Hello,
a new module was committed in trunk, to be released as 1.5.0 - the plan at: http://www.kamailio.org/dokuwiki/doku.php/features:new-in-1.5.x
The rtimer module allows to execute route block on timer. It can create new processes that will do the timer execution of the routes or use existing timer. There can be multiple timers and each timer can execute multiple route blocks.See readme at: http://kamailio.org/docs/modules/devel/rtimer.html
Such features is useful if you want to do periodic jobs in your service
1) clean a database were you store temporary data - e.g., delete entries older than 2 hours
modparam("rtimer", "timer", "name=ta;interval=10;mode=1;") modparam("rtimer", "exec", "timer=ta;route=8")
route[8] { sql_query("ca", "delete from tmp where timeval<$TS-3600","ra"); }
2) save statistics in database so you can build graph, etc... http://www.kamailio.org/dokuwiki/doku.php/pseudovariables:devel#statistics
route[8] { sql_query("ca", "insert into kamailio_stats values ($stat(...), ...)","ra"); }
3) Along with another pretty new feature - sending sip requests from config file: http://lists.kamailio.org/pipermail/users/2009-January/021426.html
you can implement keep-alive/syncronization mechanisms within your farm of sip routers.
Any other ideas? Let's see the best one for using the new stuff from uac and the rtimer module...
Cheers, Daniel
