Hi Ruchir,

with multi-leg accounting, you can match all the records belonging to the same call by using call_id, to_tag and from_tag. How you format and store the CDRS is your choice :).

Yeah I just noticed that INVITE & BYE time difference gives accurate duration of the call. We can drop using ACK now :)
Are there any standards for storing records for multi-leg accounting? I tried to find it but didn't get success. Can you please suggest which way we should store CDR to identify the records properly?

Well, depends of how you process the ACC infor for building CDRs -
that was more an opinion/recommendation than a must :).

Regarding the ACK and call duration -- actually the media starts
to flow immediately after the 200OK (when the INVITE log is
generated) - most of the devices wait for ACK as confirmation that
everything is ok and not for starting the call.

I was thinking it should generate 9 records so it'll show up
as 3 different calls so we can show CDR properly in web
interface as well as calculate billing for users as the user
who forwarded the call should be charged for the call. Also if
we get INVITE only then we may not get accurate duration of
call as actual duration starts when callee accepts the call
and ACK is received. Is this scenario wrong?

Perfect !

regarding multi-leg calls - first of all, there is no need to
enabled in for ACK and BYEs - make no sense. usually you
want to
see all the legs of the call for INVITE.

Now, about how many records you get - depends on how many AVPs
(used of multi-leg acc) you set from the script. If you 3
INVITEs,
means you add 3 values for at least of the AVPs .

I had put setflag after t_newtran() previously. Now I
moved it
before t_newtran() and got records for INVITE, ACK &
BYE for
normal call perfectly. :)
Then I tested for call forwarding scenario. In this case
forwarding is set as below:
90004 -> 90001 -> 90003.

I called 90004 from 90002 and I got 7 records in acc
table. 3
INVITEs, 3 BYEs and only single ACK. Shouldn't it log 3 ACK
messages?

Be sure you set the accounting flag before any
t_relay() or
t_newtran() for the INVITE. To be sure, try to use
log/xlog
to put
some debugs in your script and check if the flag is
really set
before t_relay().

I configured simple acc module to store records
in acc
table,
set proper flags. Then tried to call number
directly(not with
forwarding) but still I get only BYE record. Any
suggestion?

Hi Ruchir,

There are two aspects here:
1) making acc to work - setting the flags and
getting the ACC
records
2) enabling multi-leg account and putting more
info into the
accounted info

First you should to solve (1) - just getting a
simple ACC
record
for INVITEs and BYEs (no multi leg
accounting) - it this
working
for you or you get only BYE acc?

Bogdan

Hi All,

I'm trying to configure OpenSER with
multi-leg
accounting. I'm
using OpenSER 1.2 & radius. I'm using
acc_radius
table for
writing cdr records. I've searched through
several articles
and mailing list posts about configuring
multi-leg
accounting
and everywhere they talk about setting up
multi-leg-info
parameter of acc module to configure leg
source &
destination
and setting up accounting flag. But this
is not
working for
me. I get only BYE record in table if I
use this
way to
write
multiple records for one call in call
forwarding
scenario. I
managed to get multiple records by calling
acc_rad_request on
INVITE, ACK, BYE & CANCEL. For instance,
I have
4 users;
90001, 90002, 90003, 90004. The call
forwarding is
setup as below:
90004 -> 90001 -> 90003.

I dial 90004 from 90002 user and it
forwards the
call
to 90001
& then 90003 and they're connected properlry.
However I
don't
get leg source/destination properly and
also I
get 7-8 bye
records for this call. Can anyone guide
me in right
direction
if I'm doing anything wrong.

Regards,
Ruchir
