[SR-Users] db logging for unsuccessful calls

Hi to all, I could hardly make kamailio log cdr to db but it just logs successful calls.I need cdr of unsuccessful calls also.I used to use asterisk so in cdr I need duration and billsec separately.As far as I understand kamailio can give only one of them.Is there a way to get them? Here is my acc configuration: #!ifdef WITH_ACCDB modparam("acc", "cdr_enable", 1) modparam("acc", "early_media", 0) modparam("acc", "report_ack", 1) modparam("acc", "report_cancels", 1) modparam("acc", "detect_direction", 0) modparam("acc", "db_url", "mysql://root: secret@localhost/mydb") modparam("acc", "log_flag", FLT_ACC) modparam("acc", "db_missed_flag", FLT_ACCMISSED) modparam("acc", "db_table_missed_calls", "missed_calls") modparam("acc", "db_flag", 1) modparam("acc", "db_missed_flag", 3) modparam("acc", "db_extra","src_user=$fU;src_domain=$fd;src_ip=$si;dst_user=$rU;dst_domain=$rd") #!endif What should I exactly do?Can someone help? Thanks in Advance. BETÜL CERİT
