Which ITU videoconferencing standard is designed to interoperate via IP?

Interoperability over IP in ITU videoconferencing is achieved by the H.323 signaling and control suite. It defines how devices locate each other, establish calls, negotiate capabilities, and carry media across packet-switched networks, so equipment from different vendors can work together on IP. The other options relate to either ISDN-based systems (H.320) or codecs for video compression (H.261 and H.264) rather than the IP interop framework itself.
