DnD

Do not disturb mode is when only calls from the Queue(s) come to the Agent.

When an Agent turns Do Not Disturb mode on, he cannot accept internal calls from other system Users. Only calls from Queues will be routed to him.

 - the switch is in the on position, the Agent receives calls only from the Queue(s);

 - the switch is in the off position, and the Agent receives all calls from Queues and other Users.

If an Agent or system User has the Do Not Disturb mode enabled, such an Agent will be displayed with an  indicator in the list of Users.
