Instruction manual

Large business communications systems
5-22 Issue 9 May 2003
To activate the desired controlled restriction, the attendant or voice terminal user
with console permission dials the feature access code for either the extension or
the group, followed by either 1 for Outward, 2 for Total, 3 for Termination, or 4 for
Station-to-Station, and then dials the voice terminal extension number (Attendant
Control — Extension) or the COR for a group of voice terminals (Attendant
Control — COR).
This feature is especially helpful in businesses such as hotels, where you might
want to restrict phones in empty conference rooms or in guest rooms after a client
has checked out. You might also want to restrict phones in an entire wing of a
building at times.
Central office restrictions
Some Central Offices offer additional services that screen long distance calls,
such as 0 + calls and 101xxxx+ calls. Contact your local telephone company for
details.
Restricting incoming tie trunks
You can deny access to AAR/ARS/WCR trunks when the caller is on an incoming
tie trunk. For all the switches, you can force the caller to enter an authorization
code when AAR/ARS/WCR is used.
Use the COR of the incoming tie trunk to restrict calls from accessing the network.
Set the calling party restriction to
outward, set the FRL to 0, and specify n for all
other trunk group CORs on the calling permissions screen.
Authorization codes
Authorization codes can be used to protect outgoing trunks if an unauthorized
caller gains entry into the Remote Access feature. Authorization codes are also
used to override originating FRLs to allow access to restricted AAR/ARS/WCR
facilities. They can be recorded on SMDR/CAS to check against abuse. Refer to
the description of authorization codes in ‘‘Authorization codes’’ on page 5-8
.
The list command can be used to display all administered authorization codes.
