Enter all in the From field to deny all transfers. Most administrators choose to deny all transfers, and then allow a few numbers or classes of numbers that do not affect system security.
Enter a starting extension in the From field and an ending extension in the To field to deny a range of numbers.
For example, enter 4000 in the From field and 5999 in the To field to restrict 4-digit transfers to any numbers between 4000 and 5999.
