Hello, this might be a regression in the acc or dialog module. You could create an issue on our tracker about it with more details, if you like.

This works great so far. When I did my first experiments I even could create a CDR when there was a failover. Since some Versions (we are now on Version 5.6.1) I just get a acc-request in log but no acc-cdr. In former versions this worked. Both server have the same configuration and both server writes cdrs when theres no failover. In case of a failover everything is fine, the dialogs are clean and thanks to dmq all needed variables are replicated between the server. There's just no cdr. I found nothing on the issue-page on github but maybe somebody knows something about it.
