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

We are trying to configure the ACC module to log the Reason: header found in SIP BYE and SIP 4xx messages sent by US carriers when making calls to the PSTN. We have added a cause field (the Reason header contains the Q.850 cause code associated with telephony events, typically disconnect) to the acc and missed_calls tables (see tables description further below) and changed opensips.cfg to read that header and store it: modparam("acc", "db_flag", 2) modparam("acc", "db_missed_flag", 3) modparam("acc", "db_url", "mysql://root:password@localhost/opensips") modparam("acc", "db_extra", "from_uri=$fu;to_uri=$tu;request_uri=$ru;cause=$(hdr(Reason))") This works quite nicely for calls logged in the acc table, such as: mysql> select * from acc where date(time) = curdate() and (cause like '%850%') limit 1; +---------+--------+---------------+-----------------------+-----------------------------------------------------+----------+------------+---------------------+---------------------------------+---------------------------------+-----------------------------------+----------------+ | id | method | from_tag | to_tag | callid | sip_code | sip_reason | time | from_uri | to_uri | request_uri | cause | +---------+--------+---------------+-----------------------+-----------------------------------------------------+----------+------------+---------------------+---------------------------------+---------------------------------+-----------------------------------+----------------+ | 1903785 | BYE | 627B7414-1509 | telstage-3e5-492294f9 | 492294f9-0127-00105838-0657a1e7-22e4c653(a)88.88.88.88 | 200 | Ok | 2008-11-18 05:12:55 | sip:+5599999999@99.99.99.99 | sip:+15555555555@88.88.88.88:5060 | sip:88.88.88.88:5060;transport=udp | Q.850;cause=16 | +---------+--------+---------------+-----------------------+-----------------------------------------------------+----------+------------+---------------------+---------------------------------+---------------------------------+-----------------------------------+----------------+ 1 row in set (1.58 sec) The cause field contains "Q.850;cause=16" taken from the Reason: header.

Any advice would be most appreciated!!
