This allows you to make a call directly from your computer, phone or other devices that are connected to the internet. In simple terms, a VoIP call is also called IP telephony, internet telephony, broadband telephony or broadband phone service.

How does VoIP calling works?

So that now we know what VoIP really is, it’s now time to get into the depths and understand how it actually works. In VoIP technology, the audio data is converted into packets of data called as codecs. These codecs are then transferred digitally using the internet connection. At the receiving end, the original audio signal is recovered by decoding these codecs, giving crystal clear voice quality to the user.

CCodecs

Codecs are the most important part of VoIP communication, or you can say codecs are the backbone of VoIP. Codecs help to convert analog voice signals into digital form so that it can be transmitted over the internet. Many codecs work for the smooth functioning of the VoIP call system. G.711 is one of the most important codecs, which samples audio data at 64,000 times per second. In short, codecs help in processing the audio data, which is further compressed in small fragmented packages. These small packages of data are then reassembled once it reaches the receiver’s end.

Packet Switching

VoIP telephony uses packet switching technology, rather than circuit switching used in the traditional phone system. When a telephonic conversation takes place, most of the time it is dead air, which is when neither the sender nor the receiver is speaking. Packet switching eliminates this dead air transmission, thus saving file space and in turn money. In addition to this packet switching also helps to do multitasking over VoIP. Hence you can send files, photos, videos even when your call is on a roll.

  • Easy to install and configure
