Voice Over IP: Systems and Solutions

admin — Thu, 25 Nov 2010 14:32:46 +0000

Product Description
This book covers all aspects of telephony over IP networks, known as Voice over IP (VoIP). VoIP hit the headlines during the mid-1990′s amid claims concerning its impact upon existing Switched Circuit telephony services. Whilst VoIP has clearly provided a focus for much debate within the telecommunications industry, there has been a clear gulf between hype and reality. This book examines VoIP as a technology and its consideration within the industry, the motivations for VoIP networks, a review of the status of the major components of a VoIP network and their development, and both current and emerging applications. This makes for essential reading for those with a technical or business interest in this rapidly developing area of telecommunications.Also available:Telecommunications Network Modelling, Planning and Design – ISBN 0863413234

Product Description
Voice over IP Security Security best practices derived from deep analysis of the latest VoIP network threats Patrick Park VoIP security issues are becoming increasingly serious because voice networks and services cannot be protected from recent intelligent attacks and fraud by traditional systems such as firewalls and NAT alone.

Another type of security issue is how to implement lawful interception within complicated service architectures according to government requirements. Voice over IP Security focuses on the analysis of current and future threats, the evaluation of security products, the methodologies of protection, and best practices for architecture design and service deployment.

Article Source: http://www.articlesbase.com/ – VoIP security – more and more important

VoIP security is more and more essential for both organizations and those providers delivering VoIP products. To date VoIP security has not been an important problem, since IP voice traffic generally stayed on local enterprise networks. But since VoIP usage is becoming more and more more generally used, this has raised worries over the VoIP security situation.

Furthermore, for all kinds of companies, it’s rather demanding for already busy IT staff to ensure that VoIP security strategies keep pace with newly discovered dangers to their VoIP network.

Yet, in their eagerness to merge the organization’s voice and data networks and hence trim telephony bills, many companies are failing to correctly consider VoIP’s single drawback: security.

VoIP is characterized by a union of the conventionally separate voice and data networks. The VoIP technology is still new and so far the actual attacks have been negligible. But a new sense of exigency is developing with the dangers of wide spread security violation as VoIP technology is gaining market.

By now, just about everybody is concerned about the demand for packet data encryption to protect VoIP traffic. This means controlling the network for dubious activities, as well as preserving the operating system and VoIP programs.

To fight back threats on VoIP security systems it is crucial to first work out a technique of sending VoIP traffic through firewalls and other essential security measures. Until then we are all predisposed to security breaches like denial of service attacks, tapping and loss of information in general.

Secure your VoIP platform in the sense that the VoIP traffic should be operated by independent servers with controlled access, even considering putting the VoIP systems out of direct access from the Internet. Also the use of VPN-tunneling for the VoIP communication should certainly be considered. Renovate patches often – the security of a VoIP network depends on both the main operating systems and the applications that run on it.

Spamming of all kinds has made its way into our daily lives, and VoIP is beyond doubt no exception. VoIP spamming is even seen as more irritating than email spamming. Along with the continuously increasing popularity of VoIP spamming, spammers have found yet another medium to take advantage of – the VoIP Voicemail – since the technology to apply VoIP spamming regrettably is rather straightforward to grasp.

With a bit of luck and with a decent focus on safety measures, attacks such as VoIP spamming, call redirection and VoIP interception and fake Caller IDs will decrease before VoIP becomes the real communication standard. Without hesitation, VoIP communications can be made more secure and trustworthy than regular PSTN interactions on condition that the right security measures are taken within the organization.

To VoIP, Or Not to VoIP: That is the Question

To VoIP, Or Not to VoIP: That is the Question

VoIP has become a popular network application in the last few years in the internet and communication world. While it brings major benefits for both consumers and businesses that use it, the decision of whether VoIP is right for their needs is a difficult one. Many businesses may not know the benefits of VoIP either.

Consumers and businesses are aware that implementing a VoIP network can save them money. For those that make a lot of long distance calls, the savings increase substantially. For those that wonder how the savings occur, you first have to understand how VoIP works. VoIP calls are transmitted along your broadband internet connection, bypassing your regular telephone service provider. The cost-savings are from not being charged the numerous taxes and other charges that your regular phone line incurs.

Saving money from long distance calls can result in a massive savings for businesses. With the growing number of VoIP service providers entering the market each year, the competition and subsequent pricing battle between the providers, now is a good time for many businesses looking to convert to VoIP.

With the deployment of a VoIP network into your business, you will receive a converter. This converter is great in itself because it’s assigned with your own individual number. If you need to travel, you just take the converter with you and plug it into any broadband connection. This allows you to make and receive calls using the same number. Make sure to have a good bandwidth connection, such as with broadband or DSL, to ensure your VoIP will work successfully. Other things you will need include a computer microphone or regular phone, a VoIP route adaptor for connecting to the internet and of course, a VoIP service provider.

Features that come with a VoIP network include call waiting, caller ID, speed dialing, call forwarding, 3-way calling, free voicemail, plus much more.

In summary, there are many benefits for your business to convert to a VoIP network. While the decision of whether VoIP is right for your business’s needs is a difficult one, hopefully this article has helped you make a better decision. What business doesn’t want to stay ahead of their competition AND save money? This decision is yours! Just be sure to compare the services and costs of several carriers first, then choose the one that best suits your business’s needs. Do your homework first!
