[OpenSIPS-Users] Forking accounting

[ibrahim tunali]

Hi Bogdan,

I have to use multileg accounting because my application records all
request leg to acc. I use mentioned issue for this scenario;

1. DID call come to my opensips and it add to multileg.
$avp(s:src_leg)=$fU; $avp(s:dst_leg)=$rU;
2. The user owner of the DID was set callforwarding to a few pstn destination.
3. I load these destinations to branch with "avp_pushto("$ru","$avp(s:fwd)/g");"
4. I had set dst_leg from on branch route;
branch_route[1]{
    $avp(s:dst_leg)=$rU;
}

I need to see only wining branch call in acc;

Method   src_leg        dst_leg
----------    ----------        -----------
INVITE    1925XXXXXX 1212XXXXXXXX (DID num)
INVITE    111              1707XXXXXXXX (CallFwd wining branch)

But i see;

Method   src_leg        dst_leg
----------    ----------        -----------
INVITE    1925XXXXXX 1212XXXXXXXX (DID num)
INVITE    111              1707XXXXXXXX (CallFwd branch1)
INVITE    111              1707AAAAAA (CallFwd branch2)
INVITE    111              1707BBBBBB (CallFwd branch3)

Best Regards,
Ibrahim TUNALI
