Managing Extension Lists
65
Within an extension list, you can assign a priority to each extension.
When the system accesses an extension list, it tries to use the highest
priority extension first. The highest priority is 1 and the lowest is 99.
For example, If the extension list contains extensions that are assigned to
T1 channels, you can assign unique priorities to each of the extensions.
If you instruct the system to place an outgoing call using the T1 line,
it attempts to use the highest priority extension/channel first. If the first is
unavailable, it tries the next highest priority extension/channel, and so on.
From the Extensions List tab of the Dial Plan window, you can perform
these tasks:
■
Adding an Extension List
■
Modifying an Extension List
■
Removing an Extension List
The system restricts access to any specific Analog Line Card port or Digital
Line Card port. To directly dial the extension number that is associated
with one of these devices, you must have diagnostic privileges. In
addition, you cannot dial a prefix to obtain a Digital Line Card port.
