I know this system does outcalling from inside the mail box, and I know it can transfer and connect a caller from the auto attendant to an outside line (such as a cell phone or answering service);does anyone know if it can transfer a caller from within a mailbox to an outside line? In the documentation I can only find outcalling info for the mailbox, but nothing about call transfer from the mailbox. If it can be done, does anyone know specifically how?
