[SR-Users] Fwd: configuration

[Daniel-Constantin Mierla]

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
