VP: Restricted Numbers
NTVP: Restricted Numbers (Call Restrictions tab)
When a mailbox owner calls in to change his/her call-transfer number, pager number, or
message notification number, you may want to prevent him/her from changing it to certain
numbers, such as long-distance numbers.
These fields allow you to define digit sequences that are to be blocked. The VP system looks
at each of these Digits fields to determine if any of them match the number entered by the
mailbox owner. If the number entered by the caller begins with the digits specified in the
Digits field, the VP system defines the number entered as a match.
For example, if you enter the digits 1900 in one of the Digits fields, the VP system considers
the telephone numbers 1-900-555-1212, 1-900-123-4567, 1-900-111-2222 to be matches.
Telephone number 1-901-555-1212 would not be considered a match.
If you enter the digit 0 in one of the Digits fields, the VP system considers all numbers
beginning with 0 to be matches. This would include calls to the operator (0), calls to the long-
distance operator (00), international calls (011), and any operator-assisted call (0 followed by
telephone number).
If the caller enters a number that matches one of the digit strings you enter here, the VP
system informs the mailbox owner that the number is not acceptable and retains the current
set up.
