How does it work?

VoIP is making use of your internet connection in order to traffic your voice calls. Simply put, your voice is converted into DATA packets. These DATA packets are then transprorted over the internet to its destination. Once it has arrived at the destination these DATA packets are then converted back into an audio file and heard by the callee on the other side.


Where traditional PSTN or GSM providers are involved, calls are trafficked over the internet to a point and  then originated and terminated on that network.
