.: Is Your VOIP Service Secure?
By:Ron King
Category:Home / Technology / VOIP
For individuals, VOIP security is primarily a matter of preventing others from eavesdropping on their conversations. Some VOIP service providers offer voice security through encryption or separate data routes.
Regular precautions for transferring files should, of course, always be followed. A firewall should be in place for protecting your computer from the internet and any data or program that is downloaded should be checked for viruses.
But users should reealize that VOIP hardware devices are inherently more vulnerable to attack. Some types of equipment can be made unstable or inoperable when they receive certain types of data. Some internet phones are also susceptible to data piracy, revealing private information under certain conditions.
While this probably won't be of much concern when you're calling Uncle Tim, it is a huge concern for businesses that consistently use telephone communication for discussing sensitive business information. As VOIP popularity increases, security is becoming a growing concern and is now receiving widespread attention.
Security Issues
It's mainly businesses that need to be concerned with security issues related to VOIP. They are more susceptible to the Denial of Service (DOS) attacks and other forms of obnoxious hacking because many businesses operate personal gateways and other equipment for connecting to the internet.
There are several security issues associated with VOIP. Eavesdropping is an understandable fear with both regular and VOIP calls, but there are additional concerns unique to this technology. Since VOIP data is traveling across the internet just like any other kind of data, it is vulnerable to the same types of attacks. Hackers have countless software tools available to them to retrieve information being transmitted over the internet. These tools are as effective with voice data as with any other kind of data.
Another security threat is the possibility of sending viruses with VOIP data. This hasn't surfaced yet, but viruses could potentially overload VOIP networks, reduced sound quality and create delays.
VOIP isn't secure against spam either. This refers to receiving unsolicited marketing calls from companies selling their goods and services.
There are several points in the transmission of VOIP calls that hackers can use to recover information. In additin to retrieving actual conversations, they can also access critical information such as user identities and VOIP phone numbers. With this information, a hacker can place phone calls using someone else's identity.
Attackers could also record phone calls while eavesdropping on conversations and even potentially restructure voice data to create discussions that never actually existed! Log files could also be accessed and altered.
There are ways currently available that address such security issues. The first is with encryption that provides the same sort of security used in sending credit card information over a secure data connection. The second is to separate VOIP data from other internet traffic by using a Virtual Local Area Network (VLAN). Both methods can degrade call quality, but they present an alternative for sensitive calls.

1). VoIP Problems?
Well of course there's VoIP problems, although I think problems is too strong of a word. Instead I would call this VoIP issues. (Just semantics? maybe, read on!)
Some may be old enough to remember making long distance calls where there was static or crackling on the phone line connection. Maybe you remember having to speak LOUDER in order to be heard on the line.
2). How To Set Up A Business VoIP System
To set up a business VoIP system, you need several components. A central device to manage the calls, the way a private branch exchange (PBX) or key system unit (KSU) does in traditional phone systems is one of them.
This can be a dedicated piece of hardware such as an IP PBX, a regular PBX that has been IP-enabled, or a server running specialized software.
3). VoIP Information: Benefits & Drawbacks
Once upon a time, a telephone was just a telephone. You set the base in your home and it featured either a corded or cordless handset for talking to family and friends. Even though that same telephone remains the standard, VoIP, which stands for Voice over Internet Protocol, is increasing in popularity and gradually beginning to change the way that the world sends and receives telephone calls.
4). Skype versus Yahoo
With the influx of complaints regarding Skype’s fall from grace, Danny Wirken measures up the top competitor and internet giant Yahoo!’s news internet telephony service.
Cheaper, faster, better quality, better customer service and a brand you can trust. These are the things Yahoo! want you take away from any of their promotional material for the new Yahoo! voice VoIP service.
5). Voice Over Ip – What Is It And What Are The Choices?
Voice over Internet Protocol. First was the telephone. Alexander Graham Bell had a vision. He saw people communicating over long distances with their own voice, not trough beeps and squeaks. Then came the Internet. A few students and the US military had a vision, somewhat similar to Bell’s. They saw people communicating over long distances, but this time in writing.
6). Why VOIP?
Voice Over Internet Protocol delivers the service of converting the analog line into a digital signal so that voice could be transferred through the internet and this proves to be a lot cheaper than the PSTN (public switched telephone network). Voip is the best for making long distance calls in, inexpensive rates.
Voip and IP telephony are fields which have seen extensive growth and they continue to develop efficiently.
7). Advanced VoIP Gateway Technology
Increased demand for video-based applications in the mobile network drive the deployment of 3G networks. Inherent complexities in traditional video gateways cause performance bottlenecks and inflate costs. If the industry expects to absorb the impending explosion in demand, these proposed cost-saving and complexity-reducing changes are needed.
Unrelenting market demand for video-based applications over mobile networks is driving the increased deployment of 3G networks.
