You should use force_rtp_proxy on the reply too. Also don't use both
 fix_nated_sdp and force_rtp_proxy.

Use something like:
if (nat_uac_test("3")){
    fix_nated_contact();
    force_rtp_proxy();
    t_on_reply("1");
}
/* ... */

onreply_route[1]{
    force_rtp_proxy();
    if (nat_uac_test("1")){
        fix_nated_contact();
    }
}

[this is a very stripped down example, you would want to check the
method a.s.o for a "clean" config ]
