Changing Extensions
You can perform several operations through the Modify Extensions dialog
box (Table 10). This section describes several examples.
Example:
If you select
Change Extension
from the
Operation
list, the
system replaces the selected extension with the number you type in the
text box.
Example:
If you select
Strip Leading Digits
from the
Operation
list, and
type the number 2 in the text box, the system strips (removes) two digits
from the beginning of the extension.
Example:
If you select extensions 1000 through 1009 and select
Strip
Trailing Digits
from the
Operation
list, the system does not make any
change, because the result is a series of identical numbers (all 100).
Managing
Extension Lists
An extension list contains NBX extension numbers that are assigned and
dedicated to specific dial tone facilities or to specific NBX applications
(such as voice mail, Auto Attendant, and so on), or both. You can add an
extension list to define a subset of devices such as fax machines.
Extension lists are typically numbered upward starting at *0001 in either
a 3-digit or 4-digit plan. By convention, the extension list number is
preceded by an asterisk. See Table 11 for a description of the standard
extension lists.
CAUTION:
Extension lists must not overlap.
Prepend
Prepends the digits in front of all selected extensions.
Append
Appends the digits to the end of all selected extensions.
Strip Leading Digits
Strips (removes) the specified number of digits from the
beginning of all selected extensions.
Strip Trailing Digits
Strips (removes) the specified number of digits from the end
of all selected extensions.
