Hello,

you have another group of actions that can send 401 Unauthorized:

if (!check_to()) { sl_send_reply("401", "Unauthorized"); exit; }

You can either run with debug=4 and watch the syslog to see some hints in messages where it fires this 401, or use debugger module with cfgtrace option set and you see the execution path of the config in the logs.

If you send here the ngrep of such REGISTER and the reply we can spot what could be the situation for 401.

Cheers, Daniel

Hello sr-users,

I'm new using kamailio open source, and I would like to ask for help.

My version is 3.1.4 and I am trying to configure 3 servers, one with proxy, one with registrar and one with location server.

My problem is when I try to send a register message it returns an error "401 Unauthorized", I know the error is in the fuction www_authorize("10.254.239.7", "subscriber") but I don't know how to solve it, for me it seems correct the parameters.

Below I have attatched the proxy and registrar relevant route code for my problem, and the IPs for proxy an registrar are: 10.254.239.7-----------10.254.239.8

If someone can help me, I will be gratefull. Thanks in advance.

####REGISTRAR CODE

route{

   # initial sanity checks -- too long messages
   if (msg:len >=  2048 ) {
           sl_send_reply("513", "Message too big");
           exit;
   };

   if (!uri==myself) {
           sl_send_reply("400", "Bad destination, only register 

messages de$ exit; };

   # the only valid message for the registrar is the register message
   # other messages are answered with an error message
   if (uri==myself) {

           if (method=="REGISTER") {

                   sl_send_reply("100", "Trying");

           if (!www_authorize("10.254.239.7", "subscriber")) {
                   www_challenge("10.254.239.7", "1");
                   exit;
           };

           if (!check_to()) {
                   sl_send_reply("401", "Unauthorized");
                   exit;
           };

            consume_credentials();
                   if(!save("location")) {
                           sl_reply_error();
                   };
                   exit;
           } else {
                   sl_send_reply("403", "Forbidden");
                   exit;
           };
   };

}

#########PROXY CODE

           if (method=="ACK") {
            route(1);
            exit;
            } if (method=="INVITE") {
            route(3);
            exit;
            } else if (method=="REGISTER") {
            route(2);
            exit;
             };

           lookup("aliases");
           if (!uri==myself) {
                   route(1);
           };

route[2] { #rewrinting the host allows the registrar to know that the message is de$

   rewritehost("10.254.239.8");
   if(!t_relay()) {
           sl_reply_error();
   };
   exit;
