Sending Text Messages During a Conference Using Message Overlay
The Message Overlay option in the Conference Profile allows the operator or administrator to send text
messages to a single participant, a number of selected participants or all participants during an ongoing
conference.
The number of characters that can be included in a message varies according to the language and can differ
due to the type of font used. For example, the available number of characters in Chinese is 50 (32 for
Collaboration Server 1800) for English and 50 (48 for Collaboration Server 1800) and for Russian.
The message can be set to be displayed at various positions on the screen in different colors, static or
scrolling.
