The economy in telephonic linkings was more easy and expressiva. The VoIP, or voice on IP, is the technology that becomes possible to establish telephonic conversations in a net IP, becoming the transmission of voice plus one of the services supported for the net of data. They is esteem that the economy in companies who had adopted the new technology turns around 20% 50% of the cost of the service of conventional telephony.

Another great advantage of the VoIP in relation to the conventional telephony is that this last one is based on commutation of circuits, that can or not be used, while the VoIP uses commutation for packages, what it more becomes it “intelligent” in the exploitation of the existing resources, the physical circuits and width of band.

This characteristic, commutation for packages, also bring another advantage to the VoIP, that is the capacity of the voice packages “to search” optimum way between colon, having always more than a way, or route, available e, therefore, with bigger options of contingency.
