Don't know if rtpproxy can do this, rptengine should be able to.

If you look at your config, all calls to rtp_* are conditional. If you
want to always call the rtp_* function, just remove the conditions. eg

# RTPProxy control
route[RTPPROXY] {
#!ifdef WITH_NAT
       if (is_method("BYE")) {
               #unforce_rtp_proxy();
               force_rtp_proxy();
       } else if (is_method("INVITE")){
               force_rtp_proxy();
       }
       if (!has_totag()) add_rr_param(";nat=yes");
#!endif
       return;
}

becomes

route[RTPPROXY] {
       if (is_method("BYE")) {
               #unforce_rtp_proxy();
               force_rtp_proxy();
       } else if (is_method("INVITE")){
               force_rtp_proxy();
       }
       return;
}

You already added an unconditional call to route(RTPPROXY).
