System Programming Options
IMPORTANT:
While procedures that restrict dialing are very effective, absolute protection
against misuse cannot be guaranteed. System phones provide more protection
than standard phones. Therefore, it is strongly recommended that you install
system phones where restricting phone use is important.
Locking an Extension
The system offers a Station Lock feature that lets users enter a four-digit code on
their telephone dialpad to lock their extensions. This helps prevent other users
from making outside calls at those extensions, or from screening calls.
Restricting Access to Outside Lines or Pools
A user can access a line or pool either by lifting the handset, pressing the line or
pool button on the phone, or dialing the Direct Line Pickup feature code or a pool
access code. If you do not want a user to access a specific outside line or pool,
you can use Line Access Restriction (#302) or Pool Access Restriction (#315)
to control an extension's access to a certain line or pool (whether the line or pool
is assigned to the extension or not). Table 2-1 provides examples of settings that
can be used to restrict an extension's access to specific outside lines or pools.
NOTE:
If Forced Account Code Entry (#307) is programmed for an extension, that
extension is required to enter an account code before dialing an outside
number—even those on the Emergency Phone Number List (#406)—on
all of the lines or pools assigned to that extension. If the Forced Account
Code List (#409) contains entries, the system checks the account code
against the list. If the account code is on the list, line or pool access is
allowed; if not, line or pool access is denied.
With Release 3.0 or later, Forced Account Code extensions can dial
numbers on the Emergency Phone Number List (#406) without entering
an account code. Users can make 911 calls from the Forced Account Code
extensions without entering the account code as long as 911 has been
entered into the Emergency Phone Number List (#406).
