Voice Over Internet Protocol

Using Internet to make phone calls
In today's home and business life, we need to communicate with many people who are far away. Using a regular telephone will get us a huge bill with the long distance charges. Even a cell phone can be inadequate for all the long distance needs. The cell phone can cut you off or go to roaming. This can make phone calls expensive and frustrating for both parties on the line.
There are different ways to make phone calls or have live conversations with someone on the Internet. There are web sites that are set up like a regular phone service with all the same amenities. These phones services can come with a charge depending on the features and usage. They can have things like call waiting, three way calling, and voice mail.
This is a good option for people who need to do a large part of their business on the phone and want a reliable and inexpensive way to do it.
There are programs and hardware that can add to the computer to turn it into a phone. There is telephony software that will give access to the phone system. There is a need to have a microphone and speakers or a headset before making calls. There are wireless headsets available.
Live conversations can be possible through the use of web based messenger services. There are many web servers like MSN and Yahoo that have a messenger service that can be downloaded onto the computer. They allow sending instant messages, picture, and files. They can also allow turning the PC into a video phone with the use of a web camera. All we have to do is contact the person we want to speak with, and then invite them to view the camera. After that is set, there is a button that allows us to speak to them directly. Then viola, is a videophone. In the coming years, voice over internet protocol (VOIP) is going to dominate the communication world with its technological advantages. In fact, many communication companies have started using VOIP technology for their long distance calls. People may have used this service unknowingly since many companies use VOIP to route long distance calls.
Definition
Voice over Internet Protocol (VoIP) is a technology which allows making telephone calls using a broadband Internet connection instead of a regular phone line. Basically, individuals can now use their broadband Internet connections to place phone calls rather than using their traditional phone lines. Ideally, the sound quality is the same as that of a standard telephone line and therefore the people on the other end of the phone call will never know the difference.
The technology, though complex, is quite direct. The VoIP provider takes the regular, analog voice conversations and converts them into data that can then be sent across the Internet using a high-speed broadband connection. At the other end of the call, the data is converted back into an analog signal that the conventional telephone system can deliver to the person whose number was initially dialed. All of this is accomplished seamlessly while using normal telephones at both ends. In other words, people have to speak through their microphone in order to get the most out of VoIP services.
What makes it so effective is that it turns speech into digital data that can be stored, browsed, copied, combined with other data, and distributed to any device that connects to the Internet. VOIP has a few features that provide different technical modes such as Caller ID, Call Waiting, Call Transfer, Repeat Dialing and Return Call. These features enable you to give the caller a busy signal, send the call directly to voicemail, and forward the call to a particular number. Soft phone is another distinguishing feature of VOIP service. It is specially developed software that installs the VOIP service into your computer.

How VoIP Is Used
While there are a number of ways that VoIP is currently being used, most individual callers fall into one of three categories: ATA, IP Phones, and Computer-to-Computer.
ATA or Analog Telephone Adaptor, is the most common way of using VoIP. This adaptor actually allows to hook up the phone to the computer, and then to Internet connection. What the ATA does, is turn the analog signals that phone sends out into digital signals that can be sent over the Internet. Setting up this system is quite simple. It simply requires ordering an ATA ( an adaptor), plugging the cable from the phone which would normally go into the wall socket into the ATA, and then the ATA gets plugged into the computer, which is connected to the internet. Some ATAs include software that has to be installed on the computer before its ready, but basically it's quite a simple process.
The next type of VoIP usage utilizes IP Phones instead of the home phone. The IP Phone looks just like a normal phone, with all the same buttons and cradle, the only difference is that instead of having a normal wall jack connector, it has an Ethernet connector. This means, that instead of plugging in the IP phone to the wall jack like we would with a regular analog phone, it gets plugged directly into the router.
This option allows to circumvent the personal computer, and it also means that will not have to install any software, because all built in to the handset.
The simplest and cheapest way to use VoIP is through computer-to-computer calls. These calls are entirely free, meaning no calling plan whatsoever. The only thing that needs, is the software which can be found for free on the internet, a good internet connection, a microphone, speakers, and a sound card. Except for the monthly internet service fee, there is literally no cost for making these calls, no matter how many calls make.
For large companies, VoIP also offers some very unique possibilities. Some larger companies are already utilizing the technology by conducting all intra-office calls through a VoIP network. Because the quality of sound is comparable to and in some cases surpasses that of analog service, some international companies are using VoIP to route international calls through the branch of their company nearest the call's destination and then completing it on an analog system. This allows them to pay local rates internationally and still utilize the same intra-office VoIP network that they would if they were calling someone in the next cubicle over.





Advantages in using VoIP
There are many advantages to switching over to a VoIP service, but the biggest one is cost. For the most part, long-distance and international calls will be significantly less expensive for individuals using a VoIP service rather than a traditional long-distance or international plan. Most VoIP service providers also offer a number of additional free features already established with traditional phone plans, such as Call Waiting, Caller ID, Voicemail and more.
There are other advantages as well. For example, because of the convergence between the VoIP phone service and the Internet, some providers will even allow users to receive Voicemail messages as email attachments. Also, if there is a cable broadband connection, it will be possible to keep current telephone number as well.
Signing up for a VoIP plan is actually quite simple. Really, all that needs is a broadband Ethernet connection such as DSL or cable, any touch-tone phone (corded or cordless) and a credit or debit card with a U.S. billing and shipping address. VoIP provider will supply with the proper phone adapter upon signing up, usually at no additional cost. As for the person on the other end of the call, all they need is a regular phone. They need to use a VoIP service or even have an Internet connection for the call to go through.
Lastly, although VoIP calls are placed through the Internet connection, they will not affect the ability to use the computer. Thus, it will be possible to continue to surf the web and send emails while being on the phone. Also, because VoIP utilizes the Internet connection and not the computer, the computer does not even need to be turned on in order to place a call.
