What is VoIP?

Internet Voice, also known as Voice over Internet Protocol (VoIP), is a technology that allows you to make telephone calls using a broadband Internet connection instead of a regular phone line.

Some services using VoIP may only allow you to call other people using the same service, but others may allow you to call anyone who has a telephone number - including local, long distance, mobile, and international phone numbers around the world. Also, while some services only work over your computer or a special VoIP phone, other services allow you to use a traditional phone through an adaptor or gateway.

VoIP allows you to make telephone calls using a computer network, over a data network like the Internet. VoIP converts the voice signal from your telephone into a digital signal that travels over the internet then converts it back at the other end so you can speak to anyone with a regular phone number. When placing a VoIP call using a phone with an adapter, you'll hear a dial tone and dial just as you always have. VoIP may also allow you to make a call directly from a computer using a conventional telephone or a microphone.

VoIP has several advantages over traditional telephony:

  • Wider range of features and facilities. In addition to the basic end-to- end voice conversation, more information and control about each call can easily be provided. This includes sending and receiving messages or data files in parallel with the voice conversation, audio conferencing, managing address books and passing presence information about whether friends/colleague are available online to interested parties.

  • Freer innovation. Innovation progresses at market rates rather than the slow pace of the multilateral International Telecommunications Union (ITU) committee process, resulting in more new advanced features.

  • Lower per-call costs. Once the capital costs of terminals and/or computers and the operating costs of a data network connection are in place, there per call charges versus traditional telecom operators are significantly lower, almost to any destination in the world. A typical VoIP user saves approximately 400% in his monthly bills.

  • Lower infrastructure costs. VoIP reduces the traditional scheme—two separate wiring systems, one for voice and one for network—to a single connection. VoIP is easy to deploy and manage and with BusinessCom Internet via Satellite services now telephone access is available almost in any point of the world!

Although now office environments and homes use a pure VoIP infrastructure, telecommunications providers routinely use IP telephony, often over a dedicated IP network, to connect switching stations, converting voice signals to IP packets and back. The result is a data-abstracted digital network which the provider can easily upgrade and use for multiple purposes.

VoIP is also widely employed by carriers, especially for international telephone calls. It's commonly used to route traffic starting and ending at conventional PSTN (Public Switched Telephone Network) telephones. Many telecommunications companies are looking at the IP Multimedia Subsystem which will merge Internet technologies with the mobile world, using a pure VoIP infrastructure. It will enable them to upgrade their existing systems while embracing Internet technologies such as the web, email, instant messaging, presence and video conferencing. It will also allow existing VoIP systems to interface with the conventional PSTN and mobile phones.
