Hi everyone,

I have some troubles using acc_json module. I can't load it and I don't understand why it fails.
The configuration is quite basic: Debian 10 and Kamailio (fails in 5.5 and 5.6) installed using APT repository.

Here is parts of my config:

loadmodule "kex.so"
loadmodule "corex.so"
loadmodule "tm.so"
loadmodule "tmx.so"
loadmodule "rr.so"
loadmodule "pv.so"
loadmodule "dialog.so"
loadmodule "acc.so"
loadmodule "acc_json.so"
modparam("acc_json", "cdr_enable", 1)

I also tried with those 4 additionnal settings with no success:

modparam("acc_json", "cdr_output_syslog", 1)
modparam("acc_json", "cdr_log_facility", "LOG_LOCAL3")
modparam("acc_json", "cdr_enable", 1)
modparam("acc_json", "cdr_expired_dlg_enable", 1)

As soon as I set cdr_enable to 1, it displays the "cannot register ACC CDR JSON engine".

Here is logs:

May it be related to the Jansson version ? I use the native one from Debian 10, v2.12.
Do you have any advice, or some tips to debug my issue ?

I don't really want to use acc module and parse CDRs manually from syslog, json is far easiest for this job.

Thank you
