[SR-Users] Parsing Error in Timer Module of kamailio

Hi Team, Greetings! I am trying to use Timer Module of Kamailio to keep calling particular route at particular time interval. Here is the snippet of my config: loadmodule "timer.so" modparam("timer", "declare_timer", "MYTIMER=SHUTDOWN,5000,slow,enable"); route[SHUTDOWN] { xlog("system shutdown: $sht(graceful_shutdown=>shutdown)\n"); } But after restarting the Kamailio, I keep on getting parsing errors in every 5 sec and my route "SHUTDOWN" never get called. Which means timer is getting called in every 5 sec but not able to call the route. Could you please help me with this why these parsing errors coming? am I missing some arguments here? Kamailio Version: 5.5.X.

But Could you please help me with the pros and cons of both the modules timer and rtimer. Any thoughts on this would be appreciated Surabhi Garg Mobile - 91 783 888 7523
