[OpenSIPS-Users] www_challenge never sends response to REGISTER

[Derek]

Opensips is never sending the 100 Trying or the failure response to the 
SIP Register.  I have including the config file that I know is ran, the 
SIP REGISTER request as taken from tcpdump and the snippet from the log 
file.  Thanks for your help.

Here is the configuration file:

                xlog("L_INFO", "Sending 100 Trying\n");
                sl_send_reply("100", "Trying");
                xlog("L_INFO", "Checking authorization\n");
                if (!www_authorize("", "subscriber"))
                {
                        xlog("L_INFO", "Challenging\n");
                        www_challenge("[domain]", "1");
                        exit;
                }

Here is the register request:
