[SR-Users] NATMANAGE quirks

[aft]

Hi,

I'm trying to re packet rtp streams based on Destination IP. I've
implemented it like below :

route[NATMANAGE] {
#!ifdef WITH_NAT
        if (is_request()) {
                if(has_totag()) {
                        if(check_route_param("nat=yes")) {
                                setbflag(FLB_NATB);
                        }
                }
        }
        if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB)))
                return;
        if (is_request()) {
                if (!has_totag()) {
                        add_rr_param(";nat=yes");
                }
                xlog("Destination [$du]...");
                if ($du == "108.59.14.153")
                        rtpproxy_manage("coz20");
                else
                        rtpproxy_manage("coz100");
        }
        if (is_reply()) {
                if(isbflagset(FLB_NATB)) {

                        fix_nated_contact();
                }
                rtpproxy_manage("coz100");
        }
#!endif
        return;
}

But its not working, and the log comes up like :

Oct 21 08:12:33 srv4617 /usr/local/sbin/kamailio[28346]: ERROR: <script>:
Destination...... <null>
