ShoreTel 7.5 Administration Guide 2 – 3
Parameters
The parameters on the Edit Dialing Plan page are as follows:
Number of Extension Digits This parameter tells you the current number of
extension digits on the system. The ShoreTel 7.5
system supports extension lengths of 3, 4, or 5
digits. The default is 3 digits.
To increase the extension length, click the Increase
Extension Length link. Due to the scope of the
change, this procedure requires you to stop and
start the ShoreWare voice services as well as the
ShoreGear voice switches. Also see “Increasing
Extension Length” on page 2-5.
Dialing Plan These parameters let you reserve digit ranges for
the configuration of trunk access codes and dialed
numbers.
The Reservation list lets you select one of the
following:
• Extension Prefix (n digits) — For use with the
On Net Dialing feature. Click on the drop-
down menu to the right of the desired digit and
select the number of digits you would like the
extension prefix (i.e. site code) to contain.
Extension prefixes can range from 1 to 7 digits
in length. The leading digit determines the
length of the prefix. Extension prefixes with
different leading digits do not have to contain
the same number of digits.
Note: The Configure Extension Prefix Warning
window appears with a list of each of the sites
in your system. Next to the list of sites you will
find a blank field that requires you to enter the
desired extension prefix. This prefix will be
applied to every dialed number at that
particular site. Make sure to back up the system
before clicking Save.
• Extensions—Reserves this range for use by
extensions, mailboxes, distribution lists, and
menus. Note that the digit “0” cannot be
reserved for extensions.
• Not Used—Does not allow this range to be
used.
• Operator—Defines the digit as a shortcut for
reaching the site operator with the telephone.
By default, the system is programmed with “0”
as the operator digit.
• Trunk Access Codes [1 Digit]—Defines the
range solely for 1-digit trunk access codes.
