Thanks for the detailed logs: First off I don't think reconnecting the conference port will do much here. I think the problem is here: Session-Expires: 120;refresher=uas Min-SE: 120 I would look for why that happens and see what I could make of that. Might also try going to version 1.4 and see if the problem exist there. Sorry couldn't be of more help.
