Managing Extensions 285
Default Auto
Attendant
Extensions Default extension that the system assigns to the default Auto
Attendant. The Auto Discovery process assigns this extension.
The system must direct each call coming in on an external line to
an extension. During the Auto Discovery of external lines
(analog lines and Digital Line Card channels), the system assigns
the default extension (500) as the Auto Attendant extension.
After you import the dial plan configuration file and complete
the Auto Discovery process, you can manually configure the
extension for each analog line and each Digital Line Card
channel.
For both 3-digit and 4-digit dial plans:
■
Extension 500 is reserved as the default Auto Attendant.
■
Extension 501 is reserved as the voice mail Auto Attendant.
Hunt Group
Extensions The range of extensions for hunt groups.
■
4-digit dial plan: 4000–4099
■
3-digit dial plan: 450–499
External
Extensions The range of extensions that are connected to external devices,
such as Analog Line Card ports, Digital Line Card ports (BRI-S/T,
T1, E1, ISDN PRI), Call Park, and Paging extensions.
Default:
■
4-digit dial plan: 6000–7999
■
3-digit dial plan: 600–799
Call Park
Extensions Range The range of extensions for Call Park. This feature allows the
telephone user to park a telephone call temporarily and then
pick it up at a different telephone. Call Park extensions must be
a subset of
external extensions.
■
4-digit dial plan: 6000–7999
■
3-digit dial plan: 600–799
Start External
Discovery At The system assigns extensions to external devices it
autodiscovers, starting with this number and incrementing
upward. If the system reaches the highest extension, it starts
searching from the beginning of the external range and selects
the first unused one.
Typically, systems do not use all of the available external
extensions from 600–799 in a 3-digit dial plan or from
6000–7999 in a 4-digit dial plan.
Default:
■
4-digit dial plan: 7250
■
3-digit dial plan: 750
