The error means that there was no response to a register request. That means one or more of:

  • you are sending it to the wrong place;
  • a firewall is blocking it, or the response;
  • you have not configured NAT properly and the recipient is sending the response to the wrong place;
  • you are using NAT, but you do not have it properly configured to pass replies to 5060/UDP to your Asterisk box.
