Freezing development for Kamailio v4.1.0
by Daniel-Constantin Mierla 07 Oct '13

07 Oct '13

Hello, discussed last week during IRC development meeting, we are approaching the time for getting out a new major release - to be numbered v4.1.x. I would proposed October 7 as the last day do accept new features for v4.1.0. That gives another three weeks to push new code. As a reminder, those that have personal branches with new feature, should merge asap, too. If the date is a constraint for some immediate plans, you can propose another date and we will see which fits better. Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda Kamailio Advanced Trainings - Berlin, Oct 21-24; Miami, Nov 11-13, 2013 - more details about Kamailio trainings at http://www.asipto.com -

Presence: Duplicate entry 'username-domain-presence-*#-OFFLINE-#*' for key 'presentity_idx' when multiple clients register using the same credentials
by Yufei Tao 04 Oct '13

04 Oct '13

Hi I use kamailio 4.0.3 with presence. I sometimes get these errors: Oct 4 09:26:24 server /usr/sbin/kamailio[1292]: ERROR: presence [publish.c:171]: msg_presentity_clean(): Marking presentity Oct 4 09:26:34 server /usr/sbin/kamailio[1292]: ERROR: db_mysql [km_dbase.c:122]: db_mysql_submit_query(): driver error on query: Duplicate entry 'username-domain-presence-*#-OFFLINE-#*' for key 'presentity_idx' Oct 4 09:26:34 server /usr/sbin/kamailio[1292]: ERROR: <core> [db_query.c:337]: db_do_update(): error while submitting query Oct 4 09:26:34 server /usr/sbin/kamailio[1292]: ERROR: presence [presentity.c:1281]: mark_presentity_for_delete(): unsuccessful sql update operation This is when multiple SIP clients are registered using the same credentials, they each have a presentity entry, with the same username and domain but different etags, which is fine. But when they expire, the presentity.etag will be filled with '*#-OFFLINE-#*', and when both expire at about the same time, kamailio tries to fill both with the same '*#-OFFLINE-#*' etag. Because presentity table has a 'CONSTRAINT presentity_idx UNIQUE (username, domain, event, etag)', this gives the errors. Should the constraint be removed to cope with this situation? Thank you!

difference in INVITEs when failure_route applies
by Grant Bagdasarian 04 Oct '13

04 Oct '13

Hello, Consider the following: the Dispatcher module has two destinations loaded. Now let's say we have the following two scenarios: Scenario 1: Kamailio tries to relay the INVITE to the first destination selected by the Dispatcher module, but this destination does not reply for some reason. Scenario 2: Kamailio tries to relay the INVITE to the first destination selected by the Dispatcher module, but this destination replies back with a 500 Server Internal Error. I know that in the first case, Kamailio will enter the failure_route and try to Dispatch the INIVTE to the next destination in the set. In the second case, I'm not sure, because this would require some custom code to drop the 500 reply and try the next destination in the Dispatcher set. Correct? If the second case solution is possible and Kamailio tries the next destination, which values would make the second INVITE and its replies different from the first INVITE and its replies? The To-Tag and CSeq should be different right? Any other values which Kamailio perhaps uses internally to identify/associate messages? Are these values accessible? The reason I'm asking this is because I want to log each INVITE tried as a separate call in our database and use SIP replies and in-dialog requests to update its state, but I'm doing this based on the CallID. For this to work, I need another value to make each INVITE (which have the same CallID, in case of Failover) unique. The requirements are that these values must be present for each message in a dialog. I hope I'm being clear enough. Regards, Grant

Re: [SR-Users] CDRs

Hi, I am looking to track calls so I can see which carrier they went over. I am using the LCR module to distribute calls but the CDR module doesn't tell me the final destination IP where the call was sent. Any help or advice would be appreciated. Thanks, Keith

Also I would like to try and store these numbers in a the DB somehow to minimise code.

Thanks Morten, So basically it's saying, if it matches that number and the user does not have the permission to call it then block. I am a bit unclear of the AVP stuff to be honest, is this trying to match the username to the attribute in the table? And what value does it look for in the table?

Hi, I am looking to restrict calls based on destination numbers, e.g. so people can't call premium rate etc. Which module is best to achieve this? Thanks, Keith

append_hf to reply generated by kamailio
by Grant Bagdasarian 03 Oct '13

03 Oct '13

Hello, Is it possible to append a new header to a reply generated by Kamailio and also have it present when duplicating the message to a capture server? At the moment the 603 Reply is duplicated to my capture server, but I don't know how to append a new header, because the kamailio script stops executing after exit is called. >From what I understood: onreply_route is only executed when receiving replies. Is there a reply_route which is executed for all replies, including the ones generated by kamailio itself? For instance inside this code block: request_route { ..... if($var(routing_query_result) =~ "DESTINATION_NOT_ALLOWED") { xlog("L_INFO", "[R-CORE-INCOMING-INVITE:$ci] !>" "Rejecting the call, because the destination is not allowed\r\n"); sl_send_reply("603", "Decline"); exit; } ..... }

Replace header value in failure_route
by Grant Bagdasarian 03 Oct '13

03 Oct '13

Hello, I'm trying to replace the value of a custom header in the failure_route, using the subst function. subst('/^X-Dispatcher:(.+)$/"X-Dispatcher: \$(avp(dsattrs){param.value,dispatcher})"/i'); I also tried it with the subst_hf, but that didn't work either. I'm getting the following message: 5(19536) DEBUG: <core> [re.c:454]: subst_run(): subst_run: running. r=1 5(19536) DEBUG: textops [textops.c:681]: subst_f(): lst was (nil) Does anyone have an idea what I'm doing wrong here? I'm not a regex expert, so I'm guessing there is an error in the pattern. Regards, Grant

Hi, I am looking to add some scripting to Kamailio so I can set my own variables and configure from my own web page. Anyone point me in the right direction? Thanks, Keith
