[SR-Users] How to log expiring dialogue?

Hi alle

I think I have an issue with the dialogue and session timer module with Kamailio 5.4

I sync the Session Expire Timer with the dialogue timeout via a common AVP.

When I check a dialogue via kamcmd dlg.list

start_ts: 1682066352 init_ts: 1682066346 end_ts: 0 timeout: 1682066952 lifetime: 600

Timeout is increased on the first session refreshing re-invite, as expected (in this case after 300 seconds). But it looks like the dialogue just disappears (from kamcmd dlg.list, not from the backing database) when the lifetime ist reached, leaving an orphan database entry.

I would like to digg deeper into this. Is there a way to log more details from the dialogue module like when it triggers dialogue expiry?
