VoIP (1)

VoIP (voice over internet protocol) is a communication technology in which an individual says goodbye to handsets and wires and make calls through a broadband internet connection. This technology is an analog of phone lines. A person can contact his beloved ones anywhere and anytime. Some VoIP services allow connection between the individuals having the same service. Some advanced VoIP services allow the user to call anyone having a telephone number such as mobile, long-distance, local, and international numbers. While some services work over VoIP phones or computers. Other VoIP services need a telephone connection with a VoIP adapter. This technology is also referred to as

  • Broadband phone service
  • Broadband telephony
  • Internet telephony
  • Internet protocol telephony

Working of VoIP

VoIP changes voice audio into digital codes. These digital codes travel instantly towards the final destination through a private or public internet connection. Digital codes are converted back to voice audio once reached the final destination. A person can make VoIP calls through special VoIP phones, computers, or any other data-driven device. Moreover, wireless hotspots at places such as cafes, parks, and airports allow an internet connection through which an individual can use wireless VoIP service.

Kind of equipment needed

To enjoy VoIP services an individual needs to have a broadband internet connection.The connection is done by DSL or cable modem. Some other types of equipment a user requires are an adapter, computer or specialized phone. If the user is making VoIP calls through a computer, then he needs to have an inexpensive microphone and some software. VoIP phones are directly plugged into a broadband connection and then operate primarily like a conventional telephone. If a user is using a traditional telephone connected with the VoIP adapter, then he can make VoIP calls just by dialing the number as in traditional phones.
