The illustration on the right explains how Ipertel's VoIP system works.

As you can see, on the left-hand-side we have the client (the physical residence of the caller is irrelevant for a well-functioning system; the caller can reside either within Italy or abroad, the minimum requirement is an Intenet connection with at least a 12 Kbit/s bandwith). On the right-hand-side of the illustration we have the Ipertel Server and below, on the right, we can see the receiver of the call.

We can summarize a VoIP call with just a few simple steps:

• The caller dials the number he/she wishes to call and the VoIP device (in this case a Mediatrix 1102) connected to the telephone transforms the call from traditional telephone signals to VoIP signals.

• The VoIP device is connected to the LAN which in turn is connected to the Internet via an ADSL or similar type connection. The call is sent over the Internet to our Server, which upon recognition of the number being called, directs the traffic to the desired destination.

• Upon arrival at the desired destination (or more simply put the"closest possible") the "Internet" call is sent to a public telephone network through a switchboard that converts the call from VoIP signals to traditional telephone signals and sends it off to the desired receiver.

VoIP technology allows the user to continue to utilize a traditional telephone handset, just as if he or she were connected to a traditional phone line.
