The gateways are not used only for the connection of two or more devices, but to manage the transfer of the different types of data: for example, there is a computer in a corporation’s building where one of the employees has to call another employee who works outdoors and has a mobile phone that belongs to the corporations’s communication system:

As the first employee initiates the call, it goes through the server that sends it to the proper destination through a VoIP VLAN network to the VoIP GSM gateway. The gateway converts the VoIP call into a GSM call in order to make the mobile phone able to receive it. (Figure 1)
