IP Telephony Definitions

• IP is an acronym for Internet Protocol. It is a
  communications Protocol developed to support a
  packet switched network.
• IP Telephony is the exchange of information
  primarily in the form of speech that utilises a
  mechanism known as Internet Protocol.
• Internet Telephony the combination of the term
   Internet  with the term  telephony  is seen
  as inappropriate. The Internet offers many
  capabilities to users including the ability to
  carry bi-directional speech in real time or near
  real time. This is considered to be an intrinsic
  capability of the Internet and not a
  telecommunications service.
