Dialing Restrictions:

An Example

■#401—Outgoing Call Restrictions. Using this procedure, you set one of three dialing restrictions for each extension:

■“No restriction” allows long distance, local, and inside calling.

■“Local only” allows local and inside calling only (make sure the Toll Call Prefix is set properly, #402).

■“Inside only” allows inside calls only.

The Outgoing Call Restrictions apply to all lines assigned to that extension. If the call has not been allowed or stopped by any of the preceding pro- cedures, the system looks at the Outgoing Call Restrictions for that extension and determines whether or not the call is allowed.

The following diagram shows what happens when a user makes a call. The sys- tem checks the number against all the dialing restrictions set on the system and the extension. When the number passes a restriction, it goes to the next one, if necessary. When the number violates a restriction, the call is stopped and the user hears a reorder (fast busy signal) tone.

In this example, the user is dialing on a line that has an outgoing Call Restriction set to “local only.” In addition, the extension has an Allowed Phone Number List with a ”1800” entry on it. Notice that the system keeps checking the number until it finds a valid reason to complete it or stop it.
