Introduction and History
What exactly is a VoIP? VoIP stands for "Voice over Internet Protocol." It can be defined as a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet." ("Voice over IP.") VoIP was the successor and child between the telephone and the internet. Long distance calls over analogue networks were very expensive in the past; therefore adding the internet into telecommunications equation was revolutionary. The first real thought of using VoIP was in the 1990s when hobbyists wanted to mess around for ideas to use their PC's to avoid those expensive long distance calls. In the early generations of VoIP it was very specific to pull off; bothcomputer had to have the same software, same sound card, and same microphone. A variety of problems plagued the early generation of VoIP applications such as horrible audio quality and connectivity issues. The biggest breakthrough in the world of VoIP was the adoption of "Switching." Switching is defined as the "process of changing a voice data packet into something that could be read by telephone network and vice versa." (The History of VOIP") This lead to VoIP being more affordable so companies and consumers were able to readily use it more.
To quickly summarize how VoIP's work here is a simple explanation: "To keep things simple, think of VoIP as a sophisticated version of the technology you use to record a voice memo on your computer. When you record a voice on the computer it sends a frequency range and uses simple CODECs to convert analog signals to digital audio. The computer might also compress the voice file so it takes up less space." ("The History of VoIP")
Advantages & Disadvantages
There are many advantages of using VoIP in business or even for consumers, but I will only cover a few of them. First, you can get rid of your landlines. With VoIP there is no real requirement to owning a landline. The price and accessibility of VoIP is superior in almost every way than the conventional landline. For businesses and consumers international calls can be costly, but when using VoIP it can be extremely low in price. For some VoIP's long distance or international calls can be free. For business and employees working from home, VoIP's are helping those workers feel connected to work from their home. Even for remote employees, connecting to work via VPN or VoIP it helps them feel like a part of the business even from the comforts of their own home. For businesses VoIP helps make call monitoring much easier when they can monitor inbound and outbound calls on their VoIP system. Disadvantages looking into the future of VoIP are the increasing hacking of internet services and the unknown integration of 5G technology. ("The History of VOIP")
