Re: [SR-Users] Regd. Kamailio GPL
by Alex Balashov 13 Mar '15

13 Mar '15

I am also not at all an expert in GPL licencing or IP, but would like to add that any customisation you make specifically for the purpose of interacting with a billing server or other external application is likely to take the form of a Kamailio module, rather than modifications to the existing Kamailio modules, the Kamailio core, or any other part of the stock code tree. As far as I know, under the GPL--broadly speaking, for I certainly don't know or remember the specifics--modules get different treatment than modifications per se. As far sa I know, if you can stick your code into [a] completely self-contained module(s) (and given what you've said about what specifically you want to accomplish, it seems to me that you absolutely can) that interact(s) with Kamailio using its module APIs and requires no modifications to Kamailio itself, it's not subject to the same licence constraints as modifications per se. Please do not take my advice as stated, and consult a competent software/IP attorney. -- Alex -- Alex Balashov - Principal Evariste Systems LLC 303 Perimeter Center North Suite 300 Atlanta, GA 30346 United States Tel: +1-678-954-0670 Web: http://www.evaristesys.com/

Loadmodule mi_xmlrpc.so gives error
by SamyGo 13 Mar '15

13 Mar '15

Hi All, Im trying to load up module 'mi_xmlrpc.so' into my v4.2.1 Kamailio. It compiles nicely but when I try to load the module in config and restart kamailio it gives following error(s) 0(30917) ERROR: <core> [sr_module.c:597]: load_module(): could not open module </usr/local/lib64/kamailio/modules/mi_xmlrpc.so>: /usr/local/lib64/kamailio/modules/mi_xmlrpc.so: undefined symbol: xmlrpc_strsol 0(30917) : <core> [cfg.y:3436]: yyerror_at(): parse error in config file /usr/local/etc/kamailio/kamailio.cfg, line 329, column 12-25: failed to load module 0(30917) ERROR: <core> [modparam.c:166]: set_mod_param_regex(): No module matching <mi_xmlrpc> found Now, I've done some searching around and it seems like pre-req library version mismatch thing.. Do you guys have any solution to this. My end objective is to be able to send MI commands to my Kamailio server(s) via web-Interface. Any recommendations, examples are welcome. Best Regards, Sammy.

Kamailio and rtpengine Load Testing
by Marc Soda 12 Mar '15

12 Mar '15

I'm wondering if anyone has any experience load testing with Kamailio and rtpengine using WebRTC. I've had success load testing just Kamailio with sipp, but now I'd like to add the media piece and, if possible, do it via WebRTC. Anyone have any thoughts? Thanks, Marc

But gnu.org points out that above assumption isn't always true: http://www.gnu.org/licenses/old-licenses/gpl-2.0-faq.html#GPLRequireSourceP… "The GPL does not require you to release your modified version. You are free to make modifications and use them privately, without ever releasing them. This applies to organizations (including companies), too; an organization can make a modified version and use it internally without ever releasing it outside the organization. But if you release the modified version to the public in some way, the GPL requires you to make the modified source code available to the program's users, under the GPL." So if you don't ship a binary to endusers, you don't have to release source (including modifications). It all depends on what you are supplying to your endusers (a service or a (complete) software product).

Hi, Thank you very much for the clarification. Our intention is to provide VOIP service and hence we need not expose our customized code to end users.

For GPL2, providing services is not seen as distribution of the source, and the commercial code can stay in the company. For GPLv3 it's different as far as I understand. Kamailio is GPLv2 and Siremis - the web interface by Asipto - is GPLv3. /O

Parser error with sql_pvquery?
by Anthony Messina 12 Mar '15

12 Mar '15

I'm trying to do an sql_pvquery() and have PostgreSQL return the default value using COALESCE (if the other parts of the query return NULL) rather than placing the $null check on the return in the Kamailio script. I seem to be coming up on a parser issue, perhaps too many nested parentheses: sql_pvquery("kamailio", "SELECT COALESCE((SELECT value FROM usr_preferences WHERE attribute='callee_rtp_transport' AND (uuid='$sht(rtpengine=>$ci::$T_branch_idx::callee_ip)' OR username='$rU') LIMIT 1), 'RTP/AVP')", "$sht(rtpengine=>$ci::$T_branch_idx::callee_rtp_transport)"); <core> [cfg.y:3428]: yyerror_at(): parse error in config file /etc/kamailio/kamailio.cfg, line 1444, column 14: syntax error Is this query "too complex" for the parser, or is there something I've missed above? Thanks. -A -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery 8F89 5E72 8DF0 BCF0 10BE 9967 92DC 35DC B001 4A4E
