Overview
A telephone user can look up a call in the call logs (Missed Calls,
Answered Calls, and Dialed Calls) using the telephone display panel,
select a telephone number from any of the logs, and redial it.
To redial a number from the Missed Calls or Answered Calls list, the NBX
system needs to know the appropriate dial prefix to prepend to the digits
in the telephone number.
For information and examples about how to configure outdialing
prefixes, see the Help at NBX NetSet > Dial Plans > Operations >
Outdialing Prefixes.
This section describes how to add, change, and manage extensions:

The NBX system establishes connections between extension numbers.
The concept of an extension applies to more than just telephones.
Extensions are also assigned to NBX applications such as Call Park zones,
Auto Attendants, hunt groups, Line Card ports, voice mail ports, and
virtual devices such as the pcXset™ PC soft telephone Client and the
ConneXtions H.323 Gateway.
The extension length (either 3 or 4), which applies to all extensions on a
system, indicates that all extensions contain that number of digits. You
cannot mix 3-digit and 4-digit extensions within the same NBX system.
The NBX 100 and the SuperStack 3 NBX systems both support 3-digit and
4-digit dial plans, although there are some differences in the extension
ranges as noted in these tables. By default, the NBX 100 uses a 3-digit
dial plan, and the SuperStack 3 NBX uses a 4-digit dial plan.
