Hello, I have to take care of an old server running kamailio 1.4 (I plan to upgrade to latest, but I cannot do it at the moment). It uses carrierroute and it works fine. Now I am testing adding a new carrier and it worked. However, sometimes I get a failure to resolve a route (using cr_route): Oct 9 21:29:04 centos53-02121 /usr/local/src/svn/kamailio-1.4/kamailio[3160]: ERROR:carrierroute:cr_do_route: desired routing domain doesn't exist, prefix 99900000112233445566778899, carrier 10, domain 0 I can see the cause of the problem is because an element called "id" is solved differently sometimes when "cr_reload_routes" is issued. I am using always this same table: mysql> select * from carrierroute where carrier=10; +------+---------+--------+-------------+-------+------+------+-------+--------------------+----------------+----------------+-------------+ | id | carrier | domain | scan_prefix | flags | mask | prob | strip | rewrite_host | rewrite_prefix | rewrite_suffix | description | +------+---------+--------+-------------+-------+------+------+-------+--------------------+----------------+----------------+-------------+ | 4271 | 10 | 0 | 999000 | 0 | 0 | 1 | 6 | 192.168.2.123:5060 | | | NULL | | 4272 | 10 | 1 | 999000 | 0 | 0 | 1 | 6 | 192.168.2.123:5060 | | | NULL | +------+---------+--------+-------------+-------+------+------+-------+--------------------+----------------+----------------+-------------+ 2 rows in set (0.00 sec) When cr_route works fine, the reload logged this: Oct 9 21:31:21 centos53-02121 /usr/local/src/svn/kamailio-1.4/kamailio[7902]: DBG:carrierroute:get_route_tree_by_id: tree carrier_10, domain 0 : 0 Oct 9 21:31:21 centos53-02121 /usr/local/src/svn/kamailio-1.4/kamailio[7902]: DBG:carrierroute:get_route_tree_by_id: tree carrier_10, domain 1 : 1 But when it fails, it logged this: Oct 9 21:29:04 centos53-02121 /usr/local/src/svn/kamailio-1.4/kamailio[3160]: DBG:carrierroute:get_route_tree_by_id: tree carrier_10, domain 0 : 1 Oct 9 21:29:04 centos53-02121 /usr/local/src/svn/kamailio-1.4/kamailio[3160]: DBG:carrierroute:get_route_tree_by_id: tree carrier_10, domain 1 : 2 So I understand that the problem is a mismatch between a value that is produced by kamailio when I ask for a domain (named '0' and '1') and value of id that probably was computed based on domain at the time the route_tree was created. So, I was thinking, maybe domain names '0' and '1' would not be good for this and I should use some longer names. Well i should not expect a domain named '0' to always result in an id=0. But I would expect that whatever id is resolved, it should happen equally for both values being matched that came from the same base element (supposedly, the domain name). I will test using longer names anyway, but since this problem doesn't happen everytime I do cr_reload_routes, I was hoping to get an opinion about it. Regards, Takeshi
