The MERLIN LEGEND Communications System ships with ARS activated and all
extensions set to Facility Restriction Level 3, allowing all international calling. To
prevent toll fraud, ARS Facility Restriction Levels (FRLs) should be established
using:
 FRL 0 for restriction to internal dialing only
 FRL 2 for restriction to local network calling only
 FRL 3 for restriction to domestic long distance (excluding area code 809 for
the Dominican Republic, as this is part of the North American Numbering
Plan, unless 809 is required)
 FRL 4 for international calling
Each extension should be assigned the appropriate FRL to match its calling
requirement. All voice mail port extensions and barrier codes not used for
outcalling should be assigned to FRL 0, which is the default setting for voice mail
ports starting with Release 3.1. Prior to this release, the default setting is FRL 3.
