Priority Level timeout:
The maximum time the queue will try to connect a single caller to the agents once in the current level. After the timeout or if no agents are available, the caller will move to the next level. "Off" means the caller will only move to the next level after all agents in the current level have been tried.
The options are to turn this off or to enable and set the priority level timeout between 30 and 240 seconds.

Priority Level mode*:

Option 1. Cascade - 1, 2, 3 - Cascade mode means that the queue will try to deliver the calls to users based on their priority. First to priority 1, then to priority 2, and finally to priority 3.
Option 2. Memory - 1, 1+2, 1+2+3 - Memory mode means that the queue will try to deliver the calls to users based on their priority but everytime it goes to the next level it will add a priority.

Agents in the Queue:
In this part of the page you can configure some settings to users that were added as agents to the queue. You can configure the following settings per user:
Statuses: Logged in, Logged out and paused.
Logged in: Users will be considered by the queue when it distributes the calls.
Logged out: Users will not be considered by the queue when it distributes the calls.
Paused: The paused option gives the same effect as the logged out button but can be used as a clearer visual indicator that the user is temporarily not available.

When a User is added it will give you the option to enable supervisor permissions. Queue supervisor logged in the Operator Consoles can perform Supervisor actions via the Call List widget (accessed from the Queue consoles): listen, whisper, barge in.

Listen : click and listen in without the agent and caller hearing you
Whisper : click and listen in; the agent can hear you, the caller cannot
Barge in : click (sound signal) and listen in; the agent and the caller will hear you
