Conferencing over IP
CoIP

    (CoIP) Standards for the transmission
   of multimedia over the Internet.  CoIP extends VoIP (voice
   over Internet Protocol) with text, images, video.  The main
   CoIP standard is based on H.323.

   The VoIP forum of the IMTC merged with the H.323 Activity
   Group in January 1999 to form the Conferencing over IP (CoIP)
   Activity Group.

   VoIP uses "VoIP Devices" as gateways to route voice data
   packets over the Internet or PSTN.  Protocols such as SGCP
   and its successor MGCP extend VoIP to handle media other than
   voice data.
