‘If you would understand anything, observe its beginning and its development’. Aristotle

Since its inception, IMTC served as an industry convergence point for Voice, Data, and Video over IP. As the rich-media communications concept evolved from traditional switched networks solutions to IP networks, ITMC was there to set industry standards.


  • 1993: The Consortium for Audiographics Telecommunications Standards, Inc. (CATS) was established.Its focus was on the T.120 standards suite for multipoint data conferencing. Multimedia Communications Community of Interest (MCCOI) was established. Its primary focus was on the ITU-T H.320 (ISDN) and H.324 (POTS) standards suites for multipoint video communications.

  • 2011: IMTC addresses rich-media deployment obstacles and interoperability in enterprise and wide area networks.
  • 2013:IMTC celebrated its 20th Anniversary in Porto, Portugal
