This is related to my previous posting. I have been having trouble getting calls to be forced to make set busy. If the phones are logged in to the queue and on NRD, call just rings and rings untill the call is picked up at that phone. If the phone is not on NRD and in the queue, the call is forced to msb,is logged out and call goes to voice mail. Will NRD not work if there is no call treatment ex. music on hold, ran routes ?
