Note that it is legal for there to be no media.
So you could accept the call and then reinvite with the media you want
to use. But if you want to reject, I guess 415 is as good as anything. I
like the idea of changing the comment in the response. This won't be
recovered dynamically, but if somebody is trying to diagnose why the
call is failing that will help.

If the invite had SDP with an m-line, then this answer is invalid, so
you are justified in killing the call.
If the invite had no sdp, then the situation is much like your first one
above. So you could accept it, or you can reject it as you show below.
