Hello. I'm facing a problem with the carrierroute module (openser version 1.3.2). i hope that someone could help me. I have two gateways for a particular destination. GW1and GW2 :

+----+---------+-------------+--------+------+-------+---------------+----------------+----------------+--------------+ | id | carrier | scan_prefix | domain | prob | strip | rewrite_host | rewrite_prefix | rewrite_suffix | comment | +----+---------+-------------+--------+------+-------+---------------+----------------+----------------+--------------+ | 1 | 0 | 200 | 0 | 0.3 | 0 | GW1.IP | | | op 1 | | 2 | 0 | 200 | 0 | 0.3 | 0 | GW2.IP | | | op 2 | | 3 | 1 | 200 | 1 | 1 | 0 | GW3.IP | | | op 3 | +----+---------+-------------+--------+------+-------+---------------+----------------+----------------+--------------+

Let's say, for example, that GW1 is down (offline). Is possible via the carrierroute module try with the other gateway (GW2) before sending the call to the failure_route?. My configuration file is very similar to the example in the docs.

route[2] { # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { sl_reply_error(); }; exit; }

route[5] { # CARRIER ROUTE MODULE HANDLING.

# route calls based on hash over callid # choose route domain 0 of the default carrier

if(!cr_rewrite_uri("0", "call_id")){ sl_send_reply("403", "Not allowed - CR"); } else { # In case of failure, re-route the request t_on_failure("2"); # Relay the request to the gateway route(2); } }

failure_route[2] { # In case of failure, send it to an alternative route: if (t_check_status("408|5[0-9][0-9]")) { #choose route domain 1 of the default carrier if(!cr_rewrite_uri("1", "call_id")){ t_reply("403", "Not allowed"); } else { route(2); } } }

How can i address this issue?

Thanks,
