VoIP, short for Voice over IP is a term that refers to techniques and communication protocols used for Internet telephony. The term is generally associated with all services that are not used by public telephone systems. All information is sent over the Internet.
The public telephony network and the Voice over IP system are two different things. Even if the work basically the same, the way the signal is sent is different. First, the message is encoded and digitized and it's sent in packs to the other end of the line. The receiving end takes the necessary steps to retrieve the message and these are basically the same but in a reversed order.
People usually associate IP Telephony with Voice over IP. These 2 terms are different because they involve different things. VoIP is just a way of transporting information for the IP telephony. This particular difference sets the 2 terms in 2 different categories.
In order to make phone calls, every system needs codecs. Even more, these codecs are associated with a certain application that makes the encoding and decoding of the voice signal. Every application or program uses certain signal recognition software that depends on network and Internet connection.
At first, Voice over IP was used only on computers because they had an Internet connection. In time, technology evolved and nowadays smartphone users are also able to make calls using their phones. That's because more and more phones are like small computers and come with an Internet connection. Networks like 3G and 4G offer users the possibility of sending messages and making video calls.
The development of this service began in 2004. Users that had access to a computer with Internet access were able to make phone calls in the same country and even internationally. The best part was that they didn't have to pay too much for a subscription. For a small fee, they were able to make free phone calls in the same country with unlimited bandwidth. Plus, companies offered free phone calls to certain countries.
There are many differences between standard phone systems and VoIP. For example, the best part of using Voice over IP systems is that a phone number is quickly associated with a country. This goes both ways: when making a call or when receiving a call from someone in a different country. This is only one small advantage. The biggest advantage is the cost. Compared to standard phone systems, Voice over IP is much cheaper. Plus, if 2 users in different countries install the same application they will be able to talk unlimited without cost.
