Both. I am designing for both scenario. I am an ardent advocate of maximizing flexibility "where reasonable". There are extenuating use cases in both directions (and other directions too!) In several years, who knows -- ringing could be added as a separate XEP for enhanced RTT mode (which may include HTML and last message editing, etc.) depending on how the real world usage evolves. Priority is keeping it as simple as a chat state, AND deliverable if message body is deliverable (which means even in private mode). A whole implementation can just follow "Basic Real Time Text" (without key intervals) and ignore 90 percent of the document. The protocol section is only a quarter the size of the rest of document (for good reason) Mark Rejhon
