[Kamailio-Users] tcp_blocking_connect related errors and Kamailio using 100% CPU
by Pascal Maugeri 29 Jan '10

29 Jan '10

Hi Using Kamailio 1.5 we periodically get the following errors: Jul 1 09:54:41 localhost /usr/local/sbin/openser[3836]: ERROR:core:tcp_blocking_connect: poll error: flags 18 Jul 1 09:54:41 localhost /usr/local/sbin/openser[3836]: ERROR:core:tcp_blocking_connect: failed to retrieve SO_ERROR (110) Connection timed out Jul 1 09:54:41 localhost /usr/local/sbin/openser[3836]: ERROR:core:tcpconn_connect: tcp_blocking_connect failed Jul 1 09:54:41 localhost /usr/local/sbin/openser[3836]: ERROR:core:tcp_send: connect failed Jul 1 09:54:41 localhost /usr/local/sbin/openser[3836]: ERROR:tm:msg_send: tcp_send failed They are several emails in this mailing list explaining we should play with tcp parameters. I will try to change my configuration and see if we can solve this issue. But when this kind of error happen we observe that the kamailio processes are using 100% of CPU (top). Our client is using SIP over TCP only (no UDP). Do you have any hint on how to configure Kamailio to improve TCP support ? Is it normal to kamailio processes to overload CPU ? Regards, Pascal

Hi, I solved the problem within snom370 registration with TLS: It was necessary to set the TLS-Modul Parameter "cipher_list" to RSA. Now the snom 370 registers via TLS. Thanks Klaus! regards Andreas

by Daniel-Constantin Mierla 29 Jan '10

29 Jan '10

Hello, should we package kamailio 1.5.4? 1.5.3 was in october last year, there were some commits around since then. Next week monday? 1.4.x got out of maintenance period, should we do the 1.4.5 (just release tarballs) to mark that? Cheers, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/

[Kamailio-Users] new feature: geoip location in cfg
by Daniel-Constantin Mierla 29 Jan '10

29 Jan '10

Hello, a new module was uploaded to master branch to lookup ip addresses against a geoip database. The module supports many lookups at the same time and returns the details in pseudo-variables. Therefore a new pv class: $gip(pvc=>key). pvc is the id of the container where to store the results of a geoip search, key is an id for the attribute you want to receive. See details on wiki: http://sip-router.org/wiki/cookbooks/pseudo-variables/devel#geoip_module_ps… Readme of the module: http://sip-router.org/docbook/sip-router/branch/master/modules/geoip/geoip.… Cheers, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/

[Kamailio-Users] documentation team
by Daniel-Constantin Mierla 29 Jan '10

29 Jan '10

Hello, following some discussions on users mailing list, seems we may get a group of people willing to digest documentation and contribute to modules' readme or wiki pages. Hopefully Alex Balashov (who volunteered so far) would have some time to coordinate contributions to git docs, for wiki being easier, as anyone has access. I am willing to help as much I can, but time is always a constraint for a dev. I invite you to join IRC channel #sip-router hosted on freenode.net to plan an synchronize easier. Thanks, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/

Request for a special parallel + serial forking scenario
by Klaus Feichtinger 29 Jan '10

29 Jan '10

Hi, I have a special question regarding a mixture of parallel and serial forking, operated by Kamailio-3.0.0. First of all I will give you a short background information, what the target will be: I have a SIP-server on place A, 3 gateways on place B and 3 gateways on place C). These gateways are registered on SIP server (A) with different Q-values (e.g. GW-B1=1.0, GW-C1=1.0, GW-B2=0.8, GW-C2=0.8, GW-B3=0.6, GW-C3=0.6). The target is, that a call for a gateway MUST be signalled on place B and C in parallel (forking) until the call is finally established over one of the two involved gateways on place B or C. When the prime gateway(s) (with the highest Q-value) fail (e.g. they do not send a provisional response within a timeout or send a negative response), the next gateway(s) should be addressed (with the next lower Q-value), a.s.o. The configuration works well in case that both gateways on place B and C fail at the same time (BOTH do not send a response or BOTH send a negative response or one does not send a response and the other one sends a negative response). However, in case that only ONE of the two (always in parallel) addressed gateways fails, it does not work as expected. It does nothing and/or waits for an eventually negative response or the call setup timeout. Configuration is done as described in the README of the TM module. It is a mixture of the main route and a failure_route in combination with the functions t_load_contacts() and t_next_contacts(). Does anybody have an idea how this problem could be solved or any alternative solution for this special requirement of parallel signalisation in any case? Thanks in advance!

[Kamailio-Users] rtpproxy session is not automatically deleted if INVITE transaction fails?
by Iñaki Baz Castillo 28 Jan '10

28 Jan '10

Hi, I'm realizing that rtpproxy session is not automatically terminated when an outgoing INVITE transaction fails ([3456]XX response received from downstream), so the rtpproxy session dies after a while due to time expiration. So I've added the following code to my on_reply_route: ------------ onreply_route[X] { if is_method("INVITE") && status =~ "[3456][0-9][0-9]" unforce_rtp_proxy(); ------------ It seems to do the job. However I expected this to be done automatically by rtpproxy module when an INVITE transaction for which a rtpproxy session has been created fails. Do I miss something? or is it the expected behavior? Thanks a lot. -- Iñaki Baz Castillo <ibc(a)aliax.net>
