HOW DOES VOIP WORK?

 

 

To understand how VoIP, works, it's useful to check it to how common phone calls operate.

 

 

Circuit switching:

 

 

If you use an everyday phone to make a call, it is related with circuit switching. This is what we call Public Switched Telephone Network additionally known as PSTN.

 

 

The system works by setting up a channel or circuit between the caller and receiver at some point of the call.

 

 

Within the early days a dedicated copper wire had to connect the two ends with the intention to make a call. This is where the assistance of an operator service came in, they made positive the wires received connected. This type of connection was really costly because you really owned that piece of wire all through the call, so when you made a call from India to the UK for example, you owned a chunk of wire stretching from India to the UK.

 

 

Nowadays making phone calls is more efficient, as calls are digitized and automatic electronic switching has changed the handbook switching. Fiber-optic cables at the moment are used instead of the copper ones and with fiber-optic cables, hundreds of voice signals can share the identical cable. This implies that you don't really own that wire anymore while making a call however you share it with many others.

 

 

The way the circuit works has stayed the same over the years. All through the call a connection have to be made. An ordinary amount of data - 960 KB gets used per minute that you are linked, and voice data is shipped from both ends. A big part of this data gets lost though because both ends will not be sending out voice signals at the same time, one is usually listening while the opposite talks and there's just silence at some points as well.

 

 

Another disadvantage of circuit switching is that it can only be utilized by one individual at a time. So in case you are making a call from a phone number, that number is now unavailable for use. It only turns into available once more when you hold up.
