Bandwidth increasing globally, and the optimization of layer 2 and 3 teams to guarantee the QoS (Quality of Service) voice in real time makes the future of voice over IP very promising at the global level, and not only, will not stop its expansion process, but it will grow in number of users and providers. In the United States, some VoIP service providers, such as Vonage for example managed to attract a significant market share. In Spain, thanks to the flat rate voice, conventional operators managed to avoid the massive landing technology operators for voice over IP. However, the most important expansion of this technology, is headed by certain developers of systems such as Cisco and Avaya, that have managed to integrate into its offerings, data and voice networks. Other manufacturers such as Alcatel-Lucent, Nortel Networks, Matra, Samsung and LG also develop corporate solutions for voice over IP in their telecommunications equipment, not to be left out of the trend which already marked the market.

Technology Voice over IP is not a service as such, but a technology that uses the Internet Protocol (IP) through which are compressed and decompressed packets of data or datagrams, highly efficiently to allow the communication of two or more clients via a network such as the Internet network, which allows to offer telephony or videoconferencing services, among others.

In its technological aspects, there are three elements necessary to exploit: terminals: substitutes of current phones. They can be deployed both in software and hardware. Gatekeepers: Are the focus of organization-wide voice over IP, substitutes for existing plants. It is usually a software. All communications would go through her. Gateways: It is the link with the traditional telephone network, acting transparently to the user. With these three units, the voice over IP network structure has no territorial limits, you can connect to two cells of the same company or two companies in any part of the globe, and with all communications completely free. Thus, the only limit is that companies impose to not make the leap to IP.
