Decode contact with user paramer
by Gareth Rylance 24 Jan '13

24 Jan '13

When using the siputils function encode_contact() on a message that contains a user parameter e.g. <sip:XXXXX00015;phone-context=national@10.YYY.1.92;user=phone>;tag=88930 it encodes fine e.g. <sip:natted_ua*sip:XXXXX00015;phone-context=national**192.168.242.102*5080*udp@10.YYY.70.100 > but decode_contact() errors due to the ";" (there is an explicit check for it in the code) I am currently working round this using $rU = $(rU{s.replace,;,:}); to remove the ; as the user part is not needed for my application. Would it be safe to remove the check for ";" ? Gareth

Merry Christmas!

18 Jan '13

Another year getting to its end! Looking back, looks like one with the greatest achievements in the development of the project so far. Year is not done, so I save that summary for one week later, there is still stuff on its way to our source code repository. Now I want to thank to everyone promoting and contributing to the project, from developers to community members, and wish Merry Christmas and great winter holidays to all supporters of our project! Cheers, Daniel -- Daniel-Constantin Mierla -- http://www.asipto.com http://linkedin.com/in/miconda -- http://twitter.com/miconda

Core fm_realloc function
by Bruno Bresciani 08 Jan '13

08 Jan '13

Hi all, I observed two at 0x08173bf0 in fm_realloc (qm=0xb5f7d000, p=0xb61f0bc0, size=0) at mem/f_malloc.c:536. I don't know exactly what may be caused this core because the debug of kamailio is disabled, but looking at backtrace (gdb) and source code I could notice a relationship with TLS connection establishment (handshake). Other important fact is that core was generated by the kamalio itself with signal 6 (abort) because it can't find the pointer to memory realloc. I'd like to know if someone already observed this issue and if my analyse above is correct? Bellow is backtrace full with gdb: Core was generated by `/home2/local/kamailio/sbin/kamailio -P /var/run/kamailio.pid'. Program terminated with signal 6, Aborted. #0 0x00f30402 in __kernel_vsyscall () (gdb) (gdb) (gdb) (gdb) (gdb) bt full #0 0x00f30402 in __kernel_vsyscall () No symbol table info available. #1

TCP Path received quotes
by Spencer Thomason 07 Jan '13

07 Jan '13

Hello, I'm forwarding registrations to Freeswitch and adding a Path header using add_path_received() for endpoints behind NAT. When TCP is used, this results in a header like this: Path: <sip:a.a.a.a:5070;lr;received="sip:b.b.b.b:35430;transport=tcp"> Freeswitch doesn't like the transport protocol inside the quotations and refuses to route a call to the registered user. Constructing the header manually without the quotes such as: append_hf("Path: <sip:$Ri:$Rp;lr;received=sip:$si:$sp;transport=$pr>\r\n"); solves the problem. Is there a reason for the quotes? Best Regards, Spencer

Freezing for next major release
by Daniel-Constantin Mierla 04 Jan '13

04 Jan '13

Hello, based on last irc devel meeting and feedback afterwards, most of the people seem to be fine releasing next major release a bit earlier, in order to: - make websockets support and the other new features available in a stable version - allow proper development time frame for other planned new features that wouldn't have been ready if the release would be 1-2 months later So, considering the winter holidays, I propose to freeze development on January 7, 2013, with full release about one month later. It seems that many people are already using devel version to play with websockets, meaning that we are staying very well with testing. Other opinions? Cheers, Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

recreating kamilio_fifo without restart
by Uri Shacked 03 Jan '13

03 Jan '13

Hi, I entered the command "kamailio -v" instead of "kamailio -V". It looks like it starts kamailio again even that it was running.... the problem is that the kamctl_fifo and kamctl_ctl file are gone now. how do i create the files again without restarting kamailio? Thanks, Uri

All The Best And A Happy 2013!
by Daniel-Constantin Mierla 31 Dec '12

31 Dec '12

This was it for 2012, one of the greatest years in the history of the project! One major release was done in the summer (version 3.3.x), another one is few days before testing phase, most probably to be out by mid of February. The next major release includes several great features and edevelopments: - support for websockets - IMS extensions in the main GIT branch - no more duplicated modules, integration of Kamailio and SER ended There are big plans for 2013. First is the next major release, together with participation at FOSDEM conference in Berlin. A bunch of other events will open the path to our first dedicated conference for Kamailio project - Kamailio World. We hope to meet many of you at Kamailio World conference, in Berlin, Germany, during April 16-17. Last organizing bits were sorted out and registration will open in the first days of 2013 -- you can see more details at: - http://conference.kamailio.com Looking forward to a great 2013 for Kamailio and everyone involved in the project, from developers to community members! All the best! Happy New Year! Daniel -- Daniel-Constantin Mierla - http://www.asipto.com http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

Kamailio TLS setup and certificate
by Burak ÖZTÜRK 31 Dec '12

31 Dec '12

Hi, I m a new kamailio user. Kamailio version is 3.3. I want to enable kamailio's tls support. I fallowed instructions from this link : http://www.kamailio.org/dokuwiki/doku.php/tls:create-certificates And I also enabled tls module in the kamailio.cfg file. (definig WITH_TLS and adding listen=tls:myIP:5061 command) But after trying to start kamailio i got "failed to start" error. When I checked the logs there is nothing about tls or ssl. Actually I got an error while fallowing the link above. "openssl s_client -connect localhost:5061 -tls1" command returns connection failed 111 error. I thought that this is the reason failed to start. But where or what am I doing wrong? I searched the web and hear about SRV records. But there is no explanations about this, on your guide/wiki. I also read this link too but cant get my answer : http://sip-router.org/docbook/sip-router/branch/master/modules/tls/tls.html Is there any idea or a better well-explained user guide about tls support? Regards, Burak

Zero left padding IP in Kamailio
by Techie Sup 30 Dec '12

30 Dec '12

Hello, My IP is 192.168.1.25 and I have added left zero padding i,e: 192.168.001.025 in the configuration file and try to start kamailio, it works.. but along with that rtpproxy does not start. Once I revert back it works. My script requires to add zero left padding for a specific purpose and for that I cannot remove the left zero padding. Any solution to get this work? Regards Selvam

kamailio-ser merging finished
by Daniel-Constantin Mierla 29 Dec '12

29 Dec '12

Hello, in November 2008 was decided to start integration of kamailio and ser project, to get to same source code. About one year later, there was a single source code tree, but there were several duplicated modules that kept some confusion around the two projects. As the time passed, it was shown better what modules are in the focus, making the decisions to sort them out easier. The past weeks were dedicated to removing duplicated, process that just ended -- at this moment there is no duplicated module, all of them being integrated. In summary, the modules from ser that had no conflict were moved as is to modules folder, eventually after rename. The modules with conflicts were merged, adding missing features to the most developed ones, moving the others to obsolete folder. It happened that kamailio version of the modules stayed in the majority of the cases, because they had larger set of features (the core in v3.0.0 was kept from ser). Please note that the extra features from ser modules might not be in the same form, but alternatives that should offer same functionality at the end. People using ser flavour so far should start testing the master branch. Do ask questions on the mailing lists if something that you used to have in config is not longer available, so we can assist in migration and, hopefully, create a migration guide on wiki. There might few bits and pieces to tune here and there, soon we will get into code freezing period for testing the next major release, a good time for such adjustments. It is important that everyone using former ser modules to report the issues that are found. Many thanks to all those involved in integration efforts as well as in new developments that kept the project flying!
