I’m looking for a way to distinquish between locally generated 408s triggered by the timers. My problem is that I’m using gateway failover in a failure route and on 408s it would retry phones multiple times if they didn’t answer (no voicemail etc) – so fr_inv_timer was triggered after receiving a provisional reply. I need to failover in case a gateway doesn’t respond with provisional (it’s set at 5 seconds currently).

Will this work, is there a cleaner solution? I haven’t had the oppurtunity to test it so I may have some syntax errors.

onreply_route {

            if (t_check_status("1[0-9][0-9]")) {

                xlog("L_NOTICE", "KAM_HOST: ($ci) $pr $mi route[$rm][0] $fu TO $ru -> Provisional Response --> $T_reply_code\n");

                setflag(FLAG_PR_RECEIVED);

        }

}

failure_route[ROUTE_DP_FAILURE] {

            if (t_local_replied("last") && t_check_status("408") && isflagset(FLAG_PR_RECEIVED)) {

                        xlog("L_INFO", "KAM_HOST: ($ci) $pr $mi route[$rm][0] $fu TO $ru -> Local 408 after provisional response, giving up\n");

                        exit;

            }

}

Thanks!
