HiAll,
As additional step I tested the scenario with kamailio v5.1.5 but the
problem seems still there.
Best regards.

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: acc [acc_extra.h:63]:

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
