[Freeswitch-users] RE-Invite in conference

[kaiduan xie]

 Giovanni,
I think the reINVITE is sent by session timer. 
Per rfc4028 https://datatracker.ietf.org/doc/html/rfc4028#section-10

It is RECOMMENDED that this refresh be sent once half the session interval has elapsed.
900 seconds = 1/2 * 1800

 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
