Here is a problem I am sure is not new (1.5.x): modparam("acc", "db_extra", "gateway_id=$avp(s:gateway_id)") route { ... $avp(s:gateway_id) = 13; $ru = "some.gw1"; t_on_failure("1"); if(!t_relay()) sl_reply_error(); } # Serial forking rollover route failure_route[1] { if(t_was_cancelled()) exit; $avp(s:gateway_id) = 14; $rd = "some.gw2"; append_branch(); t_relay(); } The problem is, when serial forking happens, the CDR rows in 'acc' still show a value of 13 for 'gateway_id'. This is obviously because the value is sampled at the time of the initial stateful relay processing and is not updated afterward. Any easy/elegant fix? I can think of several fixes that don't involve using 'acc', obviously, but I'd rather avoid that... -- Alex Balashov - Principal Evariste Systems LLC Tel : +1 678-954-0670 Direct : +1 678-954-0671 Web : http://www.evaristesys.com/
