ITU-T H.460.21 (05/2006)

عربي | 中文 | English | Español | Français | Русский
Message broadcast for H.323 systems
This Recommendation defines a feature wherein H.323 devices may broadcast (using multicast) a message to one or more remote H.323 terminals, such as providing an "intercom" function for enterprise telephones, a "paging" service through an enterprise, or a notification system to geographically dispersed terminals. Since the method utilizes standard Internet multicast procedures, the feature may be used on a wide scale to reach any number of H.323 endpoints in a geographic region or even the entire world.
