[OpenSER-Users] Logging failed registration attempt

[Edoardo Serra]

Hi all,
	I'd like to log failed SIP REGISTER attempt either with xlog or with 
sip_trace() but I cannot understand where to put related code to catch 
the authentication error

Here is the part of my opensr.cfg dedicated to REGISTER handling

if (method=="REGISTER") {
         if (!proxy_authorize("exorsa", "openser_view")) {
                 proxy_challenge("exorsa", "0");
                 exit;
         }
         if (!check_to()) {
                 sl_send_reply("403", "Digest username and URI username 
do NOT match! Stay away!");
                 exit;
         }

         save("location");

         exit;
};


Tnx in advance

Regards

Edoardo
