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 realize 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 addition 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.
VoIP Phone systems - a step above traditional phone lines
The words are; cost effective, portable, and flexible. And hey it comes with array additional new features too! No it is not our regular PSTN phone connection. The buzz word here is; VoIP phone systems.
It is the technology that transfers your voice from over the internet using specially designed call signal protocols in a much efficient manner. Efficient in terms of its low cost, the number of additional features that it offers , the convenience with which the call can be placed from anywhere at any time and for as long as you want !
The advent of the internet, bought the world closer. And it swept each one of us by our feet and today we are completely dependent on it for our day to day activities. Walking a step closer VoIP system has been developed! And it will completely revolutionarise the traditional way of making phone calls.
It’s smart, convenient, cost effective and absolutely relevant with the times we live in. How much on an effort is it, to switch on your laptop and make a call! Practically nothing! While at the same time it offers us a chance to talk for as long as we want without having to worry about the long bills!
Traditional analogue phones are a lengthy network of wires used to facilitate calling from one end to the other, and while a call takes place that particular wire system is dedicated to that one call. This is the reason; phone bills are higher on international calls. While VoIP Phones Systems work on the broadband connections. Once a call is dialed the analogue voice data is converted into small packets of digital audio data and transferred using special internet protocols from one end to the but delivered to the person in a comprehendible analogue format
Truly VoIP telephony is a step above the traditional phone lines and not far from now it would completely change the way we make long distance calls!
VoIP Communication
VoIP communication – this is the new lingo of the telecommunication industry and it promises to revolutionaries the entire scenario of today’s communication.
Popularly known as VoIP, it means voice over internet protocol. Quite literally, this is what it really does also!
A new paradigm of communication! From the time when man used the strangest of ways to communicate to one another, using sounds, clay tablets, sign language and a lot of other stuff to a present day world where two people sitting miles across can get in touch, chat or even be visible to each other at the drop of a hat! Certainly it’s been a long – long journey for us.
VoIP technology, cashes on the access to high speed internet available to common man. With the advent of broadband, several high end applications have been specially developed to render quality services and one such, is VoIP technology.
VoIP technology has the potential to upheaval the dominance of PSTN phones within no time. VoIP facilitates audio communication completely negating factors like distance, time and money!
Sounds tempting doesn’t it! But this is no mirage. VoIP doesn’t function like conventional phone lines. It is a by product of contemporary minds, who devised a way of transferring audio data in small packets via broadband internet from one network to the other , bringing down the calling charges to minimal subscription fees.
If simply put- It is the technology used and the cost factor that gives VoIP an edge over others.
The Companies offering VoIP services, sell contract packages, mostly with in-built features like free voice mails, caller ID, call waiting, call forwarding, 3 way calling, speed dialing which to the end user are free of cost. Besides the low calling rates, value added services like these make VoIP technology almost impossible to be ignored.
VoIP redefines the way we have looked at communication.
VoIP Fax
It’s only a matter of time before technology brings to us reliable faxing VoIP codec. As far as VoIP goes, the speed with which it has chiseled through our lives, sweeping us of our feet; it reinstates our faith in it and asserts that Faxing over VoIP technology will soon be a phenomenal hit too!
The basis issues over VoIP faxes are that unlike VoIP, VoIP fax functions on a different codec. While trying to send faxes through VoIP we basically have two different codec’s running, one which supports VoIP and the other which supports the fax. That’s the reason why VoIP service providers include a free additional fax line with special faxing codec’s to allow and propagate the idea of Faxing over VoIP
The reason why faxing has not picked up popularly over the VoIP technology is the basic issue of data loss or damage. Basically how VoIP technology functions is that it coverts analogue signals into digital and transfer them in the shape of small packets over a high speed broadband line.
Now when the fax tone is digitized into packets and transferred from the VoIP server these packets are often lost or damaged. Packets are lost over a VoIP call too, but this loss is still manageable as the voice can still be interpreted and understood but when it happens to the data packets of a fax, the data lost makes for a message that is non comprehendible and can really mess up the fax and result in bad fax , dropped calls or error messages.
