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,
