[OpenSIPS-Users] Forking accounting

[Bogdan-Andrei Iancu]

Hi Ibrahim,

For the second leg (from DID to FWD number) the problem seams to be 
setting the destination part, because of the multi destination. The 
error is you push all the destinations into dst_leg AVP - note that AVPs 
are per transaction and not per branch!

What you can do is to set the dst_leg AVP when the call is completed and 
you know what is the final destination. Use on reply route to set the 
final dst_leg:

onreply_route{
    if (t_check_code("2[0-9][0-9]")) {
          $avp(s:dst_leg)= $T_ruri;
    }
}

NOTE this will work only with 1.5 ; see 
http://www.opensips.org/html/docs/modules/devel/tm.html#id268019 for $T_ruri

Also, because you use AVPs in onreply route, enable this in TM: set 
onreply_avp_mode  to 1:
