Hi I have the following problem: our FreeSWITCH instance sometimes "forgets" to send a SIP RE-INVITE (we use session timers to periodically send RE-INVITEs on all our SIP channels) which then results in the remote party dropping the SIP channel by sending a SIP BYE to the FreeSWITCH. By sometimes I mean that this happens maybe once for several thousands of RE-INVITEs. I scanned the FreeSWITCH log files but could not find any reason why the FreeSWITCH did not send these RE-INVITEs. But maybe my FreeSWITCH logfile configuration is not "good enough" to show the relevant traces/logs. Does anybody have an idea how to configure the FreeSWITCH logger that would create more helpful logs that would help me find the cause for the missing RE-INVITES? Or any idea why FreeSWITCH forgets the RE-INVITES? We're using FreeSWITCH 1.4.9 on Windows. Our default global loglevel ("loglevel" in switch.conf.xml) is set to "debug". My logfile.conf.xml: <configuration name="logfile.conf" description="File Logging"> <settings> <param name="rotate-on-hup" value="true"/> </settings> <profiles> <profile name="default"> <settings> <param name="logfile" value="C:\Logs\FreeSwitch\freeswitch.log"/> <param name="rollover" value="20971520"/> <param name="maximum-rotate" value="100"/> <param name="uuid" value="false" /> </settings> <mappings> <map name="all" value="all"/> </mappings> </profile> </profiles> </configuration> Thanks, Markus
