People use VoIP for international calls as the costs are significantly lower than regular landline or mobile costs or sometimes even totally free. VoIP works by transmitting analog signals such as voice, fax, SMS and voice-messaging into digital signals which may be sent throughout the internet and not through Public Switched Telephone Network.

HOW DOES VOIP WORK?

To learn how VoIP, works, it's helpful to compare it to how regular phone calls operate.

Circuit switching:

Whenever you use a regular phone to make a call, it really is connected with circuit switching. This is what we call Public Switched Telephone Network generally known as PSTN.

The system works by setting up a channel or circuit between the caller and receiver for the duration of the call.

Within the early days a dedicated copper wire had to connect the two ends in order to make a call. This really is where the aid of an operator service came in, they made sure the wires got connected. This sort of connection was really expensive because you truly owned that piece of wire for the duration of the call, so if you made a call from India to the UK for example, you owned a piece of wire stretching from India to the UK.

These days making calls might be more efficient, as calls are digitized as well as automatic electronic switching has replaced the manual switching. Fiber-optic cables are now used rather than the copper ones and with fiber-optic cables, thousands of voice signals can share the same cable. It means that you do not actually own that wire any more while making a call but you share it with many others.

The way the circuit works has stayed the same throughout the years. For the duration of the call a connection must be made. A standard amount of data - 960 KB gets used per minute that you will be connected, and voice information is sent from both ends. A big part of this data gets lost however because both ends are not sending out voice signals at the exact same time, one may be listening while the other talks and there will be silence at some points as well.

Another disadvantage of circuit switching is the fact that it can only be used by a person at a time. So if you are making a call from a telephone number, that number is now unavailable for use. It only becomes available again as soon as you hang up.

Packet switching:

When you make a VoIP call, it uses packet switching. As opposed to keeping the connection open for the duration of the call as is the case with circuit switching, the connection only opens when there is something to send.
