Hello,

the error message is what you printed from config and $du was not set.

If you want to troubleshoot better, set debug=3 in kamailio.cfg and watch the log messages -- there will be plenty of them and you should get a better idea of what happens there.

Cheers,
Daniel

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>
