Kamailio KEMI Framework Tutorial
by Daniel-Constantin Mierla 24 Nov '17

24 Nov '17

Hello, I started a tutorial for Kamailio KEMI Framework written in markdown format targeting use of mkdocs. It is published on github as part of kamailio-docs repository: * https://github.com/kamailio/kamailio-docs/tree/master/kamailio-kemi-framewo… The mkdocs build (to browse and read) is online at: * http://kamailio.org/docs/tutorials/devel/kamailio-kemi-framework/ It is work in progress and contributions from the community are more than welcome -- doing push requests on github project is the recommended way for contributions: * https://github.com/kamailio/kamailio-docs/ The main goal is document the role of KEMI, its benefits and how it can be used. It addition it should cover the list of functions exported to KEMI by core as well as special KEMI functions. Regarding the functions exported by kamailio modules to KEMI I added as an skeleton the ones exported by acc module. However, I am not sure if we should do it there or add them to the existing docs of the modules. Opinions on this?!?

Issue dumping an huge htable through xmlrpc
by Marco Capetta 24 Nov '17

24 Nov '17

Hello everyone, On Kamailio version 4.4.6 I have an issue dumping an huge htable through xmlrpc. We are using htables to store the subscriber registration attempts to prevent bruteforcing password attacks. Usually there aren't any issues to dump information using xmlrpc. On the contrary, if the number of records in the htable become huge (in the order of 10.000), xmlrpc output is truncated, therefore it is not possible to parse it. I have the same results either using a Perl library or the "xmlrpc_test.py" script included in package. I tried to increase the module parameters "binrpc_max_body_size" and "binrpc_struct_max_body_size" without success. Do you have any other suggestion?

Hi, I've a scenario where multiple mediaservers will be registered to Kamailio and for any incoming call from Upstream provider I've to perform load-balancing to the actively registered media-servers. dispatcher module does load-balancing for IP endpoints, is there any other module where I can perform load-balancing on registered clients(media-servers)? Thanks, Sammy

why do I need rtpproxy
by Wilkins, Steve 23 Nov '17

23 Nov '17

The way I understand it, rtpproxy is needed to pass video/audio through Kamailio to Asterisk. However, even without rtpproxy running, I get video through to Asterisk via Kamailio, and the video plays with no issues on a sip device (e.g. MicroSIP). I am confused what I need rtpproxy for. Thank you

rfc: clang format the code
by Daniel-Constantin Mierla 23 Nov '17

23 Nov '17

Hello, it was discussed during the last irc devel meeting and everyone there agreed to use clang-format to format the source code: - https://clang.llvm.org/docs/ClangFormat.html Is any developer (maybe not present during the irc devel meeting) opposing this? It is not going to be all at once, because some of the structures and initialization of them may be preferred to be kept with a custom format for being easier to read -- to have a section in the file not formatted, it has to be enclosed in between comments: /* clang-format off */ ... /* clang-format o. */ But for the rest of the code (i.e., functions) I think it will be better to agree on a format and try to use it. The clang-formatting should be done when one needs to update code in some files. Over the years, developers come and go, having each one with a custom formatting style is hard to maintain properly in long term. There are modules that do not indent coherently code inside blocks, using a mixture, more or less no style. This makes it hard for other developers to review in case of reported issues, but also for new comers to get familiar with the code. In the source tree there is already a .clang-format file which defines the options for formatting. It was used by me and other developers already -- I did it mainly in my modules or those components that do not have an active maintainer. But I plan to do it also on the components that have currently a maintainer at the moment I need to work on that code (e.g., fix some issue or export functions to kemi framework). My process of clang-formatting a module is like: - edit the files to add clang-format off/on comments around the parts I want to preserve as they are (typically mod exports -- params, functions, kemi -- and intialization of structures that are aligned to a specific indentation that makes it easier to read). - run: clang-format -i src/modules/modname/*.{c,h} - commit with these changes, no new feature or bug fix must be done in the same commit (can be combined with removing the history comments) If one wants different options inside .clang-format, please propose and let's discuss which one is preferred by the majority of the current developers. If no one shows anything against in a matter of few days, it will be considered accepted (after all, one can re-indent on own style if the rule is not accepted or overturned).

Error when attempting to use rtpproxy
by Wilkins, Steve 23 Nov '17

23 Nov '17

Hello, I entered this question before but did not include the tcpdump file. I am re-posting just in case this message was over looked for lack of information. I am using Kamailio version 5.0.3 (x86_64/linux), and it is installed and working on a Centos 7 Sever. I use Kamailio as a SIP Proxy Server for Asterisk and things seem to work fine, however, I do have an issue and a question for which I am trying to understand and am hoping someone can help me with. My server name is vadev2 (Kamailio run on this server), and it's IP Address and port are 172.21.1.108:5060; Asterisk servers are (172.21.1.97:5060, and 172.21.1.124:5060). The rtpproxy is 172.21.1.108:17722 Issue: Every 10 seconds I get an Error message in the Kamailio log which says => Nov 13 18:10:55 vadev2/usr/local/sbin/kamailio[29188]: ERROR: <core> [core/tcp_main.c:2660]: tcpconn_1st_send(): connect 172.21.1.108:59794<http://172.1.1.13:59794> failed (RST) Connection refused. I do not know what triggers this error, and as mentioned, things do seem to work, other than I do not believe anything is going through rtpproxy; I can make calls and use sip tools which pass requests through Kamailio to Asterisk. Does anyone know what could be causing this Error? I do not understand what is trying to connect to what and why. Should I be using rtpengine instead of rtpproxy? I did attempt rtpengine but it would not compile due to missing json.h files. Thank you for any help -Steve
