pretranslators.
An extension list contains extension numbers that you assign and
dedicate to specific dial tone facilities or to specific applications (voice
mail, Auto Attendant, and so on), or both. You can add an extension list
to define a subset of devices, such as fax machines.
The system default extension lists are numbered starting at *0001 in
either a 3-digit or 4-digit plan. By convention, a default extension list
number is preceded by an asterisk. See
standard extension lists.
CAUTION: Extension lists must not overlap.
