Hi Ricky,
I think you should  increase the mediaproxy natping interval to 30 and then add use_media_proxy() line after you setflag(6). check below:---
##Detect requests in the dialog behind NAT and flag with 6
if(nat_uac_test("19") || search("^Route:.*;nat=yes")){
append_hf("P-hint: LR|fixcontact,setflag6\r\n");
fix_contact();
setbflag(6);
USE MEDIA PROXY HERE---> use_media_proxy();
};
route(1);
} else {
sl_send_reply("404", "Not here");
}
exit;
}
