Hi, this may make your config a little more tricky: You could instruct the RTPProxy/Mediaproxy-ng to "Trust" the IP in the SDP for the Originating call to PSTN and the Freeswitch (add "r" the flags). Have you verified/checked, that rtpproxy_manage() is really called for both the 183 and the 200 OK?
