Voice over IP
VoIP

   <communications> (VoIP) Any technology providing {voice
   telephony} services over {IP}, including {CODECs}, {streaming}
   {protocols} and {session control}.  The major advantage of
   VoIP is lower cost, by avoiding dedicated voice circuits.

   Currently VoIP is being deployed on internal corporate
   networks, and, via the {Internet}, for low cost (and low
   quality) international calls.  It is also used for telephony
   applications such as voice and fax mail.

   The {ITU} standard is {H.323}, which is a whole suite of
   protocols, while the {IETF} has developed the much simpler
   {SIP} to solve the session control problem and {MGCP}/{Megaco}
   to solve the gateway problem.
