With the active voice I used to do this kind of thing with Transaction boxes, but it seems to me that you should be able to route Attendant automatic call forward no answer to a box with a message that the attendant is busy and to continue to wait for the attendant dial O again. Might be able to give another option for leaving a message. If not just get a viking aca-1a (or something similar) as the automatic no answer point and tell them to continue to hold for the operator dial O or dial xyz to leave a message. That would allow you to utilize the embedded AA. Or you can put the stand alone AA in front of the system and set up supervised transfer, but you could run into other problems. Better to set up the AA as the console no answer forward point. Just make sure that you have camp on enabled on the trunks to allow them to camp on to the hunt group with the AA in it so the calls will queue if the AA is busy. Best I can do.
