Restrictions—Attendant Control of Voice Terminals
You can assign any one of the following six kinds of restrictions to selected extension
numbers or groups of extension numbers:
Outward: Denies direct-dialed calls to the public and private networks. Calls to the
attendant, calls to other telephones/voice terminals, and incoming calls are not affected.
Restricted calls will be routed to intercept tone.
Terminal-to-terminal: Denies incoming calls from other telephones/voice terminals.
Origination of calls is not affected. Restricted calls are routed to intercept tone.
Outward and terminal-to-terminal: Combines both of these restrictions.
Total: Denies all service to an extension number. An attempted call origination or a call from
another telephone/voice terminal will be routed to intercept tone. An incoming direct-dialed
call will be routed to the attendant or to a recorded announcement, depending on your
system.
Termination: Denies all received (incoming) calls to provide a form of “do-not-disturb”
service. Incoming direct-dialed calls will be routed to the attendant or to a recorded
announcement, depending on your system. Other restricted calls will be routed to intercept
tone.
Outward and termination: Combines both of these restrictions.
You can restrict an extension number by dialing the Controlled Restriction access code for
one extension number and by dialing a code number for the specific restriction to be
assigned.
