Hi Calvin,
Iam not using dmq but there are different aspects.
First what you assume it should do.
Second what the module documentation described and last what in reality
happens.
Did you try it in a test setup with your config and if it is "broken" in
your opinion, you can then fill an issue for the devs with an minimal setup
description and how to recreate the issue.
That would I do.
Kind regards
Karsten Horsmann

The question is whether that DMQ synchronization for
dialog data is
sending all dialogs or only delta/incremental data. Some SBCs I've worked
with only synchronize new dialog data, leaving standby nodes only aware of
dialogs established since restarting or joining the cluster, not existing
dialogs. In that circumstance, a failover to the restarted or new standby
would break any dialogs created prior to the restart.
If Kamailio dialog DMQ synchronization is "complete" then we just need to
know how to confirm the new standby is synchronized before performing a
failover.

Hello,
are you aware of the DMQ synchronisation for dialog data? It’s not
replicated everything, but certainly a way to seed the dialog information
after a restart.
Another way is of course the usual shared database, just keep in mind
that you need to configure the dialog module (hash table “step” variables”)
to properly work.
Cheers,
Henning

*Subject:* [SR-Users] Dialog DMQ state after restart
Does the dialog module do anything similar to the htable dmq_init_sync
behavior?
The scenario is restarting the offline member of an HA pair after
modifying the script. We're unsure of the state of the replicated dialogs
post-restart. Will the standby become aware of the dialogs prior to the
restart? In other words, do we need to wait until the pre-restart calls end
before we can safely failover?
