The flag will prevent duplicates. Which version are you using, there was a patch a few months ago The explanation shold be that you are resetting them. Are you using the following, one option to confirm that your logic is good is add one log line at INFO / NOTICE level logging each time you reset the flag including the call-id : if (t_precheck_trans()) { t_check_trans(); exit; } On Wed, Feb 12, 2020 at 4:13 AM Voip support <voipexpert0(a)gmail.com> wrote:

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.

I have this code in very beginning of Request route of kamailio.cfg # handle retransmissions if (!is_method("ACK")) { if(t_precheck_trans()) { t_check_trans(); exit; } t_check_trans(); } I think its left from the default config - i changed only few things in default config to add calls per second limit / dispatcher some routing logic but nothing more and set the flags for ACC module to save. śr., 12 lut 2020 o 22:03 Voip support <voipexpert0(a)gmail.com> napisał(a):

Just to clarify my input, I am not personally using the exact accounting setup. I know that the modules using the ACC module API are all benefiting from the flag checks in the ACC module, but I am not 100% sure about this one for example. (since it is directly in the ACC module is could potentially behave differently) modparam("acc", "log_missed_flag", 12) However, I am assuming they also behave as expected, I would suggest to double check your flags interaction (by using logs) and definitions, once you are sure we may consider that there could be a bug.

5.3 yes the patch I had in mine is in. It seems like what you are doing is fine. We do not see the definition of your FLAGS in you example I am assuming they are not overlapping another flag "bit" that could be used by another module etc. There could be a concern that the same flag as multiple purpose and alias/definition. By reset I meant calling setflag multiple times : modparam("acc", "log_missed_flag", 12) ... setflag(12) On Wed, Feb 12, 2020 at 1:07 PM Voip support <voipexpert0(a)gmail.com> wrote:

Setflag is only setting the value of a transaction flag to true. We always need to make sure each flag as a unique integer value (It will be the bit position in an int32) Example: #!define FLT_ACCMISSED 2 The value 2 must not be used by any other flag, this is one thing you need to verify. The transaction module TM will "callback" the ACC module on receiving responses and the ACC module will generate an ACC event and set the flag to false, next time it will receive a transaction response, it will have its corresponding flag set to false and will not generate an new event. Q: Only one flag FLT_ACC FLT_ACCMISSED should be set for one dialog? When i do twice FLT_ACC i can have duplicate records? A: You can only the flag that is set in the modparam/acc they should be different. A: No, unless you set the flag again (in another routing script execution), setting it multiple times in the same routing script execution as no impact.
