Is it possible to override the chat window functionality without creating a visualforce page?
I want to override a system message when there are no agents to say something like "Call us at this number xxx-xxx-xxxx" instead of "Your chat request has been canceled because no agents are available."
Is there a predefined live agent visualforce page that I can add the following code to? Or will I need to create a new visual force page?
<liveAgent:clientChatAlertMessage agentsUnavailableLabel="Call us at this number xxx-xxx-xxxx" />
