Hi,It is my second time upgrading kamailio to 4.2.X.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 XXXXXXXI 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?BR,Uri
