[SR-Users] ACC module

Dear Community, I have setup ACCDB module to save missed / failed and successful calls. My issue is that i am getting duplicated entries for INVITE / BYE in acc database table. For example: id;method;from_tag;to_tag;callid;sip_code;sip_reason;time;src_ip;dst_user;dst_domain;src_user;src_domain;cdr_id 231838;INVITE;21-7FC1D85;1914472180948750;KKyIdaaJceAu7pzN(a)172.16.0.35;200;OK;2020-02-11 19:16:28;22.33.44.55;nlb124#78019989897056;11.11.11.11;asterisk;172.16.0.35;0 231839;INVITE;21-7FC1D85;1914472180948750;KKyIdaaJceAu7pzN(a)172.16.0.35;200;OK;2020-02-11 19:16:28;22.33.44.55;nlb124#78019989897056;11.11.11.11;asterisk;172.16.0.35;0 231840;INVITE;21-7FC1D85;1914472180948750;KKyIdaaJceAu7pzN(a)172.16.0.35;200;OK;2020-02-11 19:16:28;22.33.44.55;nlb124#78019989897056;11.11.11.11;asterisk;172.16.0.35;0 231841;BYE;21-7FC1D85;1914472180948750;KKyIdaaJceAu7pzN(a)172.16.0.35;200;OK;2020-02-11 19:16:36;22.33.44.55;;190.196.153.130;asterisk;172.16.0.35;0 231842;BYE;21-7FC1D85;1914472180948750;KKyIdaaJceAu7pzN(a)172.16.0.35;200;OK;2020-02-11 19:16:36;22.33.44.55;;190.196.153.130;asterisk;172.16.0.35;0 231844;BYE;21-7FC1D85;1914472180948750;KKyIdaaJceAu7pzN(a)172.16.0.35;200;OK;2020-02-11 19:16:36;22.33.44.55;;190.196.153.130;asterisk;172.16.0.35;0 Following way: # ----- acc params ----- /* what special events should be accounted ? */ modparam("acc", "early_media", 0) modparam("acc", "report_ack", 0) modparam("acc", "report_cancels", 0) /* by default ww do not adjust the direct of the sequential requests. * if you enable this parameter, be sure the enable "append_fromtag" * in "rr" module */ modparam("acc", "detect_direction", 0) /* account triggers (flags) */ modparam("acc", "log_flag", FLT_ACC) modparam("acc", "log_missed_flag", FLT_ACCMISSED) modparam("acc", "log_extra", "src_user=$fU;src_domain=$fd;src_ip=$si;" "dst_ouser=$tU;dst_user=$rU;dst_domain=$rd") modparam("acc", "failed_transaction_flag", FLT_ACCFAILED) /* enhanced DB accounting */ #!ifdef WITH_ACCDB modparam("acc", "db_flag", FLT_ACC) modparam("acc", "db_missed_flag", FLT_ACCMISSED) modparam("acc", "db_url", DBURL) #modparam("acc", "db_extra", # "src_user=$fU;src_domain=$fd;src_ip=$si;" # "dst_ouser=$tU;dst_user=$rU;dst_domain=$rd") modparam("acc", "db_extra", "src_user=$fU;src_domain=$fd;dst_user=$rU;dst_domain=$rd;src_ip=$si") # our lines modparam("acc", "cdrs_table", "acc_cdrs") modparam("acc", "cdr_on_failed", 1) #!endif Then in routing config i set setflag(FLT_ACC FLT_ACCMISSED FLT_ACCFAILED in several places. My question is - each setflag cause an entry to be saved in DB? How can i debug and resolve the issue of duplicates. I am trying to use a CDR script found somewhere on siremis sites to do the accounting but it's making trouble because due to duplicates in acc table i am getting cdrs unique key violations. Secondary question is - if a BYE is not received / lost is there any way to send a check triggered by kamailio to each caller and callee side to check if dialog is still active. I would not like to use session timers (as endpoints need to support it). Best regards, Tom
