Selectable numbering plan
The selectable numbering plan offers up to three pre-configured numbering plan ranges that begin with
100, 200, and 300. When an extension numbering range is selected, department numbers and guest
mailbox numbers are also changed. However, regardless of which extension numbering range is se-
lected, feature codes, CO line groups, cascade mailboxes, group mailboxes, and Q & A mailboxes will
stay the same. The numbering plan range is selected in Installer programming.

Notes: For each table, ranges different from the default dialing plan appear in bold.
The ESI Presence Management RFID Reader

uses one digital extension, regardless of the numbering
plan chosen.
