When a caller presses 0 to reach an attendant, the system transfers the call to the to the assigned extension.
If the attendant does not answer, then the system transfers the caller to a general-delivery mailbox so that the caller can leave a message.
Never (the default)
Always
If you do not enter an extension number, when the caller presses 0, the Messaging system updates the caller that no operator is available and disconnects the call.
If you entered an extension number in the Operator (live attendant) extension field and if the attendant does not answer, then the system transfers the caller to this mailbox.
