What is H.323 protocol stack?
TOP The H.323 protocol stack is an umbrella recommendation from the International Telecommunications Union (ITU) that set the standards for multimedia communications over packet-switched networks such as Internet and Intranet. These standards define how components that are built in compliance with H.323 set up calls, exchange compressed audio and video, participate in multi-unit conferences, and operate with non-H.323 endpoints.The H.323 protocol stack’s functions include: ” Defines how audio and videoconferencing systems communicate over packet-switched networks that do not guarantee QoS, such as Internet and Intranet. ” Addresses call control and management for both point-to-point and multi-point conferences. ” Addresses QoS issues with a centralized gatekeeper component that let administrators manage media traffic, bandwidth, and user participation.
