Hello FreeSWITCHers! I've found that in a conference (mod_conference) a re-invite is sent by FS at around 900 sec after call confirmed (ACK). This has nothing to do with session-timeout (eg, session-expires) that are both set to 1800, and sent by FS and clients accordingly. I can see this behavior only in conference (but maybe is elsewhere?). I've looked into both mod_sofia and mod_conference sources, but I've not found anything related. I've tried to debug the call with all kind of debugging/tracing (sofia lib, mod sofia, internals, etc etc) but I've not found any hint of what can trigger that reinvite. Is it configurable? Have a nice continuation, keep on with the superb work, -giovanni -- Sincerely, Giovanni Maruzzelli OpenTelecom.IT cell: +39 347 266 56 18
