http://openser.org/docs/modules/devel/usrloc.html#AEN252

it's mode 3 (only available in CVS head)

I still would use only one proxy and apply NAT traversal only for 
clients which use the "NAT traversal" port on your openser.

The idea is:
...
if ( dst_port = 6060) { # needs NAT traversal
	if (is_method("REGISTER")) {
		setflag(9);
		# this is the natflag specified in userloc module
# http://openser.org/docs/modules/1.0.x/registrar.html#AEN103
		fix_nated_register();
	} else {
		# do all the NAT traversal, activate RTP proxy
	}
}

# now do the normal call and REGISTER handling

...





...
	lookup("location");
	if(isflagset(9)) {
	   ...#force rtp proxy
	}
....
