You are wrong (sorry).

All that means is that the bridging has switched to a native RTP
bridge. That bridge comes in two variants: a local packet to packet
bridge (where the media flows through Asterisk but is not decoded -
RTP is merely swapped between ports) and a remote bridge. The remote
bridge is where the two channels are in a bridge in Asterisk, but
media flows directly between the endpoints.

If your endpoints are behind a NAT, then no, you cannot use a remote
bridge. No amount of hoping or tinkering will make it so.
