[Freeswitch-users] Log of Authentication Attempts/Failures

Hello Guys, I am trying to log the attempts and failures of the authentication process but I am not able to get the log as described in the freeswitch site. I have already set my profile to log it by doing: <param name="log-auth-failures" value="true"/> and I reloaded the sofia mod. I should get in the freeswitch log, "SIP auth challenge" or "SIP auth failure", but I am getting only "Send challenge for" and "Send forbidden for" if the authentication fails. I am using the freeswitch version 1.2.11. What else should I do? Regards, Gustavo
