Hi

I have a kamailio proxy in front of asterisk ver 13 servers. I’m using path support to route to the relevant asterisk server depending on the domain in the sip header. The incoming registers & invites from sip endpoints get routed to the correct asterisk server , but when asterisk is sending  sip options to the end points  my kamailio config is not routing the option on to the endpoint .

Kamailio debug shows error below

ERROR: <script>: 192.168.200.131 OPTIONS sip:1333@192.168.200.112:5062 -- domain "192.168.200.112" is not found in domain table 192.168.200.131

Am I correct in thinking that this SIP option should be getting routed via my on-reply route.

the sip option looks like it is failing here at the start of my config

if (src_ip != BACKEND_NET4)

        {

                xlog("L_NOTICE", "FROM CLIENT IP: $si $rm $ru  $td \n");

            # SIP request packet client->backend

            if( !loose_route() )

            {

                if (!lookup_domain("$td", "dattr_")) {

                    xlog("L_NOTOCE" , "Domain lookup, $rm ");

                    xlog("L_ERR", "$si $rm $ru -- domain \"$td\" is not " +

                        "found in domain table $si\n");

                    drop();

                }
