Modifying An Extension List - 3Com 3C10402B Administrator's Manual

settings back to their original status or click Cancel to return to the
previous window without putting the changes into effect.
Example: If the extension list contains extensions that you assigned to T1
channels, you can assign unique priorities to each extension. If you
instruct the system to place an outgoing call using the T1 line, it attempts
to use the highest priority extension/channel first, and, if the first is
unavailable, tries the next highest priority extension/channel, and so on.
Priorities range from 1 (highest) through 99 (lowest).
CAUTION: If you add an extension list, change the dial plan
configuration file to create a destination route to the new list. This
enables the system to route calls to the new list.
Modifying an To modify an extension list:
Extension List
1 Click Dial Plan > Extension Lists.
2 Click an extension list.
3 In the List Extension field, type an extension number for the extension list.
4 In the Name field, type a name for the extension list.
If you change the name of an extension list, you invalidate any aspect
of the dial plan that refers to the name. You must change all references
to the extension list name in the dial plan configuration file. If you use an
editor to make changes (rather than modifying the dial plan from within
the NBX NetSet utility), reimport the dial plan.
5 If you want calls to cycle through the extensions in the list, enable the
Cycle Extensions check box. Each time the system accesses the extension
list, it uses the next extension in the list. Calls effectively progress through
the list to balance the load of calls. If you disable the Cycle Extensions
check box, the extension selection always starts from the top of the list.
If an extension in the list has a higher priority, the system uses the highest
priority extension regardless of the Cycle Extension setting.
6 To add an extension to the list:
a If the list does not include any members, click the check boxes next
b If the list already has members, click Show all to display a list of
the extension that you want to add to the list.
extensions that you can add to the list's membership.
