3.27 Toll Restriction

Toll Restriction
Toll Restriction limits the numbers an extension user may dial. When accessing a trunk at a remote system
the Toll Restriction Class of Service is defined by the calling extension's system, but the Toll Restriction
tables will be used from the system which has the outgoing trunk. The Toll restriction class number is sent
to the remote system, the remote system will use the class number to define the Toll Restriction tables to
use.
Since the restriction table is used for the system which has the outgoing trunk, the definition of the Class of
Service may be different, unless all Toll Restriction Classes of Service and Toll Restriction Tables are
defined the same between systems.
Operation
Example:
The extension user in System A, which has a Toll Restriction Class 2, dials an outside party after seizing a
trunk from a networked system (System B). The received digits are compared to the Class 2 Restriction
Table in System B. The call is then either allowed or rejected based on this table.
