The Technology Behind VoIP

Conventionally we have been using our regular analog phones to place calls. The manner in which an analogue phone functions is completely different from a phone facilitating VoIP telephony. To use VoIP, it is essential to have a high speed broadband internet connection.

Once we are ready with a broadband connection, we can place calls in a number of ways. VoIP calls can be placed in three different ways.

• Using an Analog telephone adapter.
• Using an IP phone
• Wireless VoIP
  

However the procedure of placing a call via VoIP remains the same. When a call is placed using the broadband internet, the voice of the caller is converted from analog data to small packets of digital audio data and transferred using broadband lines to the server from where it is transferred to the caller. But before the caller receives the audio data it is converted back to analog form. And the minutes that are consumed in this transfer and receipt are called VoIP minutes.

VoIP technology is relatively much new but still it has gathered enough attention. It sure has the power to completely revolutionarise the manner we make calls.
