OVERVIEW
Toll restrictions allow you to place restrictions on outbound toll calls, per tenant group and account code.
BASIC TOLL RESTRICTION PROGRAMMING TASKS
In order to program the toll restrictions for use, you will need to perform the following basic tasks:
• Set up Class of Service and Digit Interval
• Program the account code length and passwords and passwords
Class of Service and Digit Intervals
• The DX-120 provides sophisticated monitoring of outbound digits dialed by callers on CO lines. You can assign
COSs for a broad range of call control.
For example, if a digit or range of digits dialed on a CO line is inconsistent
with the dialing extension’s or CO line’s class of service, the system denies the call.
You can apply this calling
COS criteria to local calls, long distance calls, and specific numbers that are considered allowed in areas where
other numbers may be restricted.
• The DX-120 provides a toll restriction table of 100 entries. Each entry can contain 10 digits in the "From" column
and 10 digits in the “To” column. These fields allow you to specify a range of digits in a truth-table fashion known
as digit intervals.
• You then set extension COS and CO line COS per table entry as Y/N (e.g., does this table entry apply to this
COS? Yes or No.). You specify two conditions for extension and CO line COS assignments, per table entry: Day
mode and Evening mode. This allows you to assign each table entry to each COS differently for these day or
evening modes.
EXAMPLE:
• An example of a table entry may be as simple as “From 0”, “To 0”. The result of this
truth table is that the system monitors calls associated to this COS for only the first
digit dialed. If that digit is “0”, the system allows the call and no further restriction
monitoring takes place.
• Another example is a table entry of “From 1813412”, “To 1813450”. In this case,
the system monitors calls in this COS sequentially for the first seven digits dialed,
or until the caller enters the first digit inconsistent with this setting. Thus the system
denies a call dialed as 1813410 as soon as the caller enters the digit “0”. The
system allows the caller to dial 1813419 + any digits.
• Conditions for Assigning Class of Service and Digit intervals
- Digit interval 001 is programmed as: From “0”, To “#” (this allows all digits to be dialed).
- You can program up to 100 digit intervals, 10 per tenant group.
• Callers can override an extension’s class of service if you set up an account code password that instructs the
system to use a different class of service for the call.
