2-62 Calling Restrictions
A user with an outward-restricted or toll-restricted telephone cannot add an
outside participant to a conference unless the participant's number is on an
Allowed List assigned to the telephone.
However, if a conference originator with an outside caller presses the
Conference button, selects an outside line, and presses the Conference button
again before dialing a number, the outside caller can dial a toll call, thereby
overriding calling restrictions assigned to the conference originator's telephone.
The toll call is billed to the conference originator's company.
Calling restrictions can be assigned to DLCs. Since restrictions apply to the
telephone used to initiate a call transfer to an outside number, a user with a
restricted telephone can circumvent restrictions by asking a system operator
with an unrestricted console to connect an outside call.
Disallowed Lists can be assigned to restricted telephones. Disallowed Lists take
precedence over Allowed Lists. If a telephone number is on both an Allowed List
and a Disallowed List and both are assigned to an individual telephone, the user
cannot dial the number.
The "Call Denied" message is shown on an MLX display telephone when a call is
denied because of calling restrictions. The message is not shown on an analog
multiline display telephone.
To allow users in the hotel/motel configuration of Extension Status to dial
emergency or other selected numbers when the telephone is in status 1 or 2,
access must be assigned to an Allowed List.
A user with an outward-restricted telephone cannot forward calls to an outside
number unless the number is on an Allowed List assigned to the telephone. A
user with a toll-restricted telephone cannot forward calls to a toll number unless
the number is on an Allowed List assigned to the telephone. No error tone
sounds when the user with a restricted telephone activates the Forward feature;
however, when a call is received at the station, 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 consisting of emergency numbers that can be dialed from
any telephone without dialing the password. Any restrictions assigned to a
telephone on the exclusion list are in effect when Night Service is activated.
A user with an outward-restricted telephone cannot dial an outside number on a
Personal Line button unless the number is on an Allowed List assigned to the
telephone. A user with a toll-restricted telephone cannot dial a toll number on a
Personal Line button unless the number is on an Allowed List assigned to the
telephone.
