Hi Celine,
Are you setting the priorities before the calls are placed? While changes to the Priority setting take effect immediately in a running campaign, calls in the queue are not affected by changes in campaign priority, as campaign priority is only considered when placing calls.
You can find more info about call priority using the following Resource Center articles:
