This article contains the excellent information about the Voice Over IP Protocol.
Voice over Internet Protocol (VoIP) technology is the wave of the future in terms of telephone communication via the Internet. VoIP has several advantages over circuit-switched technology used by local phone companies. Circuit-switched technology uses a ‘permanent’ connection between the caller and callee, which requires a huge amount of bandwidth for each call.
This type of technology can only carry certain types of calls, such as telephone to telephone. Also, the hardware circuit-switched networks need to run effectively are extremely expensive, mostly because voice and data services must be supported on different wires. Therefore, each service needs separate hardware to accommodate the voice and data types of traffic. Needless to say, your local phone company then passes the costs of building and maintaining a circuit-switched network to the you, the consumer. Unforturnately, this equals higher rates for your telephone services.
VoIP – How Does it Work?
VoIP technology is when phone calls travel networks using Internet Protocol (IP). What this means is that the calls are passed through the Internet or privately managed data networks that are using IP to send the calls from one location to the other. So whether the call is passed through the Internet or data networks, the voice stream is broken down into packets, compressed, and sent toward their final destination by several different routes.
This is where circuit-switch technology and IP technology differ, in that circuit-switched technology uses a ‘permanent’ connection for the entire phone call. Once the call reaches the callee, the voice stream packets are reassembled, decompressed, and switched back into a voice stream by several hardware and software elements, depending on the call’s final destination. The type of software and hardware needed to start and end a phone call is determined by where the call originated, such as a PC, phone, or an Integrated Access Device (IAD) and whether the call is going to be completed on a PC, telephone, or IAD.
ADVANTAGES OF VoIP
The following is a list of the numerous advantages for using VoIP:
· Voice and data can be sent over the same lines.
· 8 time the number of phone calls can be placed on those lines than in the circuit-switched environment.
· Quality of sound is excellent.
· Lower operating costs due to reduced hardware requirements and a more efficient network infrastructure.
· Lower cost structures enable lower rates than the traditional telephone companies.
· Use of different devices to talk to one another.

January 6th, 2010Experience The Pleasure Of Cost-Effective Communication With VOIP Technology
December 7th, 2009
Do you wish to cut down your monthly telephone bill amount?
Telephonic communication is the lifeline of the contemporary world. Be it communicating with near and dear ones or with customers/colleagues, telephones constitute an indispensable part of one’s life.
However, most of us are bothered by the (hefty) telephone bills that we receive at the end of the month (especially when we make long distance calls). This takes away the charm of talking heartily with your friends and relatives…isn’t it?
Don’t you wish that you could talk hours with your loved ones without worrying about the ‘calling meter’ ticking rapidly while you talk?
Well, good news for all of you! The surge of VoIP technology is sweeping the world today in its stride…and this technology is bringing about a revolutionary change in how people communicate with their telephones. VoIP is indeed the wave of the future!
The VoIP technology enables transformation of the voice data into digital data. Digital data is smaller as compared to a standard electric unit. As a result, the VoIP users can save on valuable bandwidth.
What all do you need to set up VoIP telephony system in your residence/business set-up?
You need high-speed Internet connection to avail the benefits of VoIP. The digital data (after the voice signal has been transformed) is transmitted over the broadband Internet connection.
VoIP phones are exclusively designed for VoIP. You may also go for videophones (supporting VoIP)that will display images while you speak.
Want to use your existing phone(s) for making VoIP calls?
Well, you can use your existing telephone to avail the benefits of VoIP. You need to use a VoIP phone adapter for this.
You may also need to purchase a router. Usually, the VoIP service providers provide the hardware that you need to set up VoIP telephony system.
So, do not let the thought of ‘huge’ telephone bills deter you from talking to your loved ones heartily. Enjoy the benefits of VoIP telephony and experience the pleasure of communicating in a cost-effective manner!

VoIP Tutorial – Understanding VoIP
October 20th, 2009
VoIP is fast becoming the replacement technology for voice communication. However many people still have questions as to how it works? VoIP costs less than your traditional phone service, this is what makes it attractive to most consumers. Not only does it cost less than your traditional phone service it also costs less than the vast majority of monthly cell phone plans.
The number of VoIP providers is increasing giving you more choices and better calling plans. VoIP is still at its developmental stage. The VoIP service is available for both commercial and residential use, ranging from PC-to-PC service, all the way up to phone-to-phone. The following are the basic features of VoIP.
Anybody with an internet connection has the basic capability to use a VoIP service and benefit from the cost savings associated with VoIP. A basic plan that offers a number of long-distance minutes is very inexpensive and if that’s what you need then VoIP will work perfectly for you.
VOIP is a method which takes voice phone calls and then encodes them digitally. Basically VoIP is the protocol that is used to send your voice over the internet. The VoIP technology transmits your voice over what is called an IP network.
Most everyone agrees that VoIP is the future of voice and data communications.. By the looks of it VoIP is going to continue to grow and expand. VoIP is the Wave of the Future–”and the Present. Although you may be intimidated by this new technology at present, my advice would be to learn more about this new service as it seems this technology is here to stay.
