Featured Presentation

  • None scheduled, but I thought we could maybe talk about gathering information for reporting Jiras and troubleshooting. I've noticed that a lot of people, even those who've been around for a while, are not familiar with all the tools we have for gathering information. (Example: fscore_pb shell script in support-d/ directory)
    • To let sofia debug go to the log file:

In logfile.conf.xml change this: <map name="all" value="debug,info,notice,warning,err,crit,alert"/>

To this: <map name="all" value="debug,info,notice,warning,err,crit,alert,console"/>

FreeSWITCH High Availability Testing

Weekly FreeSWITCH High Availability testing during the conference call. At the end of the weekly conference call the lead developer of FreeSWITCH (anthm) will intentionally crash and restart the conference server. This tests the high Availability that is built into FreeSWITCH. Your call should continue once the server is restarted.

Depending on what type of NAT device will determine if your call is "Re-Invited" back to the conference.
