Daniel hi, In my config I don't have any authentication. I also configured in mysql the log-slow-query with long_query_time = 2 In my kamailio.cfg is a lot of ACC loging: Log acc to a file (extra fields) Log to mysql with axtra fields(I disabled this for the moment because was causing high load) Log to a Radius (the radius is in the same machine and as far as I know the radius after i swriting his data to a mysql also) I diden't know that we have radius installed localy From the log-slow-query now I see a message about sip_trace query wich obiesly took time more than 2 sec. Now I know that I'm doing also sip_trace inserts in mysql
