What is VOIP?

Voice over Internet Protocol(VoIP) is a protocol optimized for the transmission of voice through the Internet. VoIP is also known as IP Telephony, Internet telephony, Broadband telephony, Broadband Phone and Voice over Broadband. Companies providing VoIP service are commonly referred to as providers. Some cost savings are due to utilizing a single network to carry voice and data. VoIP to VoIP phone calls are sometimes free, while VoIP to public phone networks may have a cost that is borne by the VoIP user.


VOIP Services

VOIP often has a large set of functionality that is free (whereas the normal public phone system must charge for each of these functions to allow for the added cost they must go through in order to provide the functions):
  • extra telephone line
  • 3-way calling
  • call forwarding
  • automatic redial
  • caller ID; features that traditional telecommunication companies (telcos) normally charge extra for.
  • secure calls
  • can be used from anywhere you have an internet connection (location independence)
  • integration with video, data, audio conferencing, managing address books, and others
