Following code shows how you can return non-OK status to client.

Code: Select all

_server.evClientBind += server_evClientBind;

private void server_evClientBind(object sender, Inetlab.SMPP.Common.SmppServerClient client, Inetlab.SMPP.PDU.Bind data)
{

   data.Response.ChangeSystemId("My SMPP Server");

  //Check SMPP access, and if it is wrong retund Bind Failed.
   if (data.SystemId == "")
   {
         data.Response.Status = CommandStatus.ESME_RINVSYSID; 
         return;
   }
   if (data.Password == "")
   {
        data.Response.Status = CommandStatus.ESME_RINVPASWD; 
        return;
   }
}

Also you can use another statuses such as ESME_RALYBND, ESME_RBINDFAIL
