The contact is fixed for INVITE. Also, replies are routed according to
the Via-Header, so this isn't the issue.

What I've found out in the meanwhile is, that it's the use_media_proxy()
in the reply-route which causes the problem. If I comment this line, the
200-OK is routed without problems (but there's one-way-audio,
obviously). Any hints in that direction?

Andreas
