If there's not a BYE message (called party doesn't answer or timeout) then
the calling party WILL send a CANCEL. The CANCEL can be used to generate the
STOP record

If I am correct I believe CDRTool uses mediaproxy to prevent the phantom BYE
record.
Adrian can correct me if I read wrong. Invites without BYE's are common No
one answered
the phone. We just Log and drop records that dont have matching INVITE,ACK,
and BYE.
The reason as I have seen for the missing BYE (discussed alot on here) is
the UA or the Gateway
dont send a BYE for whatever reason. We havent seen that many , infact not
one yet knock on wood.
We thought about just estimating and calling them one minute calls.
The problem we are having is we route some wholesale traffic thru us via
trusted IP and account for
it (Easy Part) but we also get DID's from that Company so all traffic comes
from same IP. DID's work
fine but it broke our parser. LOL was charging them for our incoming calls
OOPS!!! I guess for now
I am going to move the wholesale Trusted IP stuff to its own box.

Do i get this right - the matching is just done by searching a matching
INVITE for each BYE where matching means that the callid must be the same?
Anf of course by calculating the callduration, normalize certain fields
and
"grap" phonenumbers out of the sip uri?
Is it really that "simple"? Since, on one hand side, i read about cases
where there is no BYE at the end of a call (i think it had to do with
mediaproxy), on the other hand side, when i look at "my" acc table, i can
find some records, where there are multiple BYEs with the same callid or
INVITEs without a BYEs.
I understand, that missing BYEs primarly are a problem of the accounting,
not of the normalization, but, how ever, i'm quite sure that i won't be
possible to have a 100% accurate accounting so i thought that there might
be
the need/possibility to do some "fixing" during normalization. I.e. i
think
i understood that the commercial version of CDRTool does so for missing
BYEs?
Am i completely wrong?
Regards
Frank

The downloadabe CDRTool gives you nothing practical.
You can not do anything useful with it. So I would not
waste my time on that.

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
