I have done some more testing and found that this only happens when making using of Local channels. When using the devices like SIP it works as expected:
I have confirmed that my hints are active:
2001@ext-local : SIP/2001&Custom:DND2 State:Unavailable Presence:not_set Watchers 0
2000@ext-local : SIP/2000&Custom:DND2 State:Idle Presence:not_set Watchers 0
Can this be confirmed as a Bug with the queue application?
Using Asterisk 13.
