Hi Joel,

Thank you, I was reading it yesterday. See this issue 
https://github.com/kamailio/kamailio/issues/2080#issue-499544483 – in my tests 
the proxies will expire the dialogs even after a restart. I just tested it 
again even restarting both proxies a few times.

Cheers,

Henning

Just a note, I would suggest to use htable+dmq to  do such limits, dialog+dmq 
has some issues when handling dialog expiration when a node for whatever reason 
is restarted.. (search GH issues and you will find one with a long thread where 
Charles explains the reasons: TL;DR: You could  end up having inconsistent 
dialog information with dialog+dmq)

Hope it helps!
Joel.

The update_period should have no impact when db_mode=1 -- in this case
the records are written to database immediately. I think update_period
is intended only for db_mode=2.

Cheers,
Daniel
