Re: [SR-Users] Kamailio 3.0 cann't access the RTPProxy
by Daniel-Constantin Mierla 22 Oct '10

22 Oct '10

Hello, apart of the email with logs, or private data that was required, please continue the discussion on public mailing list. I need some time to check the logs, the first inconvenience is the rar archive, a zip or tgz is much better -- not a fan of installing binaries from unknown companies on mac os x, going to get unrar from macports. Then solaris is not an OS i have at hand nor use frequently, so need to read about. It is also why using mailing list keeps you in touch with others that can help.

mtree memory comsumption question
by anthony thomas 13 Oct '10

13 Oct '10

Hello list, I have been testing the new mtree module but I am a little bit confused about the results. On my tests, I randomly generated 500K, 1M and 2M entries in a table in several trees. The size of the db (on disk) ranges from 120 megs to 270 megs and when Kamailio loads it in memory, it jumps from 1.0Gb to 2.8Gb. Is there any way to pre-calculate the total amount of memory that a tree will need? Thanks, A

Problem with ser - INVITE size problem tcp->udp?
by Simone Felici 11 Oct '10

11 Oct '10

Hello to all! I need a little help with our ser installation (ser-2.0.0-rc1). The continuous groving up of our infrastructure and using even more codecs, causes the INVITE (udp) to be over 1500bytes. An external->incoming call to our proxy sip comes in with a size of ~1300 and will be forwarded to the end device (sua) over 1500. Ser is adding more than 200bytes in the udp packet. I can see 'INVITE' from ser to customer, but the INVITE is not answerred due the size. I'm sure about that, because in certain situations, deleting codec list the packet-size goes under the 1500bytes and all works. To main issue is from external calls to ser server to our customers. Calls started from customers to ser and then out are all ok. Now the question: Could the passage from UDP to TCP solve the issue? Could someone give me an example and how implement it into our ser configuration? The atteched configuration, ser on a mysql basis, is working well in expect the issue described. Thank's a lot for your help! Simon

Evaluate Perl Return Value in Routing Logic
by "Nicolas Rüger" 08 Oct '10

08 Oct '10

Hello, is there any way to use or evaluate the return-statements of a perl-script in kamailio.cfg? I tried the following in the Routing Logic in kamailio.cfg: if (is_method("INVITE")) { if (perl_exec("my_perl_subroutine") == -1){ xlog("PERL returns -1 \n"); } } Doesn't work. The bad thing is that the return-values of the - perl_exec("XXX") - call are not the same that the perl subroutine "XXX" returns. That's at least what I strongly believe after testing. I do need to read/evaluate the return-value of the perl-subroutine in the Routing Logic to define different routes depending on what the perl-subroutine returns. Is there any way to do that??? Thank you for your help in advance. Regards, Nicolas -- GRATIS für alle GMX-Mitglieder: Die maxdome Movie-FLAT! Jetzt freischalten unter http://portal.gmx.net/de/go/maxdome01

kamailio 3.0.3 tls problems
by Rouskol Andrey 07 Oct '10

07 Oct '10

Hello, I have a problem running kamailio with tls support. I can successfully register only for the first time, all further registration fails with the following message in the log: Sep 28 11:53:55 siptest /usr/sbin/kamailio[16963]: ERROR: tls [tls_server.c:392]: SSL error:error:07064041:memory buffer routines:BUF_MEM_grow:malloc failure The system is a default kamailio installation on a Debian 5.0.6 system. Does somebody know what could cause the problem? Regards, Andrey.

Problem with debug memory: kill -SIGUSR1 doesn't work fine
by César Pinto Magán 06 Oct '10

Hello, We had been experiencing memory leaks issues with our Kamailio deployment. Some of the process started to use all their assigned memory and arises allocation memory errors.

Now I was trying to check the memory status of the process (in order to see if the problem is arising again) with "kill -SIGUSR1" but now only show the memory status of the shm and the memory of the attendant process (the one who launch the other ones). I had tried to send the signal to each of the son process but I see nothing in the log. Is this a new bug or is that there is other new way to see the memory status of the processes?

Tutorial: SIP SIMPLE Presence Made Simple with Kamailio 3.1
by Daniel-Constantin Mierla 05 Oct '10

05 Oct '10

Hello, I published a tutorial of how to implement a SIP SIMPLE Presence & XCAP server with latest Kamailio/SER version. You can find it at: http://bit.ly/btrJij Last build of SIP Communicator softphone was used to exemplify some use cases. xcap_server is a new module in upcoming v3.1.0, I have tested it with several SIP clients, but I have to say is not easy to find one that implements many presence & xcap extensions (filled already couple of bugs so far). So consider it a young component by now, however, with it inside our SIP server, deploying a SIP presence server becomes trivial. Hope is helpful, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

"Create Certificates to be used with Kamailio" changes
by Juha Heinanen 04 Oct '10

04 Oct '10

now that 3.1 has async tls support, i decided (first time ever) to try to test tls. things went quite smoothly when i followed "Create Certificates to be used with Kamailio" document http://kamailio.org/dokuwiki/doku.php/tls:create-certificates#using_the_cer… during the process, i fixed a typo in the doc, added two comments to cfg part: enable_tls=1 tcp_async=no # do not include in 3.1 listen=udp:0.0.0.0:5060 listen=tcp:0.0.0.0:5060 listen=tls:0.0.0.0:5061 # not needed in 3.1 and fixed wrong file references in client configurations: eyebeam: copy the CA certificate (/etc/certs/demoCA/cert.pem) to the Windows PC and add it to the Windows certificate store (Start→Control Panel→Internet) QjSimple: copy the CA certificate (/etc/certs/demoCA/cert.pem) to the client PC and configure QjSimple to use this CA (“TLS CA file” and “verify TLS server certificate) earlier the paths pointed to certs/sip.mydomain.com files, which i think were wrong. at least i was not able to get them working. perhaps someone who is more familiar with tsl stuff could verify the above changes. -- juha

XCAP 3.1 configuration !
by X- x -X 01 Oct '10

01 Oct '10

Hi Daniel, Im a kamailio 3.1 (testing noobie) Im trying to setup a simple buddy list supporting presence server. (I gather xcap is the way to go) The simple presence thingy works nicely & instantly (thanks to those #!defines ) But I haven't been able to get this configuration going http://sip-router.org/docbook/sip-router/branch/master/modules_k/xcap_serve… I mean loading the modules & setting the modparams is a snap but this routing logic always gets to me. (i.e. those filing off .......... lines in the the routing logic section. Did I mention I was a noobie especially of routing logic section ?) Anyway you have also added this declarative #!ifdef WITH_XHTTPAUTH with in that section, where as its missing in the top section of the kamailio.cfg file. Pasting just about anywhere (or in the end before the } doesn't work for me. Could u be kind enough to elaborate a little more on that or come up with a fuller kamailo.cfg sample file. Thanx & Regards --

The jabber module is obsolete and it still exists in both (s) and (k) module version. We should remove this module from the upcoming 3.1 release. Regards, Ovidiu Sas
