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

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

OT: results investigating why kamailio.org was not responding recently
by Daniel-Constantin Mierla 11 Mar '15

11 Mar '15

Hello, as some noticed and informed privately or on mailing list, several days ago kamailio.org was not accessible. It was caused by apache getting stuck on connecting to a remote host due to the pingback feature of wordpress. All the other services were fine. Listing running processes showed a large number of apache instances connecting to an address like 23.x.y.204 and being stuck in that state. Fetching the page from that address with wget resulted in some html with embedded obfuscated javascript. I couldn't find a reason why apache was not closing the connection, although there are some timeouts in configs. Also, as I expect apache/php/wordpress don't run javascript, the issue should be somewhere at the http layer. At some point apache reached the max number of threads and didn't serve other requests. The solution was to disable the pingbacks using a plugin for wordpress named: Disable XML-RPC Pingback . All seems ok for the last days. I posted here just in case it will be useful for someone else, but also to get hints on other tweaks that we should to do wordpress to prevent similar situation, if anyone can share from his/her experience.

Calling ims charging function in route_failure
by Shane Harrison 11 Mar '15

11 Mar '15

Hi all, What I want to do ~~~~~~~~~~~~~~ If a call to a SIP AoR fails then try the PSTN number associated with the AoR by routing the request to a PSTN gateway. Calls to a PSTN gateway need to be charged so need to call the Ro_CCR function in ims_charging module. How I tried to do it ~~~~~~~~~~~~~~ In the failure_route[MANAGE_FAILURE] block I call the Ro_CCR() Result was ~~~~~~~~ Kamailio fails to parse config file. yyparse(): misused command Ro_CCR yyerror_at(): parse error in config file //etc/kamailio/kamailio.cfg, line 1162, column 91: Command cannot be used in the block So two questions: 1) What constraints are there for calling functions in the failure_route blocks i.e. how does parser decide what can be called and what can't 2) Any thoughts of how I can do effectively a late charging decision Cheers and thanks in advance Shane Shane Harrison Senior Software Engineer Imagination Technologies NZ Limited Level 2 1 Market Grove Lower Hutt, 5010 New Zealand PO Box 30-449 Lower Hutt, 5040 New Zealand Phone: +64 4 890-3681 ext 3361
