[Kamailio-Users] ACC module issue logging Reason: SIP header in missed_calls

Hello,
the acc uses the SIP request to get the attributes for logging.
It is why you get it for BYE (a sip request) and not for failed calls
where the header is in reply.
Anyhow, there are couple of solutions to get it:
- store the header in an avp (in route for BYE and in onreply_route for
replies) and set tm parameter:
http://kamailio.org/docs/modules/1.4.x/tm.html#id2506328
- if you don't have parallel forking, then you can use $var(...) instead
of avp (a bit faster)
Cheers,
Daniel
