I have users who are members of multiple call queues. If they accept a call from one queue, is there a way to prevent other queues from attempting to put calls through to their extension? Can other queues recognize that extension is already on a call? I already have Maximum Concurrent Calls set to 1 for each queue, and “include direct calls” selected, but the system does not seem to be able to recognize when a user is on a call from a different queue.
