Yes
Dispatch and maybe broadcast cannot be deleted from Jabber. We also ran into a bug with Unity Connection where a job deleted the recordings from one of the two servers in the cluster , so you’d see it and heard it (TUI dials into the secondary, Jabber went to the primary) but you couldn’t delete it. That required TAC to repair.
It uses the REST interface so you could mock up using CUMI as to what is going on.
