[Serusers] ser2.0 - logging missed calls

Hi all, I need help with logging of missed calls for offline users. acc_db module is loaded but acc_db_missed function unrecognized. I tired to use this function with ser2.0_rc1 and latest ser-2.0.0+cvs20080709 but the error is same. Or could I solve this in some other way? And if someone could point me to acc_db module documentation because I can't find it on iptel.org site. Thank you /davor ser -V version: ser 2.0.0+cvs20080506 (i386/linux) ... loadmodule "/usr/local/ser_20_06052008/lib/ser/modules/mysql.so" loadmodule "/usr/local/ser_20_06052008/lib/ser/modules/acc_db.so" modparam("acc_db", "db_url", "mysql://ser:heslo@localhost/ser") modparam("acc_db", "log_missed_flag", 4) ... if (lookup_contacts("location")) { . . . } else { acc_db_missed("480 - User temp. unavail.", "missed_calls"); sl_reply("480", "User temp. unavail."); drop(); } ... 0(23273) find_export_record: <acc_db_missed> not found 0(23273) parse error (1116,46-47): unknown command, missing loadmodule? /davor
