                <br>
                with the latest patch it works fine. The ACC record has
                code 486 and status Busy.<br>
                I'm not sure if in this case it would be better to
                report 487/Cancel or 486/Busy in the ACC, but in any
                case the record has been created.<br>
                <br>
                <br>
                Thank you very much for your help<br>
                <br>
                Regards

                                      <pre>Hi All,

I'm facing a strange problem of missing ACC record in case of
parallel call forking.

The scenario is the following:
 - A subscriber with 1 device registered
 - B subscriber with 2 device registered (B1 and B2)

CASE 1:
 - A calls B
 - B1 and B2 start ringing
 - A hangups the call before B1 or B2 answers
Kamailio generates an ACC record.

CASE 2:
 - A calls B
 - B1 and B2 start ringing
 - B1 rejects the call sending back a 486
 - B2 is still ringing
 - A hangups the call before B2 answers
Kamailio DOESN'T generate an ACC record.



We have Kamailio v5.1.4 with TM module enabled.

ACC configuration is the following:
  modparam("acc", "early_media", 0)
  modparam("acc", "report_ack", 0)
  modparam("acc", "report_cancels", 1)
  modparam("acc", "detect_direction", 1)
  modparam("acc", "db_flag", 1)
  modparam("acc", "db_missed_flag", 2)
  modparam("acc", "failed_transaction_flag", 3)


I increased debug level of TM and ACC modules and I added some debug
lines as well.
The difference between the two calls is that, after the CANCEL sent
by A is processed by Kamailio, in CASE 1 I have the following lines:
  Aug 28 14:21:11 spce proxy[13188]: DEBUG: tm [t_hooks.c:258]:
run_trans_callbacks_internal(): DBG: trans=0x7f5a88049198, callback

free_strar_mem(): Freeing memory, type is 2, message_index 8, index i 4

Those debug lines are not printed for CASE 2.



Is there any configuration I'm missing or is it a bug?



Thank you very much for your support.
Marco
