How to connect Discourse to Webex?

We want to connect Discourse to Webex. Do you have any prefferences, ideas in this context?

Should we make the Webex chat read-only? Is that possible? I have just seen the chat integration plugin in Webex and my concern is that people will reply in Webex rather than on Discourse.

Other alternatives include:
Auto-reply to Webex chat saying that the question comes from Discourse and should be answered there
Auto-post from Webex?!? Can the chat intergration plugin work both ways?
