Audio Conferencing

Many say that the Voice over Internet Protocol or VoIP is one of the greatest innovations in human communication. That strong statement may lead one to ask why is it so? How is VoIP different from the invention of the telephone, which is impossible with the slow break inefficient long-distance communication? Well, to understand, one must understand how VoIP works.

How does VoIP work?

As the name implies, VoIP is the transmission of speechInternet. The secret of its success lies in its ability to send voice packets from VoIP. As Vint Cerf, commonly known as the father of the Internet, this can be considered as parcels by post card. Each card contains limited information needed to use the card for the full report, a piece of the puzzle to give. Once we receive and collect the cards can reveal the entire message, as opposed to a long letter.

Before this can happen moresteps must take place.

First try using the audio on your computer. Sampling is a process that detects and stores a small amount of sound. In all VoIP, IP network is instead stored in the computer, spare sound is transmitted throughout the country. Overall, bits of audio to convert back to what type is compatible with the reception equipment is a computer or telephone, so that the recipient may be able to listen to the full andoverview.

But before the sound is sent to the other side of the line, must be compressed to be able to travel more easily through the Internet. Compressing the audio will be less space is needed, so it can quickly be sent over IP network. The main process by compressing audio codec (compressor / decompressor). Many available codecs for VoIP, as well as other media like video or photographs. In essence, the codecreduce the bandwidth of these files for easier navigation. When the bit audio is compressed, will be larger the pieces together and form data is put into packages ready to ship. A standard IP packet contains approximately 10 milliseconds worth of sound.

The last step for VoIP to work, then the other side of the communication to the parties. When sending IP packets, the receiving end must be able to read the digital sound bites, otherwise usingVoIP would be useless.

There are two ways to facilitate this. Depends on receipt of the users, since IP packets are received through analog technologies (telephone, cellular, etc.) or digital (including online). There is no problem if they receive digital because you can then read automatically. Here's how Skype works.

But analog technology used must have a digital converterdata into an analog signal of the device is read.
