[Freeswitch-users] freeswitch continously sending sip update-messages: why?

I'm testing freeswitch as an sbc (version 220.127.116.11). I think I discovered a
bug, but I still have to verify it against git if I can find the time to
compile it. Anyway, it all relates to session-timer according to me, but
even if I disable session-timers, freeswitch still sends
sip-update-messages to the sip-client. Freeswitch is dropping the calls
after 30 seconds because of this. There is no problem with natting,
firewalling, ... as far as I can tell as I'm tracing the packets on all
ends. A packet from freeswitch to the sip-client (phone behind other

The other end of the sbc/client doesn't support session-timers or update
(yate client), and it doesn't have this problem.
So, the main question is:
--> Why is freeswitch sending these update-messages while the codec, ...
remains the same as far as I can tell. It isn't a session-timer, because it
is enabled in the profile and it doesn't appear in the message too (which
means the disable had some influence ...)?
So, is there a way to:
1) fix the above?
2) force session-timers to use reinvite instead of update. As this case
may be a way around the bug (freeswitch doing as it is the refresher while
they agreed that the client is the session-timer-refresher).
3) (asked before, but not answered) Is there a way to disable
sip-"update"-message-support in freeswitch?
Thank you and kind regards,
