Hi again, I remembered :-) but do not really understand why it works... Deleting the my.cnf from /etc (or from /usr) did the job. The acc db_extra works.

Everything is working except the acc db_extra inserts. I keep on getting that error: ERROR: db_mysql [km_dbase.c:123]: db_mysql_submit_query(): driver error on query: Incorrect integer value: '' for column XXXXXXX I must confess, I managed to solve the problem once. But I do not remember how :-(. The XXXXXX column is set as an integer with NULL enabled and no default value (which works on the kamailio server where i fixed it...) Any ideas of where it comes from?
