title: Send sms throw smpp protocol error
body: <p>I need to send SMS via smpp protocol.</p>
  
  <p>I’m sending an MT message from an emse server to an esme client </p>
  
  <p>My question is about  the SMPP traffic and this error "vendor specific error" ... if it's due to a malformed packet smpp or I must refer to my SMPP provider? any explanation please ?</p>
  
  <p>I attached a dump traffic on Wireshark for more details.<a href="https://groups.google.com/forum/#!topic/restcomm/5YwvKVtkloY" rel="nofollow noreferrer">link to pcap file</a></p>
