacy analog phones, IPTables and Linux firewalls, and the Asterisk open source PBX software by Digium. You’ll learn how to build an IP-based or legacy-compatible phone system and voicemail system complete with e-mail integration while becoming familiar with VoIP protocols and devices.
