How does VoIP work?
VoIP is a packet technology, meaning analogue waves of spoken words are converted to digital signals that travel over the internet then converted back at the other end, so you can speak to anyone with a regular phone number. Calls can be made on the phone, with an adaptor that connects to the internet, or a microphone handset can be plugged into your computer and the number dialled using the keyboard.
The VoIP technology converts the voice signal from your telephone into a digital signal. This digital signal is transferred through the Internet to the other end, and is reconverted into a voice signal for the other end’s telephone user. A VoIP call can be placed using a phone with a special VoIP adapter or directly from a computer using a conventional telephone or microphone.
Voip works just like a regular phone with just one key difference — how the phone call actually gets to your telephone. Instead of using the high priced Telephone Company’s wiring, Voip routes your phone calls directly to your telephone using your high-speed Internet connection. You hear a dial tone and make your phone calls just like you’ve always done. What’s changed is that you don’t pay a big bill to use the phone company’s wires.
VoIP involves the transmission of voice communication using the Internet Protocol that is already common in data transmissions on the Internet. Internet telephony software is also available that enables individuals to use the Internet as a transmission medium for essentially free telephone calls to anywhere in the world.
