Ovidiu,
Ok, so now it's routing but it's not selecting the carrier by matching the source IP address in the subscriber table against the IP address of the incoming INVITE. Is that even possible?
If it's not possible, how do I have a different routing table for each OpenSER system? I was going to use my carrier as my OpenSER instance.... that would have worked...
I have these tables...
mysql> select * from carrierroute;
+----+---------+-------------+--------+------+-------+--------------+----------------+----------------+---------+
| id | carrier | scan_prefix | domain | prob | strip | rewrite_host | rewrite_prefix | rewrite_suffix | comment |
+----+---------+-------------+--------+------+-------+--------------+----------------+----------------+---------+
| 1 | 0 | | 1 | 1 | 0 | 200.1.1.1 | | | NULL |
| 4 | 0 | | 2 | 1 | 0 | 200.1.1.2 | | | NULL |
| 5 | 0 | | 3 | 1 | 0 | 200.1.1.3 | | | NULL |
| 9 | 1 | | 1 | 1 | 0 | 100.1.1.1 | | | NULL |
| 10 | 1 | | 2 | 1 | 0 | 100.1.1.2 | | | NULL |
| 11 | 1 | | 3 | 1 | 0 | 100.1.1.3 | | | NULL |
+----+---------+-------------+--------+------+-------+--------------+----------------+----------------+---------+
6 rows in set (0.00 sec)
mysql> select * from route_tree;
+----+-----------+
| id | carrier |
+----+-----------+
| 1 | Hong Kong |
| 0 | default |
| 2 | San Jose |
+----+-----------+
mysql> select username, domain, cr_preferred_carrier from subscriber;
+----------+----------------+----------------------+
| username | domain | cr_preferred_carrier |
+----------+----------------+----------------------+
| | 192.168.255.53 | 2 |
| | 192.168.1.240 | 1 |

finally you got it ;)

add a 'default' carrier into the route_tree table
