You can modify the extension number of any device in the system.
Normally, you make changes only after you have changed the extension
ranges for the system, to align the extensions with the new ranges.
CAUTION: Be careful when you change extensions. The system does not
validate changes that you make, and there is no Undo or Cancel function.
A mistake can compromise the operation of the system.
To modify extensions:
1 Click Dial Plan > Configure.
2 Click the Modify Extensions tab.
3 Select the extension, or extensions, that you want to modify. To select all
extensions, enable the Select check box.
4 Select an operation from the drop-down list and make the appropriate
entries in the field, which display after the member list:
Change Extension — Modifies the first selected extension with the
■
number you type in the field next to the drop-down list. Change
Extension applies to only one extension at a time. If you select multiple
extensions, the system changes only the first extension that you
selected.
Prepend — Prepends digits in front of all selected extensions.
■
Append — Appends 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. For example, if
you type the number 2 in the field, the system strips (removes) two
digits from the beginning of the extension.
Strip Trailing Digits — Strips (removes) the specified number of
■
digits from the end of all selected extensions.Click Apply to make the
changes, or click Reset to restore the settings to their original status.
If the requested change creates a duplicate extension or an extension of
zero length, the system discards the change. For example, if you select
extensions 1000 through 1009 and select Strip Trailing Digits, the system
makes no change, because the result is a series of identical numbers (all
100).
The Convert Extensions feature enables you to use the NBX NetSet utility
to change these extension types from 3-digits to 4-digits or from 4-digits
to 3-digits quickly:
