  Hello.
 I would like to make a question about the carrierroute module.
 How does it work when one of the "level 0" gw's are down?.  For example ,
 this is my carrierroute table :

 +----+---------+-------------+--------+------+-------+---------------+
 | id | carrier | scan_prefix | domain | prob | strip | rewrite_host  |
 +----+---------+-------------+--------+------+-------+---------------+
 | 1  |       1 | 49          | 0      |  0.3 | 0     | de-1.carrier1 |
 | 2  |       1 | 49          | 0      |  0.3 | 0     | de-2.carrier1 |
 | 3  |       1 | 49          | 0      |  0.3 | 0     | de-3.carrier1 |
 | 4  |       1 |             | 1      |  1   | 0     | defa.carrier1 |
 +----+---------+-------------+--------+------+-------+---------------+

 1- Let's suppose "de-1.carrier1" gateway is down.  So.. any INVITE to
 that gateway will not have any answer (for the failure_route failover), how
 the module handle this?,  It tries with the others+.? 
Hi Ricardo,

no, at the moment there is no automatically failover done from the 
carrierroute module. So if you want to route your calls to another gw, 
e.g. 'de-2', you must manual re-route it to another gw/ domain in the 
failure_route block.

E.g. route to domain 0 in route[..], route to domain 1 in failure_route.

...
  2.- Now, suppose that "de-1.carrier1"
gateway is only full, so i can
 probably have a reply from the gateway (maybe a "480" message"), so the
 carrierroute module now tries with a failover route (defa.carrier1?) or
 tries with any of the other two gateways still not full? 
I suppose you mean that 'de-1' is overloaded. No, the next domain is not 
automatically entered. This deficiency is known, and will be addressed in the 
future. But this code is not ready yet for a release.

You could use the lcr module, there exist a 'next_gw' function, if you don't 
want to manually specify the failure_routes.

Cheers,

Henning
