[SR-Users] no event received for call disconnection

[Aleksandar Sosic]

Hi Daniel,

It's done by this cgrates route:
```
# CGRateS request for session disconnect
route[CGR_SESSION_DISCONNECT] {
  json_get_field("$evapi(msg)", "HashEntry", "$var(HashEntry)");
  json_get_field("$evapi(msg)", "HashId", "$var(HashId)");
  json_get_field("$evapi(msg)", "Reason", "$var(Reason)");
  jsonrpc_exec('{"jsonrpc":"2.0","id":1,
"method":"dlg.end_dlg","params":[$(var(HashEntry){s.rm,"}),$(var(HashId){s.rm,"})]}');
}
```

It executes a dlg.end_dlg via jsonrpc.
