[kamailio/kamailio] KSR.dispatcher.ds_is_from_list is returning always true (Issue #3988) - sr-dev

1 Oct 2024

### Description
I'm trying to check if the incoming message is from the dispatcher hosts using KEMI
function ds_is_from_list from a lua script:

```
if KSR.dispatcher.ds_is_from_list("-1", "2") then
  KSR.info("Dispatcher List \n");
  return "list"
end
```

I'm getting always true if when the source IP of the request is from a different
network:
```
/usr/local/sbin/kamcmd dispatcher.list
{
        NRSETS: 1
        RECORDS: {
                SET: {
                        ID: 1
                        TARGETS: {
                                DEST: {
                                        URI: sip:127.0.0.1:5060
                                        FLAGS: AX

                                                STD: 0
                                                EST: 0
                                                MAX: 0
                                                TIMEOUT: 0
                                        }
                                }
                        }
                }
        }
}
```

Works ok when I'm using this function from the default configuration file:
```
if (ds_is_from_list("-1", "2")) {
     xlogl("L_INFO","Dispatcher List\n");
     exit;
 }
```
