There is also one other cheat using the Transfer Return setting, as long as you want the unanswered call to ring at Ext. 10 and cover to Ext. 10's mailbox - You would set the Transfer Return Setting for EACH voice mail port to itself, NOT Ext. 10. This will cause a transfer from the Auto Attendant to a calling group to return to the voice mail port that sent it there. But it comes back without mode codes, so the next default action is to transfer to Ext. 10, which then rings and covers to Ext. 10's mailbox.
