My account has a work around method that takes a Call Queue that I am included in and it forwards to a Queue that I am not included in but behaves identical to the first one. When the custom rule is turned on within the first Queue it allows me to NOT be a part of those incoming Call Queue Calls. If I turn it off, then I can receive and answer Call Queue Calls for that specific Queue. If a user is a part of more then one Queue, he/she might wish to accept or not accept calls from specific Queues. I amanage more then 1 Queue and I need one turned on while the other is turned off.
