If I remember correctly, you may be able to do this. Under system programming in the phone system you will have to activate DCD Ring All on Transfered Call. Set up your Department and add your stations. Know in the Debut, I believe you will have to make a mailbox were the zero out option will go. Then in the Transfer to field, put the Pilot code assigned to the Department. And if I remember correctly, all the phones should ring. Good Luck.
