The Chat area on the Conference screen contains a list of messages exchanged by conference participants. The Chat area also has a field where you can type messages.
You can view the participant name and time stamp with each message. You can send public messages to all participants in a conference or private messages to an individual participant.
Note:
Guest users do not have a Conferencing profile and cannot send or receive messages in a public chat.
If your administrator disables the chat capability on the server, you cannot view the chat option when you join a conference as a moderator or participant.
