A Word about Extension Numbers

Extension numbers are assigned to one-X Quick Edition devices automatically when they are
connected to the Ethernet LAN and powered on for the first time. Extension numbers are
assigned (in the 200-to-299 range by default) in the order that one-X Quick Edition devices
register themselves on the network. These automatically assigned extension numbers are
retained by the devices afterward, even through subsequent power cycles.
It is not usually necessary to change the extension number of a one-X Quick Edition device, but
if you know the password needed to change system-wide settings, you can change any
extension number to a different (unused) extension number manually at any time.
The extension number of a one-X Quick Edition device is stored on the device, which
communicates any changes to its extension number to all other one-X Quick Edition devices
making up the network. Any changes are also communicated to the system-wide Auto
Attendant, and to 4610SW/4621SW IP telephone users through the Corporate directory.
For information about how to change an extension number, see "Managing Extension
Numbers" in the "System Options" chapter of the Avaya one-X Quick Edition System
Administrator Guide.
