Subject: [Kamailio-Users] help using rewrite prefix

I need help setting up carrierroute using the rewrite prefix and the strip function.  It seem like every time I use the Rewrite Prfix function the carrierroute module will rewrite the prefix, but then I don't get certain reply messages on kamailio. At least from what I can see on the log.

 INFO:carrierroute:cr_do_route: uri 5555550001 was rewritten to sip:0115555550001 at aslab.commx.net, carrier 1, domain 10
 INFO:carrierroute:rewrite_uri_recursor: URI or prefix tree nodes empty, empty rule list
 INFO:carrierroute:cr_do_route: rewrite_uri_recursor doesn't complete, uri 0115555550001, carrier 1, domain 10

Is this normal behavior?  I also noticed that some messages coming back from the host are not being processed by kamailio. For example on this particular call I purposely  get a 604 from the server. The thing is I can't process a failure route for this message, because kamailio doesn't see is, even though it is being sent back to the server.

Also when I use the Strip function is looks like carrierroute does a second lookup on the route table. In the example below I am calling a number using the prefix 551... The route table is below.

+----+---------+--------+--------------+-------+------+------+-------+-----------------+----------------+----------------+------------------------+
| id | carrier | domain | scan_prefix  | flags | mask | prob | strip | rewrite_host    | rewrite_prefix | rewrite_suffix | description            |
+----+---------+--------+--------------+-------+------+------+-------+-----------------+----------------+----------------+------------------------+
| 30 |       1 |      1 | 551          |     0 |    0 |    1 |     2 | 10.10.10.1    |                |                | LD-1
| 31 |       1 |      1 | 1            |     0 |    0 |    1 |     0 | 10.10.10.1     |                |                | LD               |


Log for that call
INFO:carrierroute:cr_do_route: uri 5515555550004 was rewritten to sip:15555550004 at 10.10.10.1, carrier 1, domain 1
INFO:carrierroute:cr_do_route: uri 15555550004 was rewritten to sip:15555550004 at 10.10.10.1, carrier 1, domain 1
 Carrier found!! ("1", "131.226.0.144", "15555550004", "15555550004", "COMMX-LD");

Now please note that if I remove route id 31 then the call log looks like it is below:

 INFO:carrierroute:cr_do_route: uri 5515555550004 was rewritten to sip:15555550004 at 10.10.10.1, carrier 1, domain 1
 INFO:carrierroute:rewrite_uri_recursor: URI or prefix tree nodes empty, empty rule list
 INFO:carrierroute:cr_do_route: rewrite_uri_recursor doesn't complete, uri 15555550004, carrier 1, domain 1


Please help!!!

Carlos

It will also help if there was  complete routing example using carrierroute v 1.5.0, since the one in the wiki is outdated. Thanks.
