In Hybrid/PBX mode, a user with a restricted extension can use
Callback for a busy pool because restrictions are based on the specific
trunk being used to make the call. When a trunk in the busy pool is
available, the system checks for restrictions assigned to the extension.
If the extension is restricted, the user hears a fast busy signal to
indicate that the call is not allowed.
A user with an outward/toll-restricted extension cannot add an
outside/toll participant to a conference unless the participant's number
is on an Allowed List for that extension.
In Release 2.1 and later, users answering calls on Cover buttons can

denied because of calling restrictions. The message is not shown on an
analog multiline display telephone.
To allow users in the Hotel configuration of Extension Status to dial
emergency or other selected numbers when the extension is in Status 1
or 2, the extension must be assigned to an Allowed List.
A user with an outward- or toll-restricted extension cannot forward calls
to a number (outward or toll) unless the number is on an Allowed List for
that extension. No error tone sounds when the user with a restricted
extension activates the Forward feature; however, when a call is
received at the extension, the system checks restrictions and denies the
forward if the number is not on the Allowed List.
For Night Service with outward restriction, a Night Service Emergency
Allowed List must be created; it consists of emergency numbers that
can be dialed from any extension without dialing the password (10
emergency numbers, 9 digits each). Any restrictions assigned to an
extension on the Night Service Exclusion List are in effect when Night
Service is activated.
A user at an outward-restricted extension cannot dial a restricted
number (outward or toll) on a personal line unless the number is on an
Allowed List for that extension.
Specific pools can be restricted from being used for outgoing calls by
assigning a pool dial-out code restriction to extensions.
