What is VOIP?

VOIP stands for Voice Over Internet Protocol. It is nothing but a simple technology that allows users to make phone using the Internet connection rather using the traditional landline or analog phone line. Today, VOIP is becoming more popular and replacing the analog phone lines. Using VOIP it is possible to call users having mobile phones as well as landline phones.

VOIP also has a caller ID like the traditional phone. In VOIP the voice messages or calls are converted into small packets of data and sent through the Internet Protocol (IP) network. To use VOIP, the broadband internet connection should have a minimum bandwidth of at least 90 kbps. The clarity of the VOIP calls will be more if the bandwidth of the internet connection is more.

In short, Higher speed = Better quality. Apart from bandwidth, consistency or coverage of the internet network also plays an important role to improve the quality of VOIP calls.
