System Renumbering
NOTE:
In Release 6.0 and later systems (Hybrid/PBX mode only) where local
users will dial extensions on a remote networked system, UDP procedures
are used to number these extensions so that local users can reach these
extensions as though they were on the local system. This section describes
only the numbering for local extension numbers. For detailed information
about numbering non-local dial plan extensions, see

Description
System renumbering is the process of reassigning extension numbers to all types
of extensions, adjuncts, lines/trunks, telephones, ranges of extensions on a DSS,
ARS, calling groups, Idle Line Access, LDN, paging groups, park zones, pools,
and remote access.
When the system is turned on, it identifies the type of module installed in each slot
in the control unit and automatically assigns extension numbers. When assigning
extension numbers, the system begins with the lowest-numbered slot containing
extension jacks and assigns numbers starting with the bottom (lowest) jack and
moving consecutively up to the top jack. The system then moves in ascending
order to the next slot that contains extension jacks and repeats the process.
The factory default assigns 2-digit extension numbers, starting with Extension 10.
Both the number of digits and the extension numbers assigned by the system can
be changed to address a company's needs. For example, extension numbers can
match room numbers.
NOTE:
If a user needs a specific extension number, it is simpler to connect the
user's telephone to the extension jack that is already assigned the
requested extension number than it is to renumber the jack where the
telephone is connected.
Whenever extension numbers are renumbered, the following must be considered:
Extension numbers can contain the digits 0 through 9 in any combination,
except that no extension number can begin with 0. Zero is a fixed
extension number representing the primary system operator. The system
also can be programmed to associate 0 with a QCC operator position.
Extension numbers can contain one to four digits and must be unique. If
you renumber an extension number with one or two digits, you cannot use
those digits as the leading digits for a longer extension number. For
