You can do it "almost" automatically using RADIUS.
Install FreeRadius and have SER write records START
and STOP records to RADIUS (corresponding to INVITE
and BYE) .
What happens is that when a BYE is received, the
RADIUS looks for record corresponding to call-id (and
a couple of other checks) and it then UPDATES the
corresponding record with the Call-Termination-Time
field. So YOU GET A CDR but you do no have a SESSION
time.
So what you need to do is that you edit the freeradius
"sql.conf" file and modify the "account_stop_query"
variable to calculate the SESSION time and update the
AcctSessionTime column.
This will allow you to have the CDR with
AcctStartTime, AcctStopTime and AcctSessionTime fields
in addition to the CalledStationId and
CallingStationId (calling phone#) fields and you have
a CDR.

Hi all
i'm looking for a free/opensource application that
generates CDRs (not XDRs,
must not be rated) from the accounting data/events
generated by SER (i think
this is usually called normalization). I think this
would have to be an
application that is able to match INVITEs and BYEs
and form CDRs with call
start timestamp, call duration and so on.
I had a look at the list of accounting software on
the iptel.org website,
but most of there applications are highly integrated
accounting/billing
solutions, far more than what i need (and also most
of them seem to be
commercial products). In the mailinglist archive i
only found some
references to CDRTool which seems also to be
commercial. Obv. there must be
a free version of CDRTool but neither i'm sure
whether it implements exactly
what i need so i could "grab it" for my own purposes
nor could i find a
place to download the free version).
Does anyone know if there is such a kind of
application available? Or any
other idea how to deal with my requirements?
Thanks a lot for your help
Frank
