Cassandra module - query question
by Boudewyn Ligthart 03 Sep '12

03 Sep '12

Hi, I would to query the Cassandra database for other information with either CQL or other commands. Could this be done through means of either avpops or sqlops, like an MySQL database. This could be done through an external script but I would like to utilize the connection that is already established. Thanks, Bou

Why append_branch should be called in a failure route ?
by Vitaliy Aleksandrov 03 Sep '12

03 Sep '12

Below is the example from http://kamailio.org/docs/modules/3.2.x/modules/tm.htm : failure_route[0]{ if (t_check_status("5[0-9][0-9]")){ # I do not like the 5xx responses, # so I give another chance to "foobar.com", # and I drop all the replies to make sure that # they are not forwarded to the caller. t_drop_replies(); rewritehostport("foobar.com"); append_branch(); t_relay(); } } Why do append_branch() is present before t_relay(). I'm asking because I didn't used it in failure routes and call rerouting on various conditions worked great.

Catch error "status rewrite by UAS" in on_reply
by Alex Hermann 03 Sep '12

03 Sep '12

Hello all, i sometimes get a very late reply from a broken client which triggers the following error 9because the call was already continued in another branch): ERROR: tm [t_reply.c:1193]: ERROR: t_should_relay_response: status rewrite by UAS: stored: 408, received: 200 Not a problem perse, but i would like to catch this error in the script's on_reply route because I need to prevent some actions on the reply if it will not be forwarded to the UAC. Is there a way to do this? -- Greetings, Alex Hermann

Celebrating 11 Years
by Daniel-Constantin Mierla 03 Sep '12

Hello, eleven years ago, the first piece of code of the project was committed. Last year we organized a public event, for the 10 years celebration, presentations and more details about it at: * http://sip-router.org/10-years-ser/ For the 11th year, I made a news with the summary of the past year - definitively it was lot of work, adding many new features: * http://www.kamailio.org/w/2012/09/kamailio-at-11-years/ Looking forward to the next year celebration, surely it will list another great set of new features! Many thanks to everyone helping the project, from advocating to development!

kamailio and clustered database
by Vieri 01 Sep '12

01 Sep '12

Hi, I'm new to Kamailio and would like to set it up with a "circular replication database" on several servers (master-to-master). Before running 'kamdbctl create' I edited kamctlrc and set DBENGINE to MYSQL (I can use either MySQL or PostgreSQL or both - I just need to use a cluster of servers). What would you suggest? Should I set DBENGINE=MYSQL and configure a cluster of databases as described here: http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-replication-multi-mast… Or does kamailio provide another way to do the same job? What does the db_cluster module do and where/how should I use it? Thanks, Vieri

i have this piece of config code: modparam("dialplan", "attrs_pvar", "$var(plan)") ... xlog("L_INFO", "Translating <$var(calling_number)> based on dpid 4\n"); if (dp_translate("4", "$var(calling_number)")) { xlog("L_INFO", "Found attrs <$var(plan)>\n"); ... dpid 4 has three entries: 109 4 10 1 ^\+1 0 na 107 4 10 1 ^\+358 0 fi 108 4 10 1 ^\+46 0 se thus in each entry attrs field has some two letter value. when the above piece of code is executed, i get to syslog Aug 31 19:06:51 wheezy2 /usr/sbin/sip-proxy[7162]: INFO: Translating <+35892345670> based on dpid 4 Aug 31 19:06:51 wheezy2 /usr/sbin/sip-proxy[7162]: INFO: Found attrs <0> if i restart the proxy, attrs value may change to some other bogus value. any ideas? -- juha

OpenIMSCore icscf problem
by Siavash Safi 01 Sep '12

01 Sep '12

Hi, I fetched the latest source code from OpenIMSCore SVN repository and generated the debian packages on squeeze. Everything is working fine so far except the icscf module which fails to start. I think that there is something wrong with the configuration. Here is the output messages: root@spawn:~# icscf.sh Listening on udp: xxx.xxx.xxx.xxx [xxx.xxx.xxx.xxx]:5060 tcp: xxx.xxx.xxx.xxx [xxx.xxx.xxx.xxx]:5060 Aliases: tcp: spawn:5060 udp: spawn:5060 *: ims.mydomain.com:* *: icscf.ims.mydomain.com:* ------ Semaphore Arrays -------- key semid owner perms nsems root@spawn:~# 0(4597) ERROR: mk_proxy: could not resolve hostname: "" 0(4597) ERROR: fixup_hostport2proxy: bad host name in URI <> ERROR: error -478 while trying to fix configuration 0(4597) INFO:destroy_diameter_peer(): Bye Bye from C Diameter Peer test As you can see mk_proxy is called with a empty hostname! I have pasted my configuration and more verbose debug output: configuration: http://pastebin.com/nDQM1KLM debug output: http://pastebin.com/d6jh0CHF Any help would be appreciated. -- Regards, Siavash Safi Sent with Sparrow (http://www.sparrowmailapp.com/?sig)