However using fax codec, chances of proper delivery of data is greater however chances of failure increase if the number of pages increases from more than 10.
A common practice is to scan the fax copy in to a .PDF file and email it across simultaneously while using VoIP fax.
Such limitations of VoIP faxing have hampered its course of acceptability; however it’s too early to conclude the fate of this technology as it is in its nascent stage.
VoIP Call
VoIP telephony is here to revolutionaries the world of telecommunication making dedicated phone lines and long bills a thing of past. On the façade of VoIP endorsement, has been long distance calls, which have been reduced to easy calling, which is just a click away! That too with no charges replicating the bill of an over seas call...
VoIP technology speaks the lingo of the 21st century. Smart, inexpensive and efficient and backs on the internet to facilitate it – for its stands for voice over internet protocol.
Though VoIP is still a very recent phenomenon its still has managed to have swept us all by our feet. The reason that can be credited to the popularity of VoIP is the provision of making long distance calls at a very cheap rate along with n array of value added services that a VoIP subscriber receives plus the good quality of a call.
The quality of a VoIP call, though depends of several factors which should be kept in mind while setting up a VoIP system
Basically a VoIP call gets through with a broadband internet connection through which audio signals are digitalized into small packets and transferred at high speed. A VoIP call can be placed in several ways like; by using an analogue digital adaptor, broadband phone or a wireless phone.
To ensure the good quality of a call make sure
The broadband internet connection being used in, high in quality and provides good connectivity speeds. The hardware installed with a broadband connection like a modem and a splitter should be of good quality too
While connecting to the internet, the quality of the broadband phone, or the adaptor, the head sets should all be taken into consideration.
Several broadband providers today assign special call signal protocols like H.232 and SIP which are designed to facilitate VoIP traffic efficiently. These are a good alternative to the regular ISP`s for they provide services specially facilitating the requirements of VoIP users.
Virtual Private networks are a common practice amongst corporate’s who, create private networks to follow the flow of communication amongst themselves, forbidding any intrusion attempts with strong encryptions and firewalls. VPN`s ensure safe transfer of data and prohibit attempts of eavesdropping or data sniffing
Anyone who gives a serious thought to using VoIP technology should lay emphasis on the quality of the output. The quality of a call in as important as reduced bills. However it greatly depends on the steps on takes to ensure god services; like the quality of the hardware used for both broadband and VoIP and adopting special call protocols and private networks to keep the flow of calls smooth and the quality of a VoIP call supreme
VoIP Gateway
Though the output of this technology is captivating and intriguing but the fact is that VOIP technology works on a very basic principle. It is hard to believe that a technology that facilitates voice communication between two distant ends of the world easily is comprehendible.
However it is the fact.
VoIP stands for Voice over the Internet Protocol. A phone call made from one end of the world to the other, using the internet as a route instead of the dedicated phone lines is what VoIP technology does. And the flavor of internet connection used for such a purpose can be nothing else but a high speed broadband connection. The internet works in a very organized manner, with a job deployed to each member of a team, like a router, a modem a cable a gateway etc!
Off course a gateway of the virtual world sounds intriguing! While VoIP digitalizes analogue data into small packets to be transferred to the World Wide Web and vice versa, the flow of packets /data needs to be disciplined and streamed in a manner that it reaches the required destination for which routers, gateways, IP addresses are installed.
Depending on the requirement of a particular system a VoIP gateway can be installed as either a digital or analogue device within a router or a separate dedicated device. It is used to process the inflow and outflow of data from a virtual gateway. A VoIP gateway connects to the data network via Ethernet or WAN and converts the outgoing voice data received into IP packets suitable for transmission and incoming data into a stream of comprehendible data that can be used by the PBX system
VoIP gateways are special because they discipline the flow of audio data and convert them from digital to analogue and vice versa. Thereby rendering the proper channeling all data possible, this in turn makes use of VoIP really worthwhile!
