Features
In conjunction with FRLs assigned to routes, FRLs from 0 to 6 are also assigned
to extensions and are used to determine whether callers have permission to use
the routes. For an extension, 0 is the most restricted and 6 is the least restricted.
To use a route, the extension must have an FRL equal to or greater than the
route's FRL. In other words, an extension with an FRL of 0 has the fewest ARS
privileges (routes with levels 1 through 6 cannot be used), and an extension with
an FRL of 6 has the most privileges (any route may be used).

In Release 3.1 and later systems, default FRLs help system managers guard
against toll fraud. These restrictions are automatically applied to routes, voice
messaging ports, and to the barrier codes of remote access users, as follows:
Routes. The default FRL is 2 for default local routes, so system managers
can easily change an extension default of 3 to 2 or lower in order to restrict
calling. No adjustment to the route FRL is required.
Voice Messaging Ports. The default FRL is 0, restricting all outcalling.
Barrier Codes. The default FRL is 0, restricting all but inside calls.
