“ What is VoIP “ is a question that not many can answer nowadays even if many use it in lots of domains, they don’t know it.
IP telephony also known as VoIP ( Voice over IP ) is a technology that has already begun to change the way communication is done between people. One of the main benefits of this technology is the decrease in classic telephony costs.
The technology ” Voice Over Internet Protocol “, briefly called VoIP, refers to the possibility of making calls between two correspondents, of whom at least one must have an Internet connection ( dedicated or temporary ) and because the Internet global network shares technology and does not use traditional switched technology, as with traditional telephone services, the call cost is much lower.

The person who initiates ( the caller ) the call may be located anywhere in the world and can call any country in the world at two clicks away. The call can be done with a computer connected to the Internet or many types of VoIP hardware devices. In this case, the caller uses a computer or telephone connected to a voice conversion device / IP, and the called party answers a regular phone. The voice signal through most of the way is used in IP packets by respecting the H.323 standard format in Internet. The signal is then reconverted to voice signals and introduced via a telephone network equipment ” gateway ” or a ” Telephone Switch “. VoIP hardware devices are similar to regular phones with the difference that they make conversion from voice into IP packets and vice – versa. They can connect to the Internet and make international phone calls without a computer.

The price of calls through the Internet is several times lower than the price of traditional calls. At the two ends of a VoIP connection, as stated before, can be computers, phones, VoIP hardware or faxes in any combination and in order to connect to the voice network called generically VoIP Net, Vip Net equipment is used to convert voice from either a regular phone or from a telephone in IP packets. The equipment proposed to the Vip Net client used to connect to the VoIP Net network type are manufactured mainly by Cisco, and there are many types that offer the best performance / price ratio. Nowadays there are many options and VoIP is the future of telecommunications in terms of voice and possibly faxes.
