You can also use the Attendant feature to field incoming calls. Also called the zero out option, the Messaging system forwards a caller to a live operator if the caller presses zero while your greeting is playing. Or you can configure a Personal Attendant to forward your calls to another extension or phone number. If no one answers these numbers, the call is forwarded to a live operator at the main extension or the caller is given the option to leave a message in the original called party's mailbox, based on the system configuration.
