Well, I suppose I can't say for sure, but it looks like it's not sending 
anything at all. When I grep a particular Call-ID, the first thing I get is:

Apr 23 15:28:37 sd-rtp01 mediaproxy-ng[7910]: Got valid command from

"Fa1Fe4ZSvBQSF", "command": "answer" }

If my understanding of the control protocol is correct, this is actually 
an answer, not a mislabeled offer, since the offer would contain some 
other attributes.

But maybe not?

I expect an answer because I have an rtpproxy_manage() in an 
onreply_route for 18x/2xx+SDP responses to this INVITE, of course.
