The message says it, and your SIP message proves it: the SIP message has no
body.
nathelper operates on the SDP body, it mangles them (together with rtpproxy)
so that the SDP body sent to the receiver contains the address of your
machine running OpenSER instead of the real phone. This is so that the
machine can act as RTP proxy on network edges.
Since your SIP message has no SDP body there is nothing nathelper can do :-)
