I isntall the openser-1.2.2-notls under the centos5.

  I config the INVITE method like this:

   

 

 if (is_method("INVITE"))
 {
  # enable Record-Route
  record_route();

 

  # Is this to one of our numbers
  if (lookup("location"))
  {
   append_hf("P-hint: userloc applied\r\n");
  }
  else
  {
   sl_send_reply("404","Not found");
  }
 }

  route(1);

 

...

 

route[1]
{
 if (isflagset(2))
 {
  if (is_method("INVITE"))
  {
   t_on_reply("1");
   t_on_failure("1");
   use_media_proxy();
  } else if (is_method("BYE|CANCEL")) {
   end_media_session();
  }
 }

 

 # send it out now; use stateful forwarding as it works reliably
 # even for UDP2TCP
 if (!t_relay())
 {
  sl_reply_error();
 }
 exit;
}

 

But when the end ua is not online,the ser proxy seems to be in a loop lock.

 

  Thanks a lot!
