security purpose.

If set to "Yes", users could disable the extension range pre-
configured/configured on the UCM6510. The default setting is "No".
The default extension range assignment is shown in "Extension Ranges"
below.
Note:
It is recommended to keep the system assignment to avoid inappropriate
usage and unnecessary issues.
The default extension range assignment is:

User Extensions: 1000-6299
User Extensions is referring to the extensions created under web UI-
>PBX->Basic/Call Routes->Extensions page.

Pick Extensions: 4000-4999
This refers to the extensions that can be manually picked from end
device when being provisioned by the UCM6510. There are two related
options in zero config page->Auto Provision Settings, "Pick Extension
Segment" and "Enable Pick Extension". If "Enable Pick Extension"
under zero config settings is selected, the extension list defined in "Pick
Extension Segment" will be sent out to the device after receiving the
device's request. This "Pick Extension Segment" should be a subset of
the "Pick Extensions" range here. This feature is for the GXP series
phones that support selecting extension to be provisioned via phone's
LCD.
