Hello;

Results are here. Once i tried carrierroute config with kamailio V4.1.9 and it works. here version is kamailio 5.0.0-dev10 . it is started with "kamailio -dd -E"

[root@Test  master]# kamcmd cr.reload_routes
[root@Test  master]# kamcmd cr.dump_routes
error: 500 - Internal error - carrier structure
[root@Test  master]#
[root@Test  master]#
[root@Test  master]# kamctl rpc cr.dump_routes
{"jsonrpc":"2.0","result":{"routes":[{"carrier":,"id":1,"domains":[{"domain":,"id":1,"data":["      NULL: 100.000 %, 'ip:5060': ON, '0', '', '', '338'"]}]}]},"id":9684}

here is log

In addition , I tried to modify code like this  and it didnt work either. it gives same error.

                    if(rpc->struct_add(dh, "Sd[", "carrier", "at",
                                                "id", "123",
                                                "domains",  &eh)<0) {
                                LM_ERR("add carrier structure failure at count %d\n", i);
                                rpc->fault(ctx, 500, "Internal error - carrier structure");
                                goto error;
                        }

kamctl rpc cr.dump_routes
