In your PBX, make sure you have package 155. You'll need to configure the ACD queues, of course, and ensure you have an Activity Code (ACNT) key on the phones. When you develop your list of codes, think about what you will use for default codes. Do not use 000 as a code -- this is the default value that the "Not_Ready_Default_Reason_Code" takes, and if it is in use elsewhere, statistical calculations (pegging) of the "Not_Ready_Default_Reason_Code" will fail.
