Switching Between Chat Sessions
By default, all open chat sessions are automatically put on hold except for the chat session that is currently active. When an agent moves away from the currently active chat session by clicking another chat tab, the previously active chat is automatically placed on hold and the previously suspended chat is resumed.
Where all chat sessions are on hold and an agent manually accepts a new incoming chat, then that new chat becomes the active chat session and all other chat sessions remain on hold.
To switch between chat sessions
In the chat pane, click the chat tab belonging to the chat session that you want to move to.
Resume work on the active chat session.
