OVERVIEW OF VOIP :
You have probably heard of the word "VoIP" even if you do not understand the reason for all this excitement. VoIP stands for "Voice over Internet Protocol" and will change the way you think about making long-distance phone calls. Basically, VoIP technology transforms analog audio signals (that is, the sounds you hear when you speak on the normal phone) into a digital signal (which is then transmitted over the Internet). So, why is VoIP revolutionizing the industry? Because that means that by getting some of the free software available at that time, you can totally ignore your phone company and start making long-distance calls for free! This revolutionary technology has the ability to completely change the phone system worldwide! You may have seen TV commercials for one of the pioneers of VoIP. One of the interesting elements of VoIP is that there is no single way to make a VoIP call. In fact, there are three ways to make a VoIP call: 1) VoIP through ATA: this is the most used VoIP method today. Using the analog telephone adapter (ATA), connect your regular phone to your computer or an Internet connection. ATA is an analog-to-digital converter that takes your phone's analog signal, converts it to digital data, and transmits it over the Internet so you can make VoIP calls. That's how AT & T Vonage and CallVantage handle calls. VoIP ATA is free with its services and making use of VOIP and ATA is simple and easy for everyone. Open the box, connect the phone cable to the ATA instead of the power outlet and you will be ready to start making VoIP calls. Depending on your computer, your place of residence and your type of Internet connection, you may need to install it. VoIP software on the computer, but it should not be too difficult for most people. 2) VoIP via IP Phones: VoIP phones look like a standard phone. They have a phone, cradles and buttons while a VOIP phone makes use of RJ-45 Ethernet connector instead of the standard RJ-11 phone connectors. VoIP phones connect directly to your router and all hardware and software are already integrated to handle your VoIP calls. Look for available Wi-Fi IP phones in the near future, allowing you to make VoIP calls from any Wi-Fi hotspot. This will allow you to take your VoIP phone when you travel and stop and in all cybercafés, hotels or other places where you can use your Wi-Fi laptop and VoIP technology to call anywhere across the globe. 3) Computer-to-computer VoIP: This is without a doubt the easiest way to use VoIP. Long-distance calls are free and many companies offer free or low-cost software for you to use VoIP technology. You need software, a microphone, speakers, a sound card, a broadband or cable Internet connection, and you can start using VoIP immediately. Aside from the standard monthly ISP rate, computer-to-computer VoIP calls are free, regardless of their distance. VoIP telephony is the wave of the future. VoIP technology makes sense in terms of return on investment, economy and infrastructure. This may take some time, but all current networks with circuit switching used will eventually be replaced by VoIP technology with packet switching. More and more companies are already installing VoIP systems and, as VoIP technology touches everyday language, in our lives and at home, it will continue to grow in popularity. The two main advantages of IP telephony for home users are price and flexibility. Today, most VoIP service providers offer similar calling plans to mobile phone companies, commonly known as "per minute rates" for only $ 30 per month. And, like for cell phone plans, you can also get unlimited plans for about $ 79 a month. With the elimination of long-distance charges, unregulated rates, and all VoIP-related gifts, this can save you a lot of money. For example, you may be paying more for features like: • Call waiting • Call forwarding • Caller ID • Repeat dial • Return of the last call with VoIP These services are standard. In addition, some advanced features make VoIP interesting. With some VoIP providers, you can configure call detection options and, in fact, have some control over how calls from certain numbers are handled. For example, you can: • Divert calls to a specific number • Send a call directly to voicemail • give the caller a busy signal • Play a "Not in use" message on most VoIP services. You can also check your voicemail on the Internet or attach messages to an email sent directly to your computer or mobile device. (By the way, if you're interested in any of these features, if all VoIP companies are not the same, make some purchases first because prices and VoIP services vary.) The second benefit that makes VoIP so attractive to individuals and small businesses is flexibility. With VoIP, the call can be made to anywhere you can get broadband connectivity. Since VoIP or ATA phones transmit information over the Internet, any provider can manage it. For business travelers, this means they can carry their VoIP or ATA phone on the go and never miss a call.
